LETHAL COMBINATION - PART II


LETHAL COMBINATION - PART II:

DDD’s BUBBLE BUSTED;
PACMAN IN RUNAWAY TRIUMPH

Doods A. Amora, PEE
June 30,2008



Some 24 hours ago, the phenom in a Filipino Fireball named Manny Pacquiao rendezvoused with history in an amazing fashion.

In a spectacle beamed to millions around the world, Pacquiao found his fourth world title – in the process annexing one more championship belt spread within the range of seven weight divisions. Stuffing fresh five pounds of additional firepower in his frame, Pacquiao in a masterpiece performance encapsulated the WBC 135-pound title belt (Sunday morning, Philippine Time), stopping and dethroning the erstwhile champion at Las Vegas’ Mandalay Bay Events Center.


Truly indeed, the fight saw both gladiators living up to their billings as ‘never-say-die’ brawlers. Both parties were industrious and relentless. And as work-rates constantly pumping into aggressive collisions, awesome blasts were heard in every tick of the fight - but alas, in a lopsided one!

Pacquiao did it with his revived signatures: blinding speed and power! At last, the world has witnessed the successful showcase of the long-overdue ‘Marco Bolo’ now performed to perfection inside the ring through countless gym rehearsals. And as envisioned, his opponent's chin did not last long. TKO in the ninth round! Referee Drakulich did not bother to count - as there will be no debate about it!

Pacquiao ended the carnage in the ninth round with a short - but devastating left that caught the durable champion on the chin sending him to the canvas in a loud thud, face down – ‘like sugarcane mowed down by an oversized sword’.


THE DANGEROUS DAVID DIAZ

The vanquished…? DDD – the “Dangerous David Diaz”!

DDD (now 34-2-1, 17 KO’s), in the aftermath of the bloody bout saw himself in deep cuts below his right eyebrow, his bridge of the nose oozing with coagulating fluids, eyes blackened & half-closed, lips swollen, in an entire facade of tormentous anguish.

Gracious however in defeat, the good-natured Diaz said: "Manny’s punches are just too fast. It was all his speed. He boxed much more than I thought he would."

"The cut didn't bother me," Diaz added. "But I thought he seemed to have a knife. It's like he was hitting me with a blade. What can I say? I lost today, I'll win tomorrow. To go like that with a guy like Manny Pacquiao, I think I'm doing pretty good."

Diaz had called the Sunday morning’s fight the biggest in his career. At $ 850,000, he was to receive the biggest paycheck so far in his lifetime. And winning this one would have been a big one. It would send him to the dreamland of the mega-bucked paradise. To David, Manny is his stepping stone, yet the Pacman could also be his stumbling block. A loss would be: quo vadis…, tu hombre?

But why not..? Ballooning with 29 pounds more cargo towards north, Pacquiao (now 47-3-2, 36 KO’s) started his pro career very light at 106 lbs as a lowly flyweight. On the other hand, Diaz launched his line of business heavy at light-welterweight and went south to lightweight where he found his championship.

Like Ortiz against Elorde, that supposedly meant he would be able to take Manny’s punches.

David’s an inside fighter – we all knew it.

His style is to crowd his opponent and the fight plan as I assumed, would be to rough up & bulldoze Pacman to the ropes and gain mental & physical advantage. Because he is physically bigger, I would like to think, ‘never mind two or three blows from the Pacman but a single blow of his own would be enough for Pacman to think twice’. Comes the ending rounds, as Pacman begins to lose steam…, that would be it – and it should be David’s sweet time! But alas … sorry, it did not come…

Truth to tell, my circle of friends after three rounds watching the fight, joked about that David Diaz must have planned as his defense to block Manny’s fists with his own face. It turned out that David himself did really make such a joke. In an internet article today, it says about David’s ‘strategy’ in combating Manny’s best weapon: “I think the best thing I can do is to meet his left hand with my face”, David as quoted. Of course it was a joke, but the ‘strategy’ was only half anticipated – because not only the left hands were coming in but also the blinding rights that made his swelling left cheek purple.

But then again, why not...? He had been successful before with title contender, Armando Sta. Cruz when far behind on points, he stopped Sta. Cruz in the ending rounds? It made him the Champion, wasn’t it? With Erik Morales, wasn’t his heart & industriousness in a full 12 round span did it? Stamina and work rate - aren’t they his best trademarks?

But then, with the Pacman as opponent, the 'bubble of durability' in David Diaz quickly burst right there & then at the very opening round!


