[Webinar] Causes For Dimensional Variation In Common Manufacturing Processes And How To Optimize Them With Tolerance Stackup Analysis

Recommended Posts

Dimensional variation is a defect characterized by the molded or fabricated part dimension varying from batch to batch or shot to shot with no apparent variation in the machine settings. Most of the variation in any given dimension on a manufactured part can be broken down into the following areas:
• Intimal departure from the nominal in the construction of the tool
• Variation as the tool ages and wears or undergoes maintenance
• Part to part variation due to the change in stroke length or mold closing
• Variation caused by the moving parts within the tool
• Variation in the raw material
• Variation in the process variables – velocity, pressure and temperature
• Measurement repeatability and reproducibility

Even if all of the above are minimized, there will still be part to part variation.

As product complexity continues to grow, assessing the effects of part tolerances and their impact on assembly becomes increasingly important to ensure product quality and performance. Tolerance stackup analysis (TSA) is essential to make sure assembly problems related to these variations are reduced or completely eliminated before the parts go into production. Checking and calculating the right tolerance is a painstaking task. More than 60% designers use spreadsheet for performing TSA. However, this method lacks flexibility, visual representation of CAD assembly and it is very tedious and error-prone process.

Geometric Stackup provides a simple solution for tolerance Stackup analysis on complex assemblies with unprecedented ease, speed and accuracy – reducing tolerance stack up calculation time from hours to minutes.

Attend the webinar to learn:
• Sources of variation for common manufacturing processes
• Compare the dimensional variation sources and its impacts for common mass production processes such as die-casting, forging and machining with plastic injection molding
• A simplified approach to Tolerance Stackup Analysis
• How to reduce stackup calculation time from hours to minute
