Data Analysis in an Investment Casting Foundry for Process Improvement

This paper describes the need of a data acquisition system in the manufacturing facility and use of data analytics tool in manufacturing facility (Investment casting foundry), a penalty matrix approach is used to find the reasons. Manufacturing Processes have many process inputs. Statistical process control (SPC) techniques help discover special cause variation. The data analysis technique presented in the paper helps in reducing the rejection, to find the optimal parameter ranges with common cause variation.