THE FLAWLESS EXECUTION

Trainer Freddie Roach was noticeably pleased of the outcome. "He boxed better than he ever has. It was beautiful! We told him not to stand and trade in front of this guy, because David’s too dangerous”.

“We knew David Diaz was a strong guy. If we landed the combinations with Manny’s speed we knew we would out-speed him, but if we stood there and traded with him we would give him a chance to win the fight. The thing was not to step straight back but to step off to the side and then to turn him into another combination. And, it worked. We worked really hard in the gym and I am so proud of Manny’s right hand tonight. Diaz was looking for the left hand and the right hand was there all night long.”

Roach’s game plan worked perfectly as Pacquiao landed somewhat a one-sided ratio of 2.6 punches to 1. CompuBox statistics show Pacquiao's 230 stingers landing its mark out of 788 punches thrown, 180 of which were power punches. On the other hand, the confused Diaz only landed a dismal 90 out of only 463 throws. This translates into Pacman hitting Diaz 8.77 blows per minute in contrast to David’s 3.43 punches per minute.

Compare that to Pacman-Marquez II, in full 12 rounds, Pacman threw 619 blows while Marquez at 511. Pacman connected 157 punches (4.36 per minute) while Marquez at 172 (4.78 per minute). From the looks of it, "The Unfinished Business" was totally a different texture of a fight!

This time with Diaz, the Pacman circled around, jabbed and displayed an incredible arsenal of punches – a new manifestation of his being a complete fighter.

Unscathed, the Pacman hopped in and dished out three- and four-punch lethal combinations at a time, before quickly stepping out to recycle a recurring hurricane. Now a two-fisted warrior, Manny dominated Diaz with his right hand - throwing accurate & blinding jabs at will, the uppercuts, and the counter right hooks that couldn’t seem to miss its target in the whole 8-¾ round episode. After a few rounds, it then became clear that David Diaz was the perfect fighter for Manny to test the waters in his lightweight debut. As the fight progressed, Diaz launched punches with increasing frustration - frequently missing his eely opponent.

In his supremacy, Pacquiao won every canto on all three scorecards (by the way, mine included), with the scores at the end of the 8th reading 80-71 by two judges and 80-72 by one judge in his favor. Two judges must have scored a round with a 10-8. To compare, mine was a conservative 80-72.


A FOOTNOTE IN HISTORY

Before the June 29 date, the Pacman who started his pro career in 1995 as a 106 pounder had officially to his credit annexed three alphabet world titles. First was the WBC Flyweight (112 lbs), Manny then bypassed the Superfly and Bantamweight divisions to claim his second world title, the IBF Super Bantamweight Belt (122 lbs). Just last March 2008, Pacquiao grabbed the WBC Junior Lightweight Title (130 lbs) when he outpointed Juan Manuel Marquez.

It could have been four titles (and now should have been his fifth), if the featherweight (126 lbs) Ring Magazine’s Peoples’ Champion has to be included, when he knocked out then lineal champion Marco Antonio Barrera in 2003.

To recall, Pacquiao’s lightweight debut was filled with eyebrow–raising doubts. In my last article, I asked, “Can the Pacman withstand the blows of a lightweight/welterweight? On the other hand, can the power of a super-featherweight jolt a much-bigger opponent? Or, moving up in weight - an advantage or disadvantage?”

But all questions & apprehensions by critics including me have now been proven wrong and thus erased to naught. Pacquiao was too superior, too quick for Diaz. Using his newly mastered boxing skills, Manny dominated the much-bigger American in his own territory. But to me, David's loss to Manny is something not to be ashamed of. He has just shown the gallantry and serious fighting attitude only found in few boxers, these days.


CLOSURE

DDD, “Dangerous David Diaz” after all, as Bro Noel’s Brod Cesar said, DDD actually means now as, “Dangerous Dili Diay”… at least if Manny is the opponent.

To “Big Bro” Noel Fernandez of EAUC, “Brother Ely” of PEPSCOR, Jun, the “Erik Morales” Leyteno (este, not Latino) copycat, Cesar, (by the way, not the Fil-Jap mestizo) but the brother of Noel, to Loyde & Francis and to all others sharing with me in the live coverage; we all agreed that Pacquiao definitely is now a compleat skilled fighter. With his legendary speed, power, heart and stamina and now a new-found mastery of defense, we would like to think that Manny is invincible in his new found home at 135 lbs.

Valero? Campbell, Casamayor? Without doubt, I would root 150% for the Pacman – whatever happens!

