Matrix Blank Description as Part of Module for Machining Parameters Generation along the Tool Path for Peripheral Milling

Abstract

Peripheral pocket or contour milling using flat end milling tool can be performed using different tool paths. Engagement angle, radial and axial depth of cut are key machining parameters which influence cutting force value and directly depend of tool path itself. Knowledge of these parameters values along the tool path is necessary for simulation and monitoring of cutting force during machining process. For that purpose, module for machining parameters generation along tool path is developed and briefly explained here. Key machining parameters are generated based on workpiece – tool interaction during tool movement, which indicate that it is necessary to have information about size and shape of blank workpiece and to import that information in program in useful format. This paper present detail description of geometrical representation of blank which transforms blank from bitmap image to matrix record suitable for determination of its intersection with tool. Module for machining parameters generation along tool path presents necessary base for development of methodology for choosing the most adequate tool path for machining of given contour considering minimum cutting force and dynamic stability.
