Control method and control system for rotating shaft of numerical control machine tool

Abstract

The invention is applicable to the field of numerical control machining technologies and provides a control method and a control system for a rotating shaft of a numerical control machine tool. The control method comprises the steps that a machine tool numerical control system receives input rotating angle parameters through an operation panel, generates a machine tool control code carrying the rotating angle parameters and sends the machine tool control code to a decoding unit; under a decoding mode corresponding to a servo controller connected with the decoding unit, the decoding unit analyzes the machine tool control code into a rotating angle value, which can be recognized by the servo controller, and sends the rotating angle value to the servo controller; and the servo controller controls a motor to rotate according to the rotating angle value so as to drive the rotating shaft to rotate to a designated angle. According to the control method, the decoding unit has multiple decodingmodes, and all the decoding modes are in one-to-one correspondence with the types of all servo controllers; and since the decoding units can be matched with multiple types of servo controllers, gooduniversality is achieved.

Description

technical field [0001] The invention belongs to the technical field of numerical control machining, and in particular relates to a control method and a control system for a rotating shaft of a numerical control machine tool. Background technique [0002] CNC machine tool is a high-precision, high-efficiency automatic machine tool, which automatically processes the processed parts according to the pre-programmed processing program. At present, most CNC system manufacturers only open three-axis (usually X, Y, Z three orthogonal linear coordinate axes) processing functions to domestic CNC machine tools. If more axial processing functions need to be added, additional expansion is required. . [0003] In the extended processing function, "rotary axis" processing is more common, that is, to perform rotary processing around the X-axis or Y-axis. Among them, the rotary axis around the X-axis is called the fourth axis, and the rotary axis around the Y-axis is called the fifth axis. ...

AI Technical Summary

Problems solved by technology

[0004] However, the addition of the fourth-axis and fifth-axis processing functions requires the original CNC system manufacturer to open the corresponding authority and purchase matching drivers and motors. The reason is that drivers and motors between different CNC system manufacturers often cannot be shared. , poor versatility

For example, if you use the FAUNC CNC system of Japan, if you want to increase the function of the fourth axis or the fifth axis, you can only purchase the servo controller and motor produced by the FANUC company in Japan, and you cannot use the German Siemens (SIMENS) company. servo controller and motor
