Predicting of milling forces in a virtual manufacturing system
Апстракт
Forces prediction along the tool path is one of the basic goal functions of the virtual machining system for CNC milling operations. In this paper, the discussion is limited to the contour milling in the plane z=const, using the flat end mills. Predictions are based on the simulation of the instant values of the milling force components during one tool revolution. Simulation uses discretized cutting geometry (discs) of end mill. This paper presents two approaches for reconstruction of tool/workpiece contact area. The first one implies the approximation of the workpiece volume using the z-map. The second presented approach calculates entry/exit angles at the 2D milling operations with the constant depth. Reconstruction of these angles is based on the analysis of previously formed radial stock and description of the tool path. Presented procedures for the predicting of milling forces have been implemented in the Matlab. Results of experimental verification of the proposed procedures are ...presented.
