Method and device for eccentricity compensation, computer equipment and storage medium

Abstract

The invention relates to a method for eccentricity compensation. The method comprises the following steps: obtaining an eccentric amount between a pipe fitting center and a chuck rotary center in themachine tool coordinate system; converting coordinates in a pipe fitting coordinate system taking the pipe fitting center as an origin to a chuck coordinate system taking the chuck rotary center as anorigin according to the eccentric amount to obtain the converted coordinates; and carrying out corresponding eccentricity compensation according to the converted coordinates. Through the eccentricitycompensation for the eccentric amount between the chuck rotary center and the pipe fitting center, the machining accuracy is improved. In addition, the invention further discloses a device for eccentricity compensation, computer equipment and a storage medium.

Description

technical field [0001] The invention relates to the application field of numerical control, in particular to an eccentricity compensation method, device, computer equipment and storage medium. Background technique [0002] Laser pipe cutting machine is a precision CNC machine tool that can process standard pipe shapes such as rectangular pipes, round pipes, and oval pipes, as well as other special-shaped pipes. In order to ensure machining accuracy, under ideal conditions, it is necessary to ensure that the clamping center of the chuck coincides with the rotation center during its movement. However, in reality, there is often a certain deviation between the clamping center and the rotation center of the chuck. In actual machining, due to the existence of this deviation, there is a certain deviation between the theoretical programming position and the actual positioning position. After this deviation is mapped to the workpiece, a machining error is formed, resulting in low m...

However, in reality, there is often a certain deviation between the clamping center and the rotation center of the chuck.

In actual machining, due to the existence of this deviation, there is a certain deviation between the theoretical programming position and the actual positioning position. After this deviation is mapped to the workpiece, a machining error is formed, resulting in low machining accuracy.
