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).

Effect of applied pressure on the quality of squeeze cast parts made from AlSi9Mg alloy
The results of the study of an influence of pressure in the direct squeeze casting process on the physical and mechanical properties of an AlSi9Mg alloy are presented. The specimens were made by casting the tested AlSi9M...
Plastic properties of cold-deformed ironbased sintered materials
Cold plastic forming of sintered metal powders has limited practical application because of, among others, the deformation degree and initial porosity of preforms. Cold forming is combined with a very drastic drop of pla...