But with Juan Manuel Marquez, it remains to be seen. I have the feeling just as I’m afraid; JMM is Pacman’s kryptonite. But if Pacman trains seriously at 135, there’s no way that Marquez can overpower Pacquiao.

Hatton? Ah, later… he can wait! That to me is retirement time with 20 million green bucks hanging on the line, just as Mayweather did!

LETHAL COMBINATION - PART I

LETHAL COMBINATION –
PART I

by Doods A. Amora, PEE



In an environment of sanctioned violence, the Pacquiao-Diaz banner on June 29, 2008 (Philippine Time) is promising a feast on the gushing crimson fluid - to the pleasure of the bloodthirsty in boxing.

Incidentally, both are ‘never-say-die’ brawlers. Both are industrious and relentless. With work-rates constantly pumping aggression from the two fighters, the match-up has all the makings of an awesome explosion.

What a classic fight it should be! That’s how the Pacquiao–Diaz encounter beckons from the horizon.


DAVID DIAZ:

Simply put, David Diaz (34-1-1, 17 KOs) is the current World Boxing Council’s (WBC) lightweight champion. But his crown is at stake – a threat not from an ordinary mortal but a risk from the most popular boxer in the planet today.

“I have been watching Pacquiao’s last fight with Marquez and his first fight with Morales on video and we think we see some things we can expose. If Manny comes at me all crazy and relentless, then I will get a little crazy too because I can get crazy myself”, David Diaz as quoted by the media.

Objectively, David Diaz is a legitimate champion in the 135 pound territory. However, during the time when the lightweight division was ruled by the Diazes, David was perceived as the least menace. Erik Morales himself wanted to prove it when he challenged David in his quest for a fourth world title. But then Morales was wrong when he failed his date with history. Although Erik had some good moments when he floored Diaz somewhere in the first round, but David’s uncompromising hard work overtook what could have been Erik’s sweetest winning moments. The fight, by twist of fate, proved otherwise as the greatest victory so far by David Diaz.

Of course, David’s knockdown by Erik had put to serious issue the integrity of David's chin. But then in boxing, no one knows when the miscues and flashes of fortunes ensue when two boxers mix it up inside the square arena. Bumping into a hard cracking counter right hand, David Diaz wobbled and was knocked down in a round which could have been his. Durable as he was though, despite the knockdown David labored bravely till the final round to win the bout convincingly. And his work-rate was the key. An incredible toil reflective of the heart of a warrior – indeed!

Aside from being a natural lightweight, David’s body is big & wide – and capable of inflicting injury to whoever clashing his way. Can the Pacman withstand the blows of a lightweight? On the other hand, can the power of a super-featherweight jolt a much-bigger opponent? Or, moving up in weight - an advantage or disadvantage?

Either way I believe anyway, but Flash Elorde failed in his time. Can the Pacman succeed where Elorde failed? As anybody might have surmised today, Elorde in his own battle with Ortiz needed to work doubly hard as his power could be absorbed by the bigger opponent. But then there are limits as to one’s capacity. The Flash had to yield to reality – not once but twice, if my memory serves me right.

Beating a ‘smaller guy’ in Manny Pacquiao must have been a motivation to the psyche of Diaz. But Manny just recently had been quoted by the media, saying: “I don’t believe Diaz is stronger than me. I believe I am stronger than him. Moving up in weight is not a problem for me because I will maintain my speed and power.”

“I am doing well in training because I can eat more than when I was trying to make 130 pounds. I feel very good. I like to eat rice and vegetables when I am training. In the past when I was trying to make 130 pounds I was tired from not eating, and I felt less powerful. Now that I can eat a bit more I feel I have more energy.”
This definitely is something Diaz has to worry.

But then, basing on the recent Diaz-Montano fight, many observers believe that David is not even near to Manny’s level. He is a slugger, always in front of his opponent, throwing punches endlessly but at the same time, absorbing blows in such a style that is ironically best suited to the hurricane combinations of the Pacman.

Will Lady Luck be with him this time? Let’s see…


MANNY PACQUIAO:

On the other hand, the challenger in Pacquiao (46-3-2, 34 KOs) who started his career as a 107 pounder will be testing the waters of an uncharted terrain at 135. Fresh from his recent crowning by the Ring Magazine as the world’s best pound-for-pound fighter, Pacquaio (just like Morales) aimed at special history to be the first Asian to win four world titles in four weight categories. And that’s not the end of the quest for more glory – the Pacman had already trained his sight to fight Hatton in a much-heavier division.

