Embodiment Construction

[0021] see Figure 1-8 , the present invention controls the numerical control laser cutting machine, the servo amplifier and the servo motor through the numerical control system of the numerical control laser cutting machine, and the storage digital control program computer in the numerical control system performs the following operations:

[0022] (1) Emergency stop part: receive the emergency stop signal, activate the emergency stop state or non-emergency stop state of the numerical control system.

[0023] The machine tool has three direction axes of X, Y, and Z and a W rotation axis, that is, the four axes that the CNC laser cutting machine needs to be controlled by the CNC system. The control panel and the hand-held part of the CNC system are equipped with a parallel equivalent emergency stop switch. Press the emergency stop switch, the emergency stop relay will act, and the watchdog circuit on the four-axis axis card will not be triggered. At the same time, the emergency...

Abstract

A control method for numerally controlled laser cutting machine features that a numeral control system is used to control said laser cutting machine, servo amplifier and servo motor. The PLC program of a computer in the numeral control system can execute such operations as enabling the computerized numeral control, detecting servo state, changing parameters of numeral control program, setting up the switch signals of each axises for original points, setting up laser frequency, duty ratio and climbing time, choosing laser mode and other parameters, reading BCD codes of auxiliary codes, converting them to decima numerals, and setting up the function of each code.

Description

technical field [0001] The invention relates to an industrial process control method, in particular to a control method for a numerically controlled laser cutting machine. Background technique [0002] Compared with other cutting methods, laser cutting has the characteristics of high speed, high precision and high adaptability. It can replace some punching processing methods that require complex and large molds, and can greatly shorten the production cycle and reduce manufacturing costs. At present, laser cutting has been widely used in sheet metal processing in many industrial sectors such as electrical switches, household appliances, textile machinery, engineering machinery, metallurgical equipment, automobile manufacturing, grain machinery, and light industrial machinery. CNC laser cutting system is the main content in the field of industrial laser processing. It is a typical optical-mechanical-electrical integration product. It usually realizes the automatic control of C...
