To Improve Quality and Reduce Rejection Level through Quality Control

Abstract

Organization now a days need to improve their product/process/services continuously and progressively for that lean six sigma is the holistic approach that address multiple aspect of organization competitiveness it is only tool to achieve overall operational excellence.CNC Cutting involves various processes which include machine setting, blade speed, machine parameter, clamping, cooling, etc. It is very difficult to produce defect free cutting. Occurrence of the defect may involve single or multiple causes. These causes can be minimized through systematic procedure of applying various tools and technique .This paper represents analyses and investigation of cutting defects and identification of remedial measures carried out at specific industry. Diagnostic study carried out on overall process of cutting. Cutting products revealed that the contribution of the five prominent defects in cutting rejections were found and they are taper cutting, over size, under size, rough surface and burr. It was noticed that these defects were frequently occurring at different locations. Systematic analyses were carried out to understand the reasons for defects occurrence and suitable remedial measures were identified and implementation of process.
