Laser micro-hole machining cooperative control system and method based on industrial personal computer

Abstract

The invention relates to a laser micro-hole machining cooperative control system and method based on an industrial personal computer. The system comprises the industrial personal computer, a numericalcontrol system and a cooperative control unit. The method comprises the steps that the industrial personal computer acquires machining parameters from a technological database according to operationof a user, sends a control command to the numerical control system according to the machining parameters and sends configuration parameters to the cooperative control unit; a laser is controlled to bestarted and stopped, and state information fed back by the laser is received; the numerical control system controls movement of a machine tool spindle according to the control command and controls the cooperative control unit to be started and stopped; and the cooperative control unit receives the configuration parameters, the starting and stopping quantity sent by the numerical control system and position information fed back by an adjusting motor of a machining head and sends a control signal to the laser, and circular constant-overlapping-ratio spiral scanning machining control is achieved. According to the laser micro-hole machining cooperative control system and method based on the industrial personal computer, the cooperative control unit coordinates work of the machining head and the laser and can control the whole machining process in real time, the machining reliability and high efficiency are guaranteed, and meanwhile the precision of a machined workpiece is high.
