Functions for processing of wokpiece CAD model for prediction and optimization of milling process
Apstrakt
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. Exacting of engaging (tool immersion) map along discretized tool path is of great importance for application of model for instant cutting forces, 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 scheduling. Presented methodology is tested in milling operations for machining of planar contours with flat end-mills, and some illustrative results are shown.
