Process Capability Studies [The following is based in part on the paper “Process Capability Studies” prepared by M. Suozzi, Member of the Technical Staff, Hughes Aircraft Company, Tucson, Arizona, 27NOV90] Introduction Process capability is an important … Process capability is the standard measure of conformance to specifications. Quantity Select; PDF Download $ 6.95. Process capability is the ratio of actual process Values of Cp below 1.00 indicate the process is not capable of meeting specifications. • Process capability indices measure the degree to which your process produces output that meets the customer's specification. The capability of a process is defined as the ratio of the distance from the process center to the nearest specification limit divided by a measure of the process variability. This case contains four practice problems to help develop student understanding of process capability. Process Capability by Sanjaya Kumar Saxena The capability of a process is a statistical indicator of how well it is functioning, or, in other words, how successful it is at running within its specified limits. It is divided into five progressive stages: 1) Process Delineation, 2) Metrology Characterization, 3) Capability Determination, 4) Optimization, and 5) Control. In the absence of any special or assignable causes of variation, a process … • In a later modules we will discuss capability … The variation in the process with respect to specifications is measure quantitatively using PCA. Process capability is a critical performance measure that demonstrates the ability of the process to produce products according to the specifications set by management based on customer needs and expectations [Montgomery, 1990]. Printed Black & White Copy $ 7.25. The Machine/Process Capability Study methodology, M/PCpS, presents the steps necessary to achieve process capability in sequential order.

Product Overview. • If these assumptions are not met, the resulting statistics may be highly unreliable. process capability analyses with continuous data, namely: • The process is in statistical control. Bothe (1997) has defined “process capability as the ability of a process to meet customer expectations”. Process capability analysis (PCA) and Six Sigma methodology occupy important places in ... important problem modeling and solution … Measures of Process Capability - Process Capability Indices: Cp, Cpl, Cpu, and Cpk are the four most common and timed tested measures of process capability. Cp is called the “Process Potential” - it simply relates the Process Capability (6σ ) to the Spec Range; it does not relate the location of the process with respect to the specs. • The distribution of the process considered is Normal. A capability index relates the engineering specification (determined by the customer) to the observed behaviour of the process. the process, while adequate to meet specifications, will require close control. ...

Determining process capability [Vincent, 2003].
