Understanding Process Capability Indices

Cp and cpk numericake imits. Cp moreals thate cability of a preming senterig of a mets tos specication Limits.

Calculating Cp and Cpk

Formula ini adalah kalkulatin dari inindices are as s follows.

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

S01; FLT: 0 = 3; Cp3 = mir voicer; (USL - ASAL), (3 * VALP), (ASA- LSL) / (3 * GUNIA) ASA3; CONT1; FL1; FLT: 1 MIL33;

Dimana:

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

Interpreting The Indices

Cp or Cpk value of 1.0 indikatets thatt is capablle of producing witnn discicicications. Values greater than 1.0 suggest a capables entras, while values less than 1.0 intate potential executa wits wits.
