Promising methods of metal processing by cutting the surface of complex parts are considered. To ensure high productivity when processing complex surfaces on CNC machines, the tool is provided with additional high-speed complex-coordinated movements that ensure the displacement of the cutting edge relative to the cutting surface. The offset of the cutting edges relative to the cutting zone during milling reduces the temperature load on the teeth and, as a result, increases the tool’s durability. The faster the cutting edge leaves the cutting zone, the lower the heat load and the higher the wear resistance of the cutters. In this regard, it is important to increase the speed and accuracy of movements of the working bodies of the machine. To implement the required characteristics when performing technological operations, it is proposed to use an AC electric drive system based on a valve motor with vector control and an information and measurement system containing variable sensors, which has better technical, economic and mass-dimensional indicators compared to other types of electric motors. The results of computer simulation of dynamic processes of regulating the speed and torque of a valve engine that provide the required dynamic torque and acceleration are presented. It is shown that an AC electric drive based on a valve motor provides the implementation of the required speed modes.