Is Pacquaio looking past Diaz? From the looks of it, it is. Wrong self-hypnosis...? Maybe yes, maybe not….

But whether or not Pacman can deliver another expectacular performance, this time and for the first time in the 135 pound class is the question.

What goes up, must come down. No Manny, not this time, please. But it seems that boxing enthusiasts are now in the belief that Manny’s phenomenal boxing career is on the downtrend basing on that rematch with Marco Antonio Barrera. Add to the list Pacquiao’s latest performance in the rematch against Juan Manuel Marquez in Unfinished Business II. As I wrote in my previous article; Marquez to me, won that fight! And I’m not posed to retract it.

Manny Pacquaio is now the WBC and Ring Magazine Super Featherweight Champion – the very titles he grabbed from Juan Manuel Marquez. But many of Pacman’s fans are concerned about the prize, if not, the hazards of being a superstar. Superstardom carries with it the swelling but intoxicating benefits arising from success. He is no longer as hungry as before as thought by many. Now super-rich, Pacquiao is seemingly the busiest celebrity and sportsman in-between fights. Probably preserving his multi-million assets, the Pacman, far from his usual signature, is now perceived as no longer exciting.

While Diaz did not stop his training regimen after the Montano fight, Manny reported for work late – to the displeasure of Freddie Roach. Has Pacman’s richness brought him to lethargy? Or is it over-confidence?

Maybe yes, maybe not… But then it happened in the Larios fight! Remember that scary third round? And who was Larios, by the way? Sad to say, Chololo was not in the company of Pacman’s class! Yet he almost ended the battle early.

In a more recent scene of the Unfinished Business II, Pacman had two months preparation, but Marquez had three full months. Nobody thought Marquez would last the distance, but Marquez showed the savvy of a world-class fighter that he is.


WHAT WILL HAPPEN:

When these two aggressive warriors collide, expect a loud blast. Pacquiao is known for his jaw-shattering punch carried-out in blinding speed and power. I can now visualize a perfect showcase of the secret ‘Marco Bolo’ technique which failed to appear in both the Pacman-Barrera II and Pacman-Marquez II. Moreover, David’s questionable defense is not known for counter-punching proficiency. I think Diaz’s chin would not last long. KO in the middle rounds! And there will be no debate about it.

However, if the bout goes the full distance, the effects of the natural weights will prevail. So with the effects of over-confidence on the part of Pacquiao!
Work, work & work! That’s the Diaz trademark. With stamina derived from focused training and conditioning, Diaz will be glorified by a split decision.

Diaz will then join in the mega-bucks rank. That’s the best guess I can make.

UNDERSTANDING MAINTENANCE

UNDERSTANDING MAINTENANCE
by Doods A. Amora, PEE

In any facets in life, there is always what we call as “desired condition”. And Performance Standards have always been derived from these “desired conditions”...

Performance Standards of machines as goals in maintenance are often based on the workings of things when they are still brand new. In other words, it is often desired that performance of anything (capacity, process capability, efficiency, throughput, etc) must not degenerate in the entire lifetime of the machine. But reality is that there is always an end to any lifetime and that the likelihood of deterioration increases with age.








Hence, we need maintenance engineering in the plant. Maintenance is actually making plant facilities and production lines operate at acceptable levels for a long period of time - even surpassing people’s lives. Given a nice-looking new industrial plant without maintenance and the plant will crumble in just a few years. But then, there are industries that last for centuries! And there are machines that outlive generations.


MAINTENANCE – ‘A DIFFERENT THING TO DIFFERENT PEOPLE’

Maintenance, per se, did not change much. But approaches to its management had evolved significantly. For instance in today’s management concepts, the philosophy that “maintenance is 50% production job and production is 50% maintenance job” has now brought maintenance as a condition to production while conversely, production a condition to maintenance. Note that in the past, maintenance is merely seen as a “necessary evil service department” – not a condition to production.

Furthermore, implementation of maintenance differs. For instance, the British, Japanese, American, Swedish and Filipino styles of maintenance are not exactly in the same terms. Usually, a manufacturing concern tailor-fits its own maintenance system to the management philosophy of the business, to the culture of the people and the conditions prevailing the business environment. Thus, even in the modern times, according to notable experts, “the function of maintenance still means different things to different people” (John Peter Koss, Beverage World International, Feb. 1999 issue).

