Abstract

Excessive noise generation often occurs during the face milling of certain thin-walled aluminum workpieces. Theoretically, such noise can be reduced by utilizing milling cutters which employ non-uniform insert pitch. This study reports on the results of a series of tests undertaken to determine the noise reduction potential of four different non-uniform pitch cutters used to machine the engine mounting face of an aluminum transmission housing. It is shown that the use of non-uniform insert pitch does not necessarily reduce overall noise generation. There is, however, often a reduction in `noisiness'. The difficulties of applying existing `quiet' cutter design principles to workpieces of complex geometry are also discussed
