7 Phases to Robust Design:How GD&T, Feature Functionality, & Exact Constraints Define Robust Assemblies
Tim Bogard
Sigmetrix
Curriculum
Tim is the leading expert on the development and integration of tolerance and variation analysis technologies driving unique engineering solutions into the CAE/CAD/CAM market. Over the past 25 years, he has worked with engineering management in over 1000 global companies improving lean engineering processes toward more robust products.
Tim founded Sigmetrix in 1999 as a divesture from Raytheon/Texas Instruments, creating a dynamic and focused organization, specializing in the development of unique, integrated, engineering analysis tools to address the need of mechanical engineers, manufacturing engineers, and quality professionals to understand the impact that imperfect parts and assemblies have vs. the idealized world of CAD. He has led the growth and expansion of this high performance company, developing strategic relationships with key universities, PLM vendors and software integration experts creating a global enterprise capable of meeting the growing needs of manufacturing companies.
Prior to forming Sigmetrix, Tim was Director of Engineering at Texas Instruments and Raytheon, where he helped develop the Design for 6 Sigma strategies and design technology centers supporting multi-disciplined engineering processes for advanced development programs.
Abstract
Attendees will understand how to focus on the simplest, but complete mechanical assemblies and part definitions utilizing technologies available today. A demonstration of GD&T Advisor will also be included in the session.
An assembly is a system and as a result, the development of the assembly should be managed in a systemic manner. There are two thoughts on design – top down, and bottom up. Top down allows the system to be thought out as you evolve the design. However, with the lack of good assembly level tools, bottom up design occurs most of the time. Many engineers/designers create parts before they fully understand all the assembly functions. Many times the parts are created out of context which creates a need for a labor intensive checks and balances, which are dominated by the poor application of Geometric Dimensioning and Tolerancing.
Attendees will learn more about the good, the bad and the ugly of GD&T, what technologies are available and examples of what companies around the world are doing to address the.
With a new approach, the applying of GD&T can be comprehensively addressed across all major steps of a product life cycle.