A Large Maintenance Shop (picture courtesy of the Internet)

A Just-In-Time (JIT) type of maintenance may fit the Japanese environment, but might not be ideal to Philippine conditions. Japanese JIT-practicing companies do not believe in stocking spare parts (cost of space in Japan is very prohibitive) but then, their parts suppliers or manufacturers are just next door. They order now through computer links and the spare parts are there in minutes! In the Philippines, it might take 6 months. JIT means just-in-time in Japan. In the Philippines, it means, “almost late…?"

On the other hand, the concept of Corrective Maintenance was previously defined by practitioners as, emergency maintenance. Arguably, to other practitioners this may not be exactly true today because corrective maintenance can also be planned. Corrective Maintenance covers all maintenance activities carried out to correct or repair a fault in the equipment. The above statement says that as long as the activity needs repair, it is classified as, corrective. A timely changing of car engine oil for having just about losing its correct properties after an inspection is in fact, correcting a fault. But this correction of fault is not an emergency situation because the breakdown has yet to happen. Corrective maintenance therefore can be both preventive and breakdown maintenance.


IMPLEMENTING MAINTENANCE

To implement a maintenance system for a plant, all personnel without exception - from the top managers, production personnel, maintenance practitioners to the last janitor, must speak in the same language. It is therefore necessary to go through how different maintenance practices are defined in any plant context and application.

The term maintenance is defined as:

“Maintenance covers all activities undertaken to keep equipment, machineries & facilities in a desired state or condition to include all other services done to return the equipment or facilities back to that desired condition.”

IEEE on the other hand, defines maintenance as: “The act of preserving or keeping in existence those conditions that are necessary in order for equipment to operate as it was originally intended”.

There are two general classification of maintenance: :

* Breakdown Maintenance (BDM)
* Preventive Maintenance (PM)



BREAKDOWN MAINTENANCE

Breakdown Maintenance (BDM’s) are maintenance services carried out to bring a faulted equipment or machine back to its productive state.

Tell tale signs of breakdown maintenance are the following: a) emergency activity, b) unplanned services, c) production stoppages, d) lost production opportunities, e) large product rejects, f) fighting fires, g) costly.

In this mode, there must be equipment breakdowns to fix - or fires to put out. In other words, breakdowns in a production plant are states of emergencies. And no management wants a series of emergencies in the plant.


PREVENTIVE MAINTENANCE

Maintenance practitioners declare that the best maintenance must be the preventive & proactive one. Breakdown maintenance is fighting fires and therefore not desirable. In agreement, maintenance managers say that “an ounce of prevention is much better than a ton of cure”. Breakdowns are always costly – not only on the physical damage of the machine but on the cost of lost opportunity.

Preventive Maintenance (PM) is defined as maintenance activities that cover all programmed services carried out to control deteriorating conditions that lead to the occurrence of failures. These activities must be performed before these deteriorating conditions develop into a breakdown or disturbance in production. Note that a maintenance activity can only be PM if it is programmed or planned. This means that PM’s are services decided in advance.

The practice of Preventive Maintenance can be further classified as:

1) Time - Based Maintenance (TBM
2) Condition - Based Maintenance (CBM)
3) Improvement Maintenance (IPM)

Time-Based Maintenance (TBM):

* regular, periodic, cyclic as attributes
* having fixed-time frequency (daily, weekly, monthly, yearly …)
* usage-based activities (running hrs, flying hrs, mileage …)

Condition-Based Maintenance (CBM):

* services that follow after tests & measurements
* planned correction of a certain condition
* services resulting from condition monitoring
* planned & programmed

Improvement Maintenance (IPM):

* redesigns to improve equipment performance
* environmental controls & improvements
* systems improvements

In real life, Preventive Maintenance can be a combination of TBM’s, UBM’s CBM’s and IPM’s. In advance countries today, Condition-Based Maintenance (CBM), also called Planned Corrective Maintenance (PCM) is the one identified as the most cost-effective type of maintenance. It becomes too expensive to replace spare parts just because it reaches the scheduled frequency. With condition monitoring activities made regular, “touching a running machine” becomes justifiable only when the condition of the machine is the one calling for it. But effective surveillance to these abnormalities is the key. Abnormalities must be detected before they develop into full-grown failures. Thus, surveillance on the health of the equipment is what we refer to as Condition Monitoring.

