Using the Statistical Tools in Machine´s Capability Evaluation – Part 2

Abstract

The pressing machine for operation injection was considered as incapable. Therefore it was necessary to apply correction actions to make the machine capable. We applied following correction actions: regular monitoring of machine´s capability, mainetance and repair actions, setting the machine to the middle of tolerance zone. After correction actions were calculated values of scrap index for finding if the pressing machine is capable to produce in demanded parameters. The scrap index was 0,728%, which is lower than four months before (in the period from November till March this index was 3,096%). So we can consider the machine as capable.
