Abstract:

In a mechanical parts manufacturing process, the abduction matter operations by cutting tools have a variable importance according to the nature of manufacturing part and to its raw elaboration method. On one hand, the characteristics of machining operations depend on some "studies office" choices during the part conception (shape, material …). On the other hand, they also depend on some "methods office" choices (machining gamut, machines choice, tools, cutting parameters, tooling and tool paths ...). For the "methods office", some maladjusted choices due to misreading of cutting forces could change the part quality. In this order, we have studied the dynamic cutting force coefficients (CDFC) determination method, by using a dynamometer, and the developed inertial compensation method. This consists in a conception of simplified phenomenological cutting force model in the case of turning under orthogonal machining conditions in the presence of vibrations.
