Abstract

In the manufacturing environment, quality improves reliability, increases productivity and customer satisfaction. Quality in manufacturing requires the practice of quality control. This internship report investigates the level of quality control in National Aerospace Laboratories, in Aircraft Prototype Manufacturing Facility. The study involves data collection of Base plate of Main landing gear on daily bases. The data was collected two times (morning and afternoon shifts) per day. This was done for 12 days. Some of the data was collected from department. The physical observations from the company were analyzed using statistical parameters. Here the Objective is to Find whether process is capable of meeting specification by constructing charts and finding Cp and Cpk values for different dimensions (key quality characteristics). Results depicted that Cp and Cpk values are less than 1.33. Finally Cause and Effect diagram is laid for understanding Causes and increasing the Cp and Cpk value to 1.33.
