This paper deals with specific presentation of wokpiece volume and with functions for manipulating them in order to extract necessary data for various functions in virtual manufacturing environment. Basic idea was to use standard STL output of created model of blank material and convert to Z-map model. Functions for simulation of material removal process and extracting of geometry of instant tool immersion conditions are developed in Matlab environment. Extacing of engaging (tool immersion) map along discretized tool path is of great importance for aplication of model for instant cutting foces, based on simulation of discetized cutting geometry of the tool. Such simulation algorithm provides a solid base for prediction of cutting forces along tool path and for optimization of NC part program via feedrate sheduling. Presented methodology is tested in milling operations for machining of planar contours with flat end-mills, and some illustrative results are shown.
