We recently spoke with Ed Walsh, VP of Global Sales at Sigmetrix for an update on the company and its technologies. During the interview, he spoke how the company continues to be focused on helping customer design and build better products through mechanical variation management.
Sigmetrix is unique because it’s not just a software company, but also a service and training company that together provide a comprehensive solutions approach for its customers.
Sigmetrix is a company whose focus has always been on helping companies create better products through mechanical variation management.
Walsh said, “We can break mechanical variation management down into two parts. Better products would mean a product that’s safer, maybe more efficient, produces less pollution, and is more accurate. For us, that’s what better products mean. Variation is something that comes in and can make those products not so good. Maybe makes the product less competitive or makes customers less happy. So, we’re trying to manage that to make better products”.
“Our customers want to get the most out of their technology investments with the most efficient use of their resources. This includes things like having solutions that scale to multiple skill levels in an organization. We address this need by having our cornerstone tolerance analysis tool (CETOL 6 Sigma) that is used for advanced applications because it’s very powerful, but also a 1D tool (EZtol), that’s relatively simple to use. We are seeing an increased demand for tools that teach people geometric dimensioning and tolerancing (GD&T) as they use them by incorporating training solutions in all of our tools. We feel that that education helps establish a use case, or ability to be used, by that whole spectrum of users”.

What Does Mechanical Variation Management Mean?
Sigmetrix’s mission statement is “Better products through mechanical variation management.” We asked Walsh if he could elaborate on what that actually means.
“I think the way we can best describe it is by defining what variation actually is. Variation can represent any number of things between the viscosity of a fluid or the amount of flow through a circuit, just based on the random variation of how things work in the world, for example, weather”.

We recently interviewed Ed Walsh, VP of Global Sales at Sigmetrix for an update on the company, its technologies, and the state of the industry. Like our previous discussion, during the interview, he spoke how the company continues to be focused on helping customer design and build better products through mechanical variation management. “Sigmetrix is unique because it’s not just a software company, but also a service and training company that together provide a comprehensive solutions approach for our customers,” Walsh said.
When asked for a little background on himself and Sigmetrix, Walsh said, “Over the past 20+ years in the industry I’ve witnessed a need that customers have conveyed – they want to get the most out of their technology investments with the most efficient use of their resources. This includes things like having solutions that scale to multiple skill levels in an organization. We address this need by having our cornerstone tolerance analysis tool (CETOL 6 Sigma) that is used for advanced applications because it’s very powerful, but also a 1D tool (EZtol), that’s relatively simple to use. We are seeing an increased demand for tools that teach people geometric dimensioning and tolerancing (GD&T) as they use them by incorporating training solutions in all of our tools. We feel that that education helps establish a use case, or ability to be used, by that whole spectrum of users”.
Reflecting on his first job, Walsh said, “I worked for a company that was an OEM to heavy equipment manufacturers, such as John Deere, Caterpillar, Case, and New Holland. Mostly John Deere, but we also built operator enclosures for the other companies. The company I worked for itself had, up until me starting there, really did more contract manufacturing and not much design work. At that time, the engineers were doing design work on giant sheets of vellum and using pencils and manual drafting tools. I was part of the first dedicated team of designers using a very early version of Pro/ENGINEER. We were given a general idea for CAD with functional requirements, but no design parameters”.

“The great part for me was that I had the ability to go out to the pattern maker that was right next to our CAD workstations and say, ‘Hey, I want to make something like this’, and they could mock it up, and I could see how the parts were fitting together and where are they going to fit, and did it make sense from functional and manufacturing standpoints. If we needed something bigger, we could go down to the production line, but it gave me a really good idea of what actually was happening once the design concept left my CAD station. Overall, it was a really good experience for me”.

Since in-person trade shows and interviews are not possible right now and into the foreseeable future, via Zoom we recently interviewed Ed Walsh, VP of Global Sales at Sigmetrix. During the interview, he spoke about how the company is focused on helping customers design and build better products through mechanical variation management. “We’re unique because Sigmetrix is a software company, a service company, and a training company that together provide a solutions approach for our customers,” Walsh said.
When asked for a little background on himself and Sigmetrix, Walsh said, “I’ve been with Sigmetrix for 14 years, and have been in this industry for over 20. Over that time, I’ve witnessed a need that customers are starting to convey – they want to get the most out of their technology investments with the most efficient use of their resources. This includes things like having solutions that scale to multiple skill levels in an organization. We address this need by having our cornerstone tolerance analysis tool (CETOL 6 Sigma) that is used for advanced applications because it’s very powerful, but also a 1D tool (EZtol), that’s relatively simple to use. We are seeing an increased demand for tools that teach people geometric dimensioning and tolerancing (GD&T) as they use them by incorporating training solutions in all of our tools. We feel that that education helps establish a use case, or ability to be used, by that whole spectrum of users”.
“Because too much confidence is often placed in 3D models alone, we also see that customers want a tool that can be used in the multiple stages of the product development process. For example, traditionally, tolerance stack-up was done at the end of the design process just before it went into production. It was more of a validation tool, whether they were using spreadsheets or other tools”.
“If I look at the best of our customers versus the rest of our customers, just like most other simulation tools, they’ve shifted it earlier into the product development process, into the concept, and even R&D stages, to get an order of magnitude, a ‘what if’ type of analysis, on what’s better and what’s not. Our CETOL tool would be an example where people have shifted that usage. Customers also want to have decision-making from these analysis tools that can be addressed by multiple tiers of accountability in an organization”.

Making the Case for GD&T and Tolerance Analysis
While Sigmetrix considers itself a niche company for GD&T and tolerance analysis and mechanical variation management, it is a very important niche that goes well beyond product validation and can be applied in all phases of development, design, and inspection that can help customers make better decisions to ensure meeting their product requirements.
