Accendo Weekly Update #360
A new course
by Ray Harkins
In this course, “An Introduction to Quality Engineering”, you will gain a thorough and practical overview of the quality profession without getting bogged down in technical jargon. You will not only learn about the 12 KEY AREAS of quality engineering but also gain practical concepts in each.
The links to the course here and on the site contain a code for an exclusive Accendo Reliability discount - which is good till October 20th.
Announcements & Reminders
Ray also writes articles in The Manufacturing Academy plus has a few other courses available that may be of interest.
Reliability Engineering Statistics, An Introduction to Reliability Engineering, Process Capability Analysis, Root Cause Analysis and the 8D Corrective Action Process, and Return on Investment (ROI) Analysis for Manufacturing
Ray hosts the courses on Coursera and using one of our links provides a small referral fee back to Accendo Reliability, which is most appreciated.
Stay safe, stay flexible, and stay resilient.
Cheers,
Fred

Chris and Fred discuss how we create a ‘reliability plan.’ It is not simply a list of tools.
Greg and Fred discuss the concepts and words surrounding reliability management, risk management and enterprise risk management.
Dianna talks about what type of information we can gather and a stepwise approach to get it with our cross-functional team.
Join Andrew and Ryan for a revealing conversation about how to democratize innovation in asset-intensive industries and learn how you too can take part in creating waves of change.
Mike and his guest, Ed Stone, review some of the equipment options for low-volume SMT production and see if the barrier to entry for in-house assembly is lower than one might think.
There always was and continues to be the challenge of protecting components from the dangers of static electricity. My guest today is Thomas Ricciardelli, Founder and CEO of SelecTech, a manufacturer of ESD flooring for the electronics assembly industry.

Some of you might have heard about probability plots … like Weibull plots. Some of you might not. A Weibull plot is a really useful way of quickly ‘looking’ at data and being able to ‘see’ really useful things. This could be seeing that the rate of failure of a system is decreasing over time … which usually means there are manufacturing defects. It could be seeing that the rate of failure of a system is increasing over time … which means the system is accumulating damage or wearing out. And lots of other things. So let’s look at a different sort of ‘probability’ plot … and see what we can work out from it.

What is it that makes the difference between good and great related to reliability engineers? What is the magic element that separates those that can carry out tasks such as facilitating an FMEA or designing and analyzing an ALT from those that impact an organization’s culture? A good impact that improves the organization’s ability to create reliable products.

If you have spent any amount of time doing reliability engineering stuff, you will probably have heard of this thing called a ‘fault tree.’ You may have even used fault trees a lot. But it is amazing how many different reliability engineers have different ideas about how to best use a fault tree. Some think fault trees are strictly used to work out which combinations of components need to fail in order for the system to fail (system reliability modelling). Others think fault trees are really useful for helping us work out what the causes of failure are (root cause analysis). Both people are right. So why do we get these competing schools of thought? Join us for this webinar to learn more about how fault trees can help you … regardless of what you are trying to achieve.

In my opinion, as I do not know if this is true or not, every product or system failure has a cause. Causes are not exactly the same as what we call ‘failure mechanisms’, yet they are related in many cases. One more term to consider is ‘failure mode’ which is the symptoms or results of a failure.
Let’s focus on failure mechanisms in the discussion. During design, manufacturing, and use it is the mechanism information that we can use. We can design out failure mechanisms, minimize introducing them, and delay occurrence via maintenance. For a failure analysis to succeed we need to understand the mechanism(s) at play well to move forward. To design an effective screening test or accelerated life test, we need to know the mechanism(s) involved.
It may be safe to say, failure mechanisms are at the heart of much of what we do in reliability engineering. Let’s explore the many ways something can fail and how understanding failure mechanisms makes a difference.

BLEVE stands for Boiling Liquid Expanding Vapor Explosion
If a tank containing liquid is subjected to external fire, the heat from the fire lead to boiling of the liquid. This in turn leads to increased pressure in the tank. This “boiling” liquid and “expanding” vapor may increase the pressure significantly and cause the tank to rupture. If the released liquid is flammable , it can catch on fire resulting in a fire and explosion. ...[Read more…]
Fatigue cracks that originate at inclusions. Stainless steel intergranular corrosion due to chromium carbide precipitates. Low steel toughness because martensite not tempered enough. Low aluminum strength because of excessive grain boundary precipitation. Orange peel due to large grains.
These are examples of how problems with a metal’s microstructure lead to reliability and performance problems. ...[Read more…]

As you do the Maintenance Planning role remember that you are part of a business that wants to build a great company. Maintenance Planning is a foundation requirement to ensure maintenance work is done successfully, right first time. A Maintenance Planner’s role is to prepare work packs in a timely manner for the effective, efficient and safe performance of maintenance work. ...[Read more…]
I know. I’m a lady. But it’s not my expression. That’s what my mentor, John Moubray, called it.
And he didn’t apologize for it when he used exactly that term during a one-on-one mentoring session with me.
And to this day, it’s one of the most valuable (and profitable) lessons he ever taught me. ...[Read more…]
Which of these six failure rate functions do your products and their service parts have? You don’t know? You don’t have field reliability lifetime data by product name or part serial number? That’s OK. Lifetime data are not required to estimate and classify failure-rate functions, including attrition and retirement. GAAP requires statistically sufficient field reliability data to classify failure rate functions for RCM. ...[Read more…]
Production processes come to a grinding halt when equipment breaks down. This results in production delays, costs incurred to fix the machine, and opportunity costs. The production process cannot proceed until the maintenance activity on the faulty machine is complete — unless you have provisioned equipment redundancy. ...[Read more…]
