Study and Realization of the Consistency of the Part Orientation in WEDM Process

In the comprehensive experiment, there was a problem that the punch and the push board could not be installed for the difference in orientation. Students can analyze and identify the causes by themselves. There were the punch symmetrical centerline deflecting holes connection, benchmarks inconsistencies and clamping error in the WEDM process. They proposed some countermeasures. Based on the measures, they smoothly completed the experimental teaching tasks. They eliminated the interference between mold parts during the assembly process. The parts moved freely and the wall thickness of injection molded parts was uniform.
