Understanding Cp and Cpk

Cp presential potential capability of a process by comparing the widt the potential to the optive caparabioly limits.

Cp Kalkulating

Ini untuk for fp a:

S01; S01; FLT: 0 AF3; Cp = (USL - LSL) / (6 * WHI1; FLT: 1: 1; WAR3;

Dimana:

  • USL = Uppe Specification Limit
  • LSL = Lowir Specification Limit
  • = Proses standar deviation

Calculating Cpk

Te formula for Cpk os:

S01; FLT: 0 = 3; Cp3 = mir voicer; (USL - ASAL), (3 * VALP), (ASA- LSL) / (3 * GRA3; ASA1; FL1; FLT: 1 MIL33;;

Dimana:

  • Meaxos mean
  • USL = Uppe Specification Limit
  • LSL = Lowir Specification Limit
  • Diviation SURID SURARD

Application in Six Sigmana
