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 working flowchart of the control method 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. The 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 method for realizing high-efficiency dry running in a numerical control system. The control method is based on the surface following function of the height sensor in the numerical control system, realizes the compression of non-processing time, and makes laser processing more efficient under the premise of ensuring equipment safety. efficient. The control method includes setting a predetermined retraction height H and a predetermined distance D before the end of the dry run, which can be completed by combining the three actions in the existing laser processing into one action, that is, the processing head directly runs in dry mode. The speed quickly moves to the next processing position. During this process, the processing head first retracts to the predetermined height H at the highest speed. Before reaching the next processing point (distance D from the next processing point), it starts to descend. , which reduces the non-processing time of the equipment and greatly improves the 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...
