The process of uniformization of different commutator-seat constructions

Abstract

As part of the joint work of the Institute of Manufacturing Science at University of Miskolc and the quality assurance group of Robert Bosch Power Tool Ltd. we examined commutator seats used in power tool motors. We used inner problem-solving methods to the company’s problem. This study introduces the application of modern quality assurance methods, such as Pareto-analysis, Cause and Effect Analysis, 5Why, furthermore the tests of the root cause discovered by these methods.
