MC 012 Six-Sigma and Materials Engineering

Six-Sigma and Materials Engineering

In this episode I discuss 6-sigma, statistical process control, and the role of materials engineering in developing capable manufacturing processes.

Materials are used to fabricate components and join components together. And, we want manufacturing processes capable of producing components and assemblies without defects or problems, and whose materials have the desired properties. So, developing and maintaining a six-sigma manufacturing process depends heavily on materials engineering.

MC 010 A Different Perspective for Seeing Products

A Different Perspective for Seeing Products

How do you look at any product? See just a thing that performs a certain function? In this episode I discuss my perspective on how I see a product – as an assembly of materials – and how it influences how I help design products to meet performance, reliability, and cost goals.

He’s wrote a book – Materials Enabled Designs. It teaches how to select materials that optimize product performance, reliability, and cost.

MC 009 Learning and Professional Development

Learning and Professional Development

In this episode I discuss learning and professional development. There’s so much to know to be an engineer and college courses cover the tip of the iceberg, even if you go to grad school. I learned this early in my career as I was faced with decisions and problems related to topics that I never encountered in school. I also learned that I had to shoulder the responsibility of learning the topics. Some of the learning came from colleagues, some came from taking short courses, and some came from reading textbooks and technical journals. In this episode I discuss my learning experiences and philosophy about learning, the pitfalls of relying on learning just from experience, and resources for learning and professional development.

He’s wrote a book – Materials Enabled Designs. It teaches how to select materials that optimize product performance, reliability, and cost.

MC 008 Design for Manufacturability

Design for Manufacturability

In this episode I discuss Design for Manufacturability related to component fabrication and joining components by welding, brazing, or soldering. Design for manufacturing is concerned with designing components and assemblies that can be repeatedly produced with consistent good quality without hassles, and at low-cost. DFM applies to primary component fabrication processes, secondary processing (coating, heat treating), and joining. Primary component fabrication processes include casting, extruding, stamping and other cold forming, forging, and machining. Secondary processes include heat treating, machining, and coating by painting, electroplating, anodizing and other processes. And joining includes welding, brazing, soldering, and using adhesives.

He’s wrote a book – Materials Enabled Designs. It teaches how to select materials that optimize product performance, reliability, and cost.

MC 007 Failure Analysis of Component Failures and Manufacturing Problems

Failure Analysis of Component Failures and Manufacturing Problems

In this episode I discuss failure analysis component or joint failures during product testing or use and manufacturing problems such as supplier quality problems and manufacturing output that doesn’t meet specifications.

Failure analysis is part of performing a root cause analysis to identify the action, event, or decision that led to a component failing in a product or led to a manufacturing problem. The information from a root cause analysis is used to either fix a problem – in the case of product design and manufacturing – or assign blame – in the case of an insurance claim or litigation.

He’s wrote a book – Materials Enabled Designs. It teaches how to select materials that optimize product performance, reliability, and cost.

MC 006 You Have to Think Small to Understand Metallurgy

You Have to Think Small to Understand Metallurgy

(Apologies up front – I recorded this episode using the wrong microphone. So, the sound quality is fair. I’ll do better next time.)

There are microscopic structures and processes in metals that have large effects on metal properties, performance, and reliability. Being able to conceptualize these structures and processes goes a long way toward understanding the behavior of metals and the effects of mechanical processing and heat treating on metal properties. In this episode I discuss some of the microscopic structures and their effects on metal properties.

I also discuss recent projects and a bonus at the end – some details about my recent trip to Seward, Alaska

He’s wrote a book – Materials Enabled Designs. It teaches how to select materials that optimize product performance, reliability, and cost.

MC 005 Metals Engineering Perspective to Component Design

Metals Engineering Perspective to Component Design

In this episode Michael discusses the metals engineering perspective to component design. The concepts actually apply to all materials – metals, polymer, ceramics, and new classes of materials.

No matter the application, the considerations when designing a component are always the same. It’s necessary to understand all the design requirements when selecting materials and finalizing a component’s shape and features. The design requirements include performance, reliability, weight, cost, how the component will be fabricated, and how it will be joined to other components. With this information it’s possible to identify alloys and make changes to the component’s shape and features as needed to meet the design requirements at low-cost. Often, trade-offs between component materials and form are made to optimize the design. This is especially important for design for manufacturability to keep costs down and ensure a receptive supply base.
