Pull-off Strength Test Optimization

MICRO

  • Improve pull-off strength test efficiency by enabling use of OEM wedge grips

  • Problem: The test part could not be securely held in standard OEM wedge grips, requiring an improvised fixture that increased setup time and variability

Dimensioned sketch for reverse engineering in SolidWorks.

Results

  • Enabled use of OEM wedge grips for the test setup

  • Added a pin-bar handle to improve handling and prevent loss during setup and teardown.

  • Improved repeatability and ease of setup, reduceing operator setup time by ~20%

How?

  • Reverse-engineered OEM wedge grip jaw faces using an optical comparator

  • Redesigned the jaw faces in SolidWorks to accommodate the test part’s geometry

  • Replaced the original jaw faces in the OEM wedge grips with the custom redesigned ones.
