Pipe continuous cutting method

Abstract

The invention relates to the field of numerical control laser cutting, in particular to a pipe continuous cutting method. The pipe continuous cutting method involves a laser cutting machine and is characterized by comprising the first step that processing software of the laser cutting machine is started, and cutting parameters are set; the second step that the size of a pattern to be machined is read; the third step that laser cutting is carried out; the fourth step that feeding judgment is executed; the fifth step that when feeding judgment is executed, if the length of a remaining pipe to be machined is larger than or equal to the breadth stroke needed by one-time machining of a machine tool, a feeding request is sent, and if not, the sixth step is executed; and the sixth step that feeding movements are executed or machining is ended. Compared with the prior art, the feeding frequency in the pipe continuous cutting process can be reduced substantially, the feeding efficiency is improved, and machining time is shortened; the feeding movements are executed by an interpolation shaft for cutting movements, and multiple feeding movements are combined into one-time feeding, so that the whole pipe continuous machining process is more efficient.

Description

technical field [0001] The invention relates to the field of numerically controlled laser cutting, in particular to a continuous cutting method for pipes. Background technique [0002] In the laser cutting process, the continuous cutting of pipes has always been a basic problem. The continuous cutting of pipes is a solution for automatic feeding during the processing of pipes whose length exceeds the working stroke of the cutting machine. The traditional continuous cutting is completed by using multiple feeding actions. Each time a graphic is processed, the feeding action is called once to ensure that the pipe to be cut is within the working stroke, and then the processing of the next graphic is started. If the size of the figure to be processed is small, the feeding action will be performed frequently; and because the feeding action and the interpolation action of the pipe axis direction during the cutting process are usually not performed on the same axis, the additional ...
