Web1. When we talking about the capability of a process , we usually use cpk to show how well the process is. For example , if a dimension is a key characteristic of a product , we have USL and LSL from the drawing. We … The process capability index, or process capability ratio, is a statistical measure of process capability: the ability of an engineering process to produce an output within specification limits. The concept of process capability only holds meaning for processes that are in a state of statistical control. This means it … See more A company produces axles with nominal diameter 20 mm on a lathe. As no axle can be made to exactly 20 mm, the designer specifies the maximum admissible deviations (called tolerances or specification limits). … See more If the upper and lower specification limits of the process are USL and LSL, the target process mean is T, the estimated mean of the process is See more The mapping from process capability indices, such as Cpk, to measures of process fallout is straightforward. Process fallout quantifies … See more • Process (engineering) • Process capability • Process performance index See more Process capability indices are constructed to express more desirable capability with increasingly higher values.
