ELIMINATING DRILL OFFSET IN BUSH FIXTURES USING ROOT CAUSE ANALYSIS (RCA)

Drill offset in bush fixtures can significantly impact product quality and accuracy in high-precision manufacturing. Thisproject aimed to identify and eliminate the root causes of drill offset in bush fixtures using Root Cause Analysis (RCA).A systematic approach was employed to collect data, identify potential causes, and implement corrective actions. Theresults showed that machine calibration, fixture modification, process optimization, and material control were criticalfactors in eliminating drill offset. Additionally, the implementation of precision machining techniques and highprecision measurement tools ensured high accuracy and precision. The project demonstrated the effectiveness of RCAin identifying and eliminating drill offset, resulting in improved product quality, reduced scrap rates, and increasedproduction efficiency.
