To Improve Manufacturing Process with the Help of Statistical Process Control (SPC)

The importance of quality has been long recognized in the business environment in order to obtain or manufacture higher quality products. In a manufacturing environment, quality improves Reliability, increases productivity and customer satisfaction. SPC study is a very important tool in production process in order to achieve the Process variation. It is also used to define process capability and stability. Process capability is shown by Cp. The Cp index is used to summarize a system's ability to meet two-sided specification limits (upper and lower). The higher the Cp value the smaller the spread of the system’s output. Cp is a measure of spread only. A process with a narrow spread (a high Cp) may not meet customer needs if it is not centered within the specifications. Cp and Cpk will be equal when the process is centered on its target value. If they are not equal, the smaller the difference between these indices, the more centered the process is.SPC study is performed in any of process in industries. In this, I will be study with the help of SPC, online Control Charts at workplace to find out the variation in the manufacturing process.
