Helping Products Survive Transportation
podcast episode with speaker Fred Schenkelberg
Besides building your product inside your customer’s facility, your product will require some form of transportation to move from your factory to your customer. When your product doesn’t work ‘out of the box’, that is considered ‘not good’ for customer satisfaction.
270 – Where to Start with DfM & DfR with Fred Schenkelberg
Welcome Fred back to the podcast. Clients are starting to realize that they have to design their systems properly while paying attention to certain tradeoffs. However, tell us where they should start; whether to design for reliability or maintainability.
Before starting, the team has to look at their business goals and decide whether the acquisition of any system or a piece of equipment assists to that end. It has to be a business decision.
Pay attention to:
- The environment of usage
- The cost of ownership; is it going to be profitable?
- The usage rate of the tool
- Type and quality of the tool
In this episode we covered:
- Understanding the tradeoffs is essential while keeping the important things in mind. Where do we place time and resources? Reliability or maintainability?
- Once they have chosen to rely on data and experience? Where do they start in designing for maintenance or reliability?
- Create basic standards. Otherwise, the advanced things like the right model shall not matter. Basic aspects such as a complete bill of material that can be uploaded on to the CMMS, documentation should be taken into account.
Fundamentals of Stress-Strength Analysis
If your product is stronger than the applied stress, it should work. The stress/strength relationship concept is well known, but did you know stress and strength change over time? Let’s use the best information and tools for this analysis. [Read more…]
Process Capability, Tolerance, and Reliability
Product failures may occur due to material or component variability. The steel in a bracket is more brittle than optimal, or the capacitance is on the low side of an acceptable range. Designing a product with variation in mind enables the creation of a reliable product. [Read more…]
Creating Meaningful Reliability Predictions
Early and often during product development, the team needs to know the expected reliability performance of the current design. The values provide information to make decisions.
We can create meaningful estimates. Or not.
Reliability and Tolerance Analysis
A tolerance specification is how we communicate the allowance for part variation.
Variation happens, and when it is within what we expect, great. Otherwise, quality and reliability issues ensue. Let’s explore how to set tolerances to improve reliability properly.
Let’s understand the process data, stability, and design constraints in an attempt to find a balance to create meaningful tolerances.
