Improving dimensional analysis within PolyWorks® through GD&T

There are multiple ways to align and report dimensional analyses using metrology equipment. Now that GD&T has become more accepted, metrology software needs to adapt and apply the appropriate GD&T requirement to each measured feature. By focusing on the differences between datum reference frame alignments and traditional alignments, this presentation will reflect on the rising potential for PolyWorks’ market-leading GD&T tools to improve accuracy when reporting engineering dimensional requirements compared to a standard dimensional analysis. In addition, it will provide examples of dimensional analysis with PolyWorks 2016 that involve complicated GD&T callouts via custom solutions.

Biography

Based in Fremont, California, working at Tesla as a Sr. Dimensional Engineer, Mathieu Desjardins has 9 years of experience in: metrology, GD&T, reverse engineering, and tool design. Half of his career was spent in consulting services, which exposed him to industries all over the world. With 7 years’ experience in PolyWorks, his familiarity spans every module, from reverse engineering to probing, bringing expert knowledge of GD&T to accurately perform dimensional analyses. His current endeavor at Tesla has him working on a task force team as the expert in 3D metrology, tooling inspection, and GD&T analysis. Furthermore, he supports and trains the metrology team working with PolyWorks.

Understanding GD&T using PolyWorks® visualization tools

Geometric Dimensioning and Tolerancing, GD&T, is the engineering language many novice and experienced inspectors continue to struggle with. Compound primary datum features and datum shifts can be difficult to report and correct when not understood. AGCO’s inspection team has been using the powerful visual tools inside PolyWorks with its SMART GD&T to bring GD&T to life. Kevin will demonstrate how, with a few simple clicks and tricks and adherence to the standard, many of the advanced concepts of GD&T can become easy to view and understand. When Maximum Merial Boundaries and Related Actual Mating Envelopes become part of the standard inspection report, AGCO’s increased the level of communication and enabled smoother product introductions with fewer revisions.

Implementing design changes into production tooling

In the automotive industry, safety, quality, and technology are ever-changing in vehicle and process design. To remain competitive, engineering changes are being made to the current production models on a continuous basis; changes can be minor, such as modifying a fillet radius or altering the current panel shape. Taking engineering changes from the digital world and applying them to production tooling can be a challenge. Often, the CAD data for the tool, if available, is not up to date to the current condition of the tool. Many times, engineering change information may come in the format of part CAD data instead of tool CAD data. This part CAD data normally does not reflect the current tooling condition because of allowances for over bending, clearances, or interferences in the tooling. In these cases, incorporating the engineering change into a current scan of the tooling is the best solution. This is where PolyWorks|Modeler™’s CAD reconstruct and morphing tools become an essential part of the process.

Biography

Kenny Gowen is the scanning and machining lead for the stamping shop at Toyota Motor Manufacturing Indiana. He works within the Die Maintenance department and has been with TMMI since the start of production at that facility in 1998. He has worked in the Tool and Die field for over 27 years building and maintaining production stamping dies. For the last 10 years at TMMI, Kenny has developed the use and implementation of 3D scanning technology for stamping die repair. His work is being implemented at other Toyota manufacturing plants across the US. At Toyota, Kenny has been granted a U.S. patent and a licensed Toyota trade secret for his work. He is actively involved in applying PolyWorks functions in the repair of stamping tools.
