Use of the JM- SPC software to statistical control of high pressure die casting production-variable valued data type
Journal Title: Archiwum Odlewnictwa - Year 2009, Vol 9, Issue 3
Abstract
Usefulness of the JM-SPC computer program for a statistical analysis of variable valued data proceeded from an Al-Si high-pressure die casting production processes was examined. An analysis subject were results of dimensional measurement of 16 casting dimensions systematically controlled on coordinate-measuring machine. For analysis two criterion have been used: 1) X-s control chart and the performance indicator of processes by using of two commonly used indices: potential process capability index (Cp) and process capability index (Cpk).
