Control Machine Tool

Permanent Magnet Synchronous Torque Motor (PMSTM) has the main characteristics of low speed, high torque, high precision and excellent stability, which can be applied to implement the direct driving technology for CNC (Computer Numerical Control) machine tool. In this paper, the mathematical model of PMSTM is simply introduced, and the various control strategies are discussed in detail. According to the requirement of high performance for PMSTM driving servo system in CNC machine tool, the corresponding suitable control method is employed in the feed servo system. The proposed scheme is also promoted to apply in the spindle system, the tool holder and the turntable of machine tool.

Tuning Function

It is known for rendering more torque in operation at low speed and suitably attaining high performance dynamic control for the inverter. This paper describes the research of ASR strategy for the spindle inverter control in CNC machine tool. The principles of the vector control and formulas for the coordinate transformation are illustrated. The accuracy of the torque depends on the accuracy of the motor parameters used in the control. So the powerful parameter tuning function should be enabled for all kinds of spindle to run effectively. The response of ASR will be perfect if the switching frequencies is used which is usually constant and set by the user.

Dc Servomotor

This paper presents some simulation based upon a dynamic model of a feed-drive within the structure of a CNC machine tool. A DC servomotor was considered as actuation device for the feed drive. For a given set of parameters for the position controller, two fuzzy types of fuzzy controllers were tested by means of simulation. The first fuzzy controller was a proportional one, with one input and one output, while the second one was a two variables one, with two inputs and one outputp.
