Design method of material removal process for minimizing workpiece displacement at cutting point

In the machining of flexible workpieces, the workpiece displacements caused by cutting forces become larger, which may deteriorate machining accuracy and reduce tool life. In this paper, we propose a design method to minimize the workpiece displacements at cutting points. The calculation method directly designs the material removal sequence, feed direction and tool orientation taking the varying static stiffness of the workpiece and cutting force vectors into account. The method is verified with the process design for the milling of a titanium alloy cantilever.
