Prediction and Compensation of Machining-Induced Shape Deviations in Finish Milling

In this work a method is developed to predict and compensate the machining-induced deflection of the ball-end milling tool by calculating the engagement conditions between the workpiece and the milling tool for each single NC tool path point. Sub-models for calculating the deflection and wear of the milling tool are integrated into to method to spatially transform the position of each NC tool path point individually towards the negative direction of the local surface normal vector.
