Problems solved by technology

[0002] The existing laser pipe cutting machine equipment uses capacitive sensing to obtain the profile of the pipe, but capacitive sensing is a contact detection and has poor anti-interference performance. For example, when the pipe material contains impurities or there is interference from mechanical and electrical structures, its sensitivity, measurement The accuracy is easily affected and unstable, which cannot make the cutting accuracy of the equipment stable and reliable, and cannot read the corresponding accuracy value in real time
In addition, due to the non-standard pipe material, the pipe material will be hollowed out after cutting, and the available effective values ​​are less, so it is difficult to obtain the pipe material profile
