Corner cutting control method in cutting processing system

Abstract

The invention relates to a corner cutting control method in a cutting processing system. In the method, the system firstly detects and determines the correspondence relationship between the cutting speed and the cutting power of a cutting material under the requirement of same cutting seam width according to the cutting material and the maximum permissible error value set by a user, and then determines the correspondence relationship between the cutting speed and the cutting power during current processing; and in the cutting process, the system detects the cutting speed in real time and obtains the corresponding cutting power according to the correspondence relationship between the cutting speed and the cutting power during current processing, and controls the output cutting power in real time. Therefore, by using the corner cutting control method, the output of the cutting power can be reduced when the cutting processing system is in a corner position requiring a lower cutting speed, so that the smoothness of the cut corner is guaranteed, and the phenomenon of color change due to overburning is effectively avoided. Besides, the application method provided by the invention is simple and convenient, and the application range is wider.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tool control, in particular to the technical field of cutting processing control technology of numerical control machine tools, and specifically refers to a corner cutting control method in a cutting processing system. Background technique [0002] In the current cutting process of CNC machine tools, the incision is generally required to be smooth and clean, and the cutting accuracy meets the requirements. Taking the laser cutting system as an example, when cutting certain expensive materials, the requirements for cutting accuracy and cutting quality are also higher. These processing materials require smooth cuts and no overburning and discoloration at the cutting boundaries. [0003] For the above process requirements, in the existing cutting processing system, the pulse laser control method usually used at the corner is used for processing. Although this method can partially so...

Problems solved by technology

[0003] For the above process requirements, in the existing cutting processing system, the pulse laser control method usually used at the corner is used to deal with it. Although this method can partially solve the problem of overburning at the corner, it affects the smoothness of the cutting part.

For cutting systems other than laser cutting systems, there is no effective way to meet the above cutting process requirements.
