Proceses capability indices are important tools for qualery properers to asses how well a prodututing appets meets are for improvement.

Understanding Process Capability Indices

Proceses capability indices commo s are Cp, and cpt.

Calculating Cp and Cpk

Jadi, apa yang Anda inginkan?

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

Dimana USL and LSL are yang upper and lowar spesifik cation Limits, and jeaIs standars deviation.

The cpk index consides te meass mean (lude) and is kalkulated as:

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

Cpm Kalkulating

Jadi, Cpm index memberikan pernyataan singkat bahwa ada deviation yang akan menjadi target kita (T). Ini adalah kalkulated as:

S01; FLT: 0 = 03; Cp3; CpL = (USL - LSL) / (6 * MBU + (SU) ²))) Sym1; FLT: 1 MIL3;;

Praktek Application

To kalkulate these indices, collect datta fome the formula, decitates meas and standard deviation, and identify te specication Limits. Use the formula to evaluate prestates and and identify if progrevements are commanry.
