Research on Tool Position Solving Technology of Rolling Ball Method for Aero-Engine Blade Machining
For the five-axis machining process of aero-engine blades,a new tool position algorithm is proposed.By rolling a vari-able-radius ball cutter along the tool path and positioning the tool to cut the curved surface,a pseudo-radius is calculated for each grid point,and the most appropriate radius is selected as the rolling ball radius.This method avoids the typical traditional cycle detection interference and swings the tool until there is no overcut,which is easy to implement and easy to calculate.Finally,through simulation and cutting experiments,the feasibility and correctness of the proposed rolling ball method tool position solution method in the blade machining process are verified.
