The relation between Statistical Process control (SPC) and Production is the need of today’s organization. Since any Production Industry has almost one of the most important objective that to minimize the cost associated with their product and services. This can be achieved by improving and developing new strategy among these departments. So, it is necessary to study the various parameters of the Statistical Process Control and Production Department. For this purpose, a commercial component Y9T caliper has been selected to understand the relations between the parameters related to Production process. In the Present approach, study has been done to analyze the component Parameters as per requirement of customer of ABC Manufacturing Pvt. Ltd. Total three trials have been taken on Lug Hole Center Distance of Y9T caliper. The SPC analysis and Investigations of Process Capability has been understood and Studied by self-Investigation for Process Capability Analysis by varying production parameters that Spindle Speed, Feed and Depth of Cut. The observations are taken based on sampling data taken by Process Sheet. The result shows that, there is very close agreement between the SPC parameters and Production parameters. This Prove that optimization of Process Capability index improves the process performance and Rate of productivity.
