In past articles, we have explored the basics of Erosion, Corrosion, Fatigue and Overload. Our emphasis has been on creating an awareness and appreciation for the value of failed components, to any investigation.

In this article we are going to delve into Fatigue a little bit more (because it is the most common fracture pattern) and see how we can use an evidence-based, deductive logic process to determine what elements of Fatigue may have been at play. We are trying to create an intellectual curiosity within the front lines about ‘making the call’…is it Fatigue, or some other fracture pattern?

The 15 things your new “Smart Machine” won’t tell you.

The 15 things your new “Smart Machine” won’t tell you.

1. It won’t tell you that someone failed to lubricate it

2. It won’t tell you that they put the wrong type in

3. It won’t tell you if they under filled it or overfilled it

What is Precision Maintenance?

Precision Maintenance May Be The Key To Unlocking Reliability

Why is it that some individuals perform a PM Routine and always find something and others don’t? And why is that when some individuals perform a rebuild or overhaul, the equipment struggles to start and return to steady state? The answer comes down to how detailed the individuals are during the maintenance activity. But how can this be overcome with such a wide range of individuals in the maintenance team? The answer is precision maintenance [Read more…]

The “new normal” can be much better

The “new normal” can be much better if we choose. Why go back to the same-old, same-old?

As we emerge from the 2020 pandemic and all the measures to contain it, your workforce will be returning to a “new normal”. What’s that? None of us really knows the details, but aside from being a cool phrase, it means being smarter and doing things differently with a great deal of awareness about disease transmission. Keeping our distance, wearing masks when ill, avoiding crowded venues, and patiently waiting for vaccines, will be a part of it, but what else will characterize the “new normal”?

Deeper Dive into AMS

This video provides a more in depth understanding of Asset Management Systems.

Questions About Coefficient of Friction in Fasteners

I recently received an interesting LI inquiry that I felt others could learn from the answers that I was able to get. This is not my expertise so I sought out answers from some colleagues who were more familiar with fasteners.

Here is the original inquiry (translated from Portuguese so I hope Google Translator did a good job):

“I would like to know if you can help me clarify my doubts about:

The purpose of conducting a study of the coefficients of friction in screws, threads and nuts?
Is there an accurate standard for such testing?
What methods can be perfected in projects that target this type of trial and application?
Can surface treatments influence changes in results?
Who is responsible for such testing (the manufacturers and suppliers of raw materials, the assembler and/or its various final assembly applications)?

The Importance of Documentation in Precision Maintenance

Why Proper Documentation Will Lead to Sustainable Improvements

Imagine being able to look back and see what settings the equipment was last ran at for a particular SKU. Or being able to look back at the last three alignment inspections and see that slowly the alignment is drifting. What could you do with this type of information? You could perform Root Cause Analysis to see why the alignment is drifting, or trend the drifting to know when it will be out of acceptable tolerances.

Having the right information is critical to making informed decisions and driving systematic improvements in the performance of the equipment. This information is typically captured in a report or work order and should be linked to the asset and easily searchable. However, most organizations that I have worked with do not record the right information, which would allow them to make informed decisions. This documentation is a critical piece in precision maintenance, so what is required for documentation? [Read more…]

Maintenance and Reliability Maturity – 2

In part 1 of this 2 part series, “Maintenance and Reliability Maturity”, I point out that achieving the maximum value from your physical assets will require excellence in 2 main dimensions, efficiency, and effectiveness. Those are described more fully in our recent book, “Paying Your Way“. I also promised a Maintenance and Reliability Maturity Assessment tool. That tool is now available to you, our readers.

7 Steps of Clean, Inspect, & Lubricate

Through daily inspections, cleaning, and lubrication practices we can measure, prevent, and restore deterioration to our equipment. The expectation is that a team is put together made up of maintenance, operations, and leadership employees to roll out strategy beginning with one piece of equipment. They will implement the following 7 steps:

Initial Cleaning
Eliminate sources of dirt and hard to clean & inspect areas
Create and maintain cleaning, inspection and lubrication standards
General Inspection
Operator Inspection
Activities standardized
Team Development and Operator Driven Reliability

Recognizing Basic Gear Fatigue Failure Patterns

Lets start with a fresher on general Component Fatigue.

Fatigue occurs when a material is subjected to repeated loading and unloading.
When the loads are above a certain threshold, microscopic cracks will begin to form at a material’s surface.
Cracks always begin in high stressed areas of a material.
Eventually a crack will reach a critical size, and the structure will suddenly fracture.

Allowing Wrong To Become Normal

I’ve seen it twice this year and it concerns me. In twenty years of working with companies to improve manufacturing reliability I would like to believe that those of us who care are leaving a mark. It’s the days I’m about to describe that make you wonder.

I created RCM Blitz™ over twenty years ago as a tool that would help companies identify a complete maintenance strategy to improve and achieve the inherent designed reliability of their critical assets. Prior to entering the world of consulting, I had completed and implemented several RCM (Reliability Centered Maintenance) analyses on critical assets at Eastman Kodak company. With each analysis we completed, I gained knowledge and confidence that the process when adhered to and implemented, could improve the reliability of even our worst assets. In the same two years of proving the process I also learned something very important.

Learn to Speak Finance

The Key To Gaining The Ear Of Your Executives

As a maintenance professional, you spend a lot of time explaining how a proper maintenance & reliability program will improve uptime, safety, etc. But why is it that there is a hard time gaining support for the improvement initiatives? Well, senior executives are focused on how the company is being a measure of performance from the shareholders, financial analysts, or owners. Most of these measures are financial in nature, and while there are others, the primary measures are financial. [Read more…]

Maximizing the Potential of Your CMMS System

It’s no secret that equipment maintenance software offers many benefits to your organization. However, organizations frequently find that the software doesn’t deliver the end results they anticipated. This often happens because organizations don’t maximize CMMS potential. In other words—they’re not using their software to its fullest potential.

Maintenance and Reliability Maturity – 1

Maintenance and reliability maturity provides an understanding of both how well we do maintenance and how good is our maintenance program. One delivers a major business result, the other is a big part of how you get there. Doing maintenance with precision and care, so the job is done once and done well by the right people and without delay is what maintenance organizations strive for. Some achieve it, some struggle to do so. If they can achieve that, then they are being efficient.

Clean to Inspect for Best in Class Operator Care

Cleaning is an important first step in Operator Care and reliability gains because:

Insufficient cleaning causes losses and
The cleaning activity itself exposes hidden defects

Dirt in rotating parts, sliding parts, pneumatic and hydraulic systems, electrical and control systems, sensors, etc. causes malfunctions, reduce function, failure by wear, clogging, resistance, speed losses, etc. are different types of defects. Defects are anything that is abnormal from the expected ideal condition. Insufficient cleaning causes forced deterioration. All these losses are solved through a thorough cleaning of equipment and countermeasures to keep the equipment clean.
