Enhancing Quality And Reducing Defects Through Statistical Process Control At Abc Manufacturing Limited

Abstract

Acquiring superior product quality together with reducing manufacturing defects stands as an essential requirement to boost operational performance and enhance customer satisfaction in modern manufacturing operations. Both higher rework expenses and scrapped products along with lowered brand quality result in decreased market capitalization for companies. Statistical Process Control (SPC) functions as a fundamental quality management solution through its data-oriented analysis which gives producers daily control over manufacturing parameters. ABC Manufacturing Limited which produces Y9T Calipers seeks to implement SPC for their key component production of Main Bore, Seal Groove and Lug Hole to achieve better product quality and defect reduction. This research uses process variable adjustments of spindle speed and cutting depth alongside feed rate to enhance process capability indices Cp and Cpk which leads to lowered manufacturing prices. Through the implementation of control charts together with Pareto analysis and regression models the specific parameters were tracked and optimized for better product consistency alongside cost-effective results. The outcome demonstrates that purposeful SPC interventions create high-quality results while decreasing defects and increasing process speed so manufacturing operations gain large financial advantages.
