Cutting tool quality improvement: a case study of electronic parts manufacturer

Electronic parts are an important part in the modern manufacturing industry. The purpose of this study was to enhance the quality of cutting tools in electronic parts manufacturing process by utilizing statistical methods. Through these approaches, it was found that the cost of precision boring blade (S2F0409R05F35R10PTD) was significantly decrease from 457 THB to 315 THB, this research can maintain the process capability value (Cpk) at the customer satisfaction level (rather than 1.5) and reduce production cost from 2,104,739 THB per year to 1,598,857 THB per year (5 months payback period). The proposed statistical methods approaches could also be applied to other electronic parts manufacturing industries worldwide.
