Usefulness of newest version of the JM-SPC computer program for a statistical analysis of production processes was examined. An analysis subject were results of measurements of 16 geometrical features of an Al-Si high-pressure die casting systematically controlled after machining on a coordinate-measuring machine. For analysis two criterion have been used: 1) Xave control chart and 2) a performance indicator of processes expressed by two commonly used indices: potential process capability index (Cp) and process capability index (Cpk).
