CNC machine tool multi-axis control system and control method

Abstract

The invention discloses a numerical control machine tool multi-axis control system, which comprises a numerical control machine tool multi-axis control device and a numerical control machine tool. Thenumerical control machine tool multi-axis control device comprises a host, a motor controller, a hand wheel controller and a hand wheel hand-held end. The input end of the motor controller is connected with the first output end of the host through a serial communication interface; the input end of the hand wheel controller is connected with the second output end of the host through a USB interface; the first output end of the hand wheel controller is connected with the first output end of the motor controller through an IO interface; the hand wheel hand-held end is in wireless communication connection with the second output end of the hand wheel controller; the output end of the numerical control machine tool is connected with the input end of the host; and the second output end of the motor controller is connected with multiple spindles in the numerical control machine tool. The motor controller receives data information in different working modes; and the motor controller sends a control instruction according to the data information to control the multiple spindles of the numerical control machine tool. The invention also provides a numerical control machine tool multi-axis control method based on the numerical control machine tool multi-axis control system.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a multi-axis control system and control method of numerical control machine tools. Background technique [0002] With the wide application of CNC machine tools, the demand for multi-axis expansion functions on CNC machine tools has also increased. However, due to the different manufacturers of CNC machine tools, different CNC machine tools need to be equipped with motors corresponding to the manufacturer, which limits the number. Axis versatility. Furthermore, in the prior art, the motors of CNC machine tools from other different manufacturers need to be controlled by adding a separate external control PLC system to control other axes. CNC CNC machine tools send switch signals through M codes. , in accordance with the parameters set by the PLC itself to drive other axes to rotate, it cannot directly communicate with the CNC machine tool to receive any dat...

[0002] With the wide application of CNC machine tools, the demand for multi-axis expansion functions on CNC machine tools has also increased. However, due to the different manufacturers of CNC machine tools, different CNC machine tools need to be equipped with motors corresponding to the manufacturer, which limits the number. Shaft versatility

Furthermore, in the prior art, the motors of CNC machine tools from other different manufacturers need to be controlled by adding a separate external control PLC system to control other axes. CNC CNC machine tools send switch signals through M codes. , in accordance with the parameters set by the PLC itself to drive other axes to rotate, it cannot directly communicate with the CNC machine tool to receive any data transmitted by the machine tool, resulting in inconvenient use of on-site machine adjustment and certain safety hazards; and it is not controlled online through the CNC system of the machine tool , which makes the control system more complicated; and it cannot be used for a variety of CNC machine tools, and the price is expensive
