What is Machine Capability Study?

Machine capability is a term from production engineering that identifies the stability and reproducibility of a production step on a machine in production.

It enables a statement to be made about the proportion of rework and scrap to be expected during operation of this machine.

One can quickly see from the key figures whether a machine or a process can produce with sufficient safety against errors.

In addition, automotive manufacturers require inspection and documentation of production to maintain consistent, high quality at all times.

Machine capability can be calculated during quality assurance using a CAQ system. Machine capability is closely related to the process capability indices Cp and CpK of a production process. In addition to control charting, machine and process capability metrics are an important element in monitoring and improving manufacturing processes.
