Witryna18 mar 2015 · ASHRAM, Just to make it in brief for you, Cp is the maesure of Process Variation, where as Cpk is the measure of both Variation and central tendency of the Process (Mean). As you know, the greater the value of Cpk, the better is the capability of the process to produce parts within Specification. While only Process variation … WitrynaIf and are estimated to be 98.94 μm and 1.03 μm, respectively, then Index The fact that the process is running off-center (about 1σ below its target) is reflected in the markedly different values for C p, C pk, C pm, and C pkm .

WitrynaThe process capability index calculation is a measure similar to the Cpk index that also takes into account variation between the process average and a target value. If the process average and the target are the same value, Cpm will be the same as Cpk. If the average drifts from the target value, Cpm will be less than Cpk. WitrynaCp – This two-sided capability index compares the distance between the specification limits to 6-sigma: 6 USL LSL C P (1) Cpk – The smaller of two one-sided indices: 3 min , LSL USL C PK (2) Cpm – A modified version of Cp measuring variation around the target or nominal value T rather than the estimated process mean: 2 2 1 T C C P PM Witryna71) If the C pk index exceeds 1.
