Method for machining pipe based on laser cutting

Abstract

The invention relates to a method for machining a pipe based on laser cutting. The method comprises the following steps that (1) 3D pipe graphics are generated through a computer system; (2) cutting graphics are added or preset cutting graphics are guided, and desired machining coordinates are edited; (3) arris-crossing cutting technology parameter set is confirmed according to actual configuration of a laser cutting machine tool; (4) technology parameters of laser cutting are edited; (5) a machining surface of flat pipe is calibrated through the computer system; (6) score moderate compensation of all sides is conducted through the computer system; and (7) machining is started. By adopting the method for machining the pipe based on the laser cutting, training and using doorsill is lowered, requirements for diversity and visual editing are met in practical machining, the machining accuracy is improved by 70% or more than the industry average, machining sequencing of pipe pieces is supported, utilization rate of materials is optimized, and a wide application range is achieved.

Description

technical field [0001] The invention relates to the technical field of numerical control processing, in particular to the technical field of pipe cutting, and specifically refers to a method for processing pipes based on laser cutting. Background technique [0002] At present, the current pipe cutting processing modes in the field of laser cutting at home and abroad are as follows: figure 1 As shown, first draw the 3D graphics of the pipe in the CAD software, then import the special NC programming software and cover the cutting pattern, and then carry out the routine laser tool path calculation and then process it on the machine. This mode generally has the disadvantages of high threshold for use and training, the one-time generation of the laser tool path (pattern covering) cannot be edited, and the error of pipe size and fixture assembly cannot be effectively compensated, making the effect in practical application It is greatly reduced and cannot effectively meet the dive...
