[0002] The grinding force of the existing CNC system grinding machine is generally detected by the force sensor installed on the machine tool, and then the detected value is transmitted to the grinding wheel motor driver to form a closed-loop control. The driver realizes the control of the grinding force by adjusting the speed. However, the existing CNC system Grinding machine because the grinding force is mainly related to the contact relationship between the grinding wheel and the workpiece, and the grinding force control is mainly to achieve the specified grinding result, but the existing machine tool can not achieve the specified grinding result only by adjusting the grinding wheel speed to control the grinding force In order to solve the above problems, it is necessary to provide a method that can control the grinding force of the grinder

Embodiment Construction
[0028] In the following description, numerous specific details are given in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these details. In other examples, some technical features known in the art are not described in order to avoid confusion with the present invention.
[0029] The application discloses a method capable of controlling the grinding force of a grinder.
[0030] The realization of the grinding force control method needs to use: a machine tool control device, several motor drivers, several machine tool axis motors and a grinding wheel radius measuring device.
[0031] The machine tool control device includes a control algorithm, a machine tool shaft movement algorithm and an actual grinding force calculation algorithm.
[0032] The motor driver is electrically connected with the machine tool control device.

The invention relates to a grinding force control method and a grinding machine based on it, belonging to B24B, the field of machine tools for grinding. The grinding force control method includes: S1. Inputting the set grinding force to the machine tool control device, S2. The machine tool control device obtains in real time the grinding wheel motor torque in the motor driver, the grinding wheel radius measured by the grinding wheel radius measuring device and the corresponding Actual grinding force, S3. The machine tool control device calculates the movement amount of the machine tool axis according to the set grinding force, grinding wheel motor torque, grinding wheel radius and actual grinding force, and sends it to the motor driver of any machine tool axis to control the movement of the motor. Make the grinding wheel of the grinding machine grind the workpiece at a predetermined position and speed, and realize the control of the grinding force. The invention solves the problem that the conventional machine tool cannot realize the specified grinding result only by controlling the grinding force by adjusting the rotation speed of the grinding wheel through the closed-loop control of the grinding force of the machine tool control device.
