Problems solved by technology

This method can effectively avoid the collision between the cutting head and the material due to the inconsistent surface height of the plate during dry running, but the non-processing time is relatively long, and the actual utilization rate of the equipment is not high

Embodiment Construction

[0021] refer to image 3 , the work flow diagram of the control mode for realizing high-efficiency dry running in the numerical control system of the present invention.

[0022] Taking CNC laser cutting in laser processing as an example, the embodiment of the present invention can be applied to a CNC laser cutting machine based on the automatic height tracking function, which automatically detects, calculates and synchronizes automatic retraction and head-down tracking when the CNC servo axis is running dry. automatic control method. This control method includes setting a retraction predetermined height H, and a predetermined distance D before the end of the dry run, including the following steps,

[0023] (1) Execution of a processing program is completed;

[0024] (2) Determine whether the actual distance d between the processing head and the next processing point is greater than the predetermined distance D, if yes, perform step (3), otherwise, perform step (4);

[0025]...

Abstract

The invention discloses a control mode for realizing high-efficiency dry running in a numerical control system, which is based on the surface following function of a height sensor in the numerical control system to realize non processing time compression and cause laser processing to be efficient on the premise of ensuring that equipment is safe. The control mode comprises setting a retraction height H and a preset distance D before dry running ends, thus three actions of the existing laser processing are combined into one action to finish, i.e. a processing head quickly moves to the next processing position directly at dry running speed; in the process, the processing head retracts to the preset height H at the maximum speed and begins falling when the processing head does not reach the next processing point (distance D away from the next processing point), thus reducing non processing time of the equipment and greatly improving the using efficiency of the equipment.

Description

technical field [0001] The invention provides a control method for realizing high-efficiency dry running in a numerical control system. Background technique [0002] Laser processing is the use of high-energy laser beams to cut, weld, mark, engrave, surface treatment, micro-processing and other processes on the surface of materials or parts. Usually, the laser processing system consists of at least four parts, namely laser, light guide system, laser processing head device and processing table. In the laser processing process, the height sensor, as an indispensable and important part of the laser processing head device, is one of the important auxiliary devices to ensure better processing quality. In modern laser processing technology, since the energy consumption of processing equipment and auxiliary materials is relatively large, how to control the ratio of the actual processing time to the total running time in the processing process, that is, when the above energy consum...
