Bi-axial synchronous laser cutting machine control system

Abstract

The invention relates to a bi-axial synchronous laser cutting machine control system. The bi-axial synchronous laser cutting machine control system comprises a movement controller, a plurality of servo drivers and a plurality of motors. The bi-axial synchronous laser cutting machine control system is characterized in that the movement controller is connected with the servo drivers and the motors through a bus; the movement controller is also connected with a pulse width modulation (PWM) module through a communication module, and the PWM module is used for controlling the power and frequency of a laser device; the movement controller comprises a file reading unit, a parameter acquisition unit and a cutting control unit; the file reading unit is used for reading a cutting program file; the parameter acquisition unit is used for acquiring cutting parameters; and the cutting control unit is used for forming a control command according to the cutting program file and the cutting parameters and controls the laser device driven by the servo drives and the motors to achieve cutting of complex shapes according to the control command. By the adoption of the bi-axial synchronous laser cutting machine control system, higher-precision and higher-speed movement can be achieved.

Description

technical field [0001] The invention relates to the technical field of laser cutting, in particular to a dual-axis synchronous laser cutting machine control system. Background technique [0002] A laser cutting machine is an automatic equipment that irradiates the laser beam to the surface of the workpiece through the optical fiber, and with the help of oxygen (or nitrogen), the workpiece is quickly melted and evaporated to achieve the purpose of cutting and engraving. It has high precision, fast cutting, Features such as smooth incision, coupled with not limited to cutting pattern restrictions, automatic typesetting saves materials, and low processing costs, will gradually improve or replace traditional metal cutting process equipment. [0003] The two-axis synchronous laser cutting machine control system is currently mainly composed of a controller, a motor and a driver to realize cutting through the CNC function. The controller receives the command from the host computer,...

Problems solved by technology

From the above content, it can be seen that it still uses pulse signal control. Since the speed of the motor is determined by the transmission of pulses, it cannot guarantee high precision and high speed at the same time.
