Algorithm for Adjusting the Machining Modes of Anisotropic Materials

This article discusses the problems of machining anisotropic materials associated with the choice of the direction of cut relative to the fibers of the material. The use of a processing mode that is invariant with respect to the direction of the fibers causes a decrease in surface quality and premature wear of the tool used. The use of an additional feedback channel, by which it is possible to determine the current direction of the fibers of the material, can allow to adjust the processing mode in real time. Studies of the dependence of the torque of the milling machine spindle on the direction of the fibers of the processed anisotropic material are carried out. Based on the described principle and research, a block diagram and an algorithm for the operation of the control system that implement the correction of the processing mode of the material are proposed.
