The Application of Process Quality Control Tools in the Production Process
Based on the quality survey of the working procedure of interior hole grinding of the ceramic shaft bush parts, this paper analyzes and studies it by the quality control tools such as Pareto diagram and Cause and effect diagram, and finds out the main deficiency indicator. The main influencing factor is that the verticality of the interior hole is Ultra-poor in the Process quality deficiencies. A series of the testing data of this deficiency indicator has been analyzed in order to obtain the factors influencing the deficiency indicator. Finally, comparison is made between the quality status before and after implementing improvement measures and measures of adjusting processes are taken to greatly improve the effect and the product qualified rate, which can provide reference for enterprises to improve the quality in the production process.
