Abstract A measurement control system ensures that measuring equipment and measurement processes are fit for their intended use and it’s important in achieving product quality objectives. Process capability analysis is an important element of any quality improvement initiative. However, estimating process capability

It can summarize a great deal of information simply, showing the capability of a process and the extent of improvement needed. Having survey in an industry named Automotive Axles Limited at Mysuru. It is observed that before maintenance of the part 3107 C 1251 the manufacturing of Clutch collar was not within tolerance. In this project the process capability analysis is made during maintenance to evaluate the performance of Clutch collar in an industry named Automotive Axles Limited at Mysuru. Process capability indices are tabulated after the data had been…show more content…
A process is barely capable if Cpk is 1 to 1.33; it indicates that process quality is satisfactory.

2.2. Process capability study steps
A process capability analysis is made of four things that is the actual process, performance information, action on the process, and action on the output. Using this information, it is possible to determine the proportion of output that will be acceptable. To conduct a process capability study, the following steps are needed. The general process capability study steps are:

1. Select Critical Parameter: Critical parameters need to be selected before the study begins. Critical parameters may be established from drawings, inspection instructions, work instructions, etc.

2. Collect Data: A data collection system needs to be established to assure that the appropriate data is collected. It is preferable to collect at least 40-50 data values for each critical parameter. If this is not possible, corrections can be made to adjust for the error that is introduced when less than 40 data values are
