About Dimensional Control Systems

With more than 20 years of providing quality SPC and tolerance analysis solutions to manufacturers, DCS has been influential in helping manufacturers reduce their Cost of Quality

Delivering Leading Quality Technology Since 1994

Beginning in 1994, DCS has been developing dimensional engineering and quality tools for manufacturers. With its start as an Engineering Service Provider, DCS has helped companies execute dimensional engineering to improve quality and reduce costs. 



DCS was established by Robert Kaphengst and John Mathieson to support the need for a disciplined approach to GD&T deployment. This approach would come to be known as the Dimensional Engineering Process. The first DCS customers were automotive OEM’s and suppliers needing to apply this discipline to their engineering organizations.

Vice President, Product Engineering Software, Siemens PLM Software

In a typical section of an A320 Family Aircraft, roughly 90 stringer couplings are installed. Around 2/3 can be covered with the parametric model (this equals 60...couplings.

In the A319, A320 there are 4 section joints, while the A321 has 6. One parametrical model can then cover 180 assembly situations.

Successful tolerance analysis product execution played a major role in our achievement of high quality across our product vehicle line. The Chevrolet Volt, Chevrolet Silverado, Chevrolet Malibu and Cadillac CTS were all named Car/Truck of the Year winners.

General Motors

By being able to do very comprehensive modeling, the other advantages we’ve seen is we’ve discovered sensitivities in areas we wouldn’t have expected you know well outside our region of interest that had influence, it’s also served as a quality check for our drafting process as well as allowing us to incorporate feedback from the manufacturing floor.  

Avery M.

Design Engineer

Advantages during the pre-production phase are root cause analysis - only recently we've actually really started using the software to root cause the problems. We've found that looking at the contributor lists, for example, really help us get to the root cause of the problems and propose solutions. 

Laurence Allmark,

Senior New Product Quality Engineer, McLaren Automotive

The 3DCS technology brought our commitment to product quality and safety by design to an even higher level. The tool not only can quantify our technical decisions but truly helps our IPD teams to numerically and visually discuss spatial dimensional variations and its management early in the design phase.