Improvement Maintenance (IPM) in Japan is termed as "Maintenance Prevention" or ‘MP’. Some other literatures call it “Design-Out Maintenance”. Modifications into the machine itself or making changes in the system or environment are common scenes in IPM. Enclosing and providing air-conditioning to a high tech control centre full of electronics components to manage environmental conditions as dust intrusion, humidity and temperature inconsistencies are examples of IPM. To operate a control centre heavy in electronics components without environmental control is facing everyday troubles & breakdowns. Providing it with the right environment to free up these pestering troubles is Improvement Maintenance.


CONDITION MONITORING

Condition-Based Maintenance or the so-called Planned Corrective Maintenance can not succeed without Condition Monitoring. Practitioners of modern-day maintenance systems discovered that most machine failures do have the so-called FDT or “Failure Development Time”. If most failures have to undergo FDT’s (as in most mechanical & electrical equipment) before actual seizures, then these failures can be detected in advance through Condition Monitoring. Results of condition monitoring will trigger implementation of Condition-Based Maintenance (CBM's) or Planned Corrective Maintenance (PCM) in the first window of opportunity to do so. With advance diagnostic instruments & testing equipment, other practitioners refer these activities as Predictive Maintenance.







Condition Monitoring leading to Predictive Maintenance services can be done in four (4) different ways:

* Subjective Condition Monitoring
* Objective Condition Monitoring
* Continuous Condition
* Statistical Process Control

Subjective Condition Monitoring are regular surveillance activities on the health of equipment and machines by means of human senses (sight, smell, touch, taste, hearing and “the sixth” sense). Being the first line of defense against deterioration, it is the domain and responsibility of the operators.

This type of condition monitoring is putting great demands on the individuals performing the activity. However, experience of the operators & technicians on the operating behavior of their machines internalized over the years is a wealth of expertise that can not be under-estimated. The Taong-Bahay or the car driver normally knows what’s happening to his ward if there is a shift in performance. The awesome resources of our operators are just there waiting to be tapped. Even in advanced countries, 70% to 80% of condition monitoring is done subjectively.

Objective Condition Monitoring is when the condition of the machine is being determined with the aid of portable diagnostic instruments. State-of-the-art diagnostic instruments may be in the form of photo-thermal, vibration-based, ultrasonic, laser-based, temperature-based, shock pulse, infrared scans, or electronics-processing techniques that could provide timely information on the integrity of the equipment in relation to failure modes. Overheating, leaks, joints & weldment failures, insulation deterioration, moisture intrusion, cracks, excessive vibration, bearing condition, material wear and many more failure modes can be detected in advance while they are still undergoing FDT’s. Again, other practitioners call them, Predictive Maintenance.

Continuous Condition Monitoring is a form of a self-diagnostic objective condition monitoring, but in this case, instruments are attached permanently in the machine and their sensors imbedded or built-in the machine system. Normally computer-based, the system gives out alarms and automatically prints-out schedule for its maintenance should an operating parameter is nearing to or beyond specified limits. This needs large investments that require a careful study on the benefits of this technique to justify the capital outlay. Even in highly industrialized countries, condition monitoring is 75% subjective, 20% objective and 5% continuous. Unless the equipment in question is very vital, dangerous and exceedingly expensive as in nuclear plants, large turbines or steel mills; “continuous condition monitoring" may not be justifiable. But as technology becoming cheaper, new generation diesel power plants are now sporting this type of condition monitoring and their number is increasing.

Statistical Process Control: The increasing popularity of the practice of Statistical Process Control (SPC) where quality monitoring of the product output of the machine is a built-in process, has paved the way for a more reliable monitoring of the equipment. A variation of the quality of the output product means a questionable process capability of the machine. A questionable process capability means that there’s something wrong in the machine. Any significant variation of product quality therefore means an immediate requirement for maintenance services.


“IF AIN’T BROKE, DON’T FIX IT”

It is worthwhile to mention that many maintenance practitioners believe that PM is to take out the equipment from operation after a certain time interval for disassembling and replacement of large number of parts, as what old plant engineering handbooks had recommended. Experience showed that when the equipment is re-assembled and brought back to operation, problems oftentimes occur because the repairmen had transferred faults into the equipment. In modern maintenance management, PM is something more than disassembling and changing of parts. MGruppen Consultants of Sweden left us with a saying: “NEVER TOUCH A RUNNING MACHINE”. Same way that Americans say, “IF AIN’T BROKE, DON’T FIX IT”. This means that teardowns could only be done if there’s strong reason to do it. And that strong reason must be established first.

How? Through Condition Monitoring leading to Condition-Based Maintenance services…
