Numerical control machine tool magazine control method based on EtherCAT bus

Abstract

The invention provides a numerical control machine tool magazine control method based on AN EtherCAT bus. The control system comprises an x-axis motor servo driver, a Y-axis motor servo driver, a Z-axis motor servo driver and a tool magazine motor driver, and further comprises the following steps that 1) a user sends a tool changing instruction through a PLC program of the numerical control system; 2) after the tool changing instruction is subjected to decoding processing, the instruction knife number is output and a tool changing macro program is called, a tool changing mark is set in the PLCprogram, and the position data to be moved by the tool magazine motor is output to a specified register after logical operation is carried out; and 3) an abnormal alarm program is activated when theuser tool changing instruction is abnormal, an alarm number set by the user is displayed on the system page, and alarm information is input; when the user tool changing instruction is not abnormal, the tool magazine is rotated to the instruction knife position, the tool changing and tool taking operation are executed by the numerical control machine tool, and the main program is returned after thetool changing process is ended. The method is convenient to use, simple in wiring and stable in operation.

Description

technical field [0001] The invention relates to a method for controlling a CNC machine tool magazine based on an EtherCAT bus. Background technique [0002] The control method of the traditional tool magazine is to write the corresponding control program through the digital input and output interaction between the tool magazine motor driver and the control system, so as to control the work of the machine tool magazine. This control method occupies a large number of system input and output addresses, and is connected through cables. The machine tool control program is relatively cumbersome and inconvenient to maintain. Because it occupies more IO addresses of the system itself, the cost increases. An 8-input and 8-output IO expansion Modules often cost hundreds of dollars. [0003] In addition, due to the use of too many cables, it is difficult to connect and organize, further increasing labor costs, and when one of the cables fails, it will lead to control disorder, and eve...
