Use of some quality tools for optimalisation of exchange grinding wheel process

The selected quality tools were used in the organization to optimize the process of exchange of the grinding wheel. Test study, conducted in the organization indicated that the wheel may be changed every 270 hours of continuous operation. The use of the calculated cycle in practice has increased the number of manufactured products in the case of non-conforming products. The problem has been solved by using quality tools and analysis of the obtained results. For this purpose, we conducted: brainstorming, Pareto-Lorenz analysis and implemented the Sheward’s Charts. The results of the research has helped to identify the causes of the differences arising between the testing process and the actual course of the grinding process and to determine the optimum operating times for each wheel positions.
