A kind of fast arc cutting method

Abstract

The invention relates to the technical field of numerical control laser cutting machines, in particular to a quick circular arc cutting method. The quick circular arc cutting method comprises a step of conducting circular arc cutting through processing software of a laser cutting machine which is controlled by a computer, and is characterized by comprising the following steps: starting the processing software of the laser cutting machine, conducting laser cutting from a first circle; after laser cutting of the first circle; judging the positional relation between the next circle and the current circle and whether the circles are in the same direction; if yes, connecting an external common tangent and finding the next circle, or connecting an internal common tangent and finding the next circle; generating a novel cutting track, and cutting a second circle; after cutting of the second circle, judging whether the circle is the last one. Compared to the prior art, the circles to be cut can be connected along the tangent, the whole processing track is in smooth connection, and the machine tool cannot be greatly reduced in speed during the cutting process, so that the time can be greatly shortened.

Description

technical field [0001] The invention relates to the technical field of numerically controlled laser cutting machines, in particular to a method for rapid arc cutting. Background technique [0002] In the process of laser cutting, the positioning of different graphic cutting has always been a basic problem. Multi-circle cutting is one of the most commonly used examples, so the positioning of multi-circle cutting is particularly important in industry. [0003] Traditional cutting treats multiple circles as multiple graphics. After one graphics is processed, the cutting head needs to turn off the laser, lift it up, and then move to the top of the next graphics to be processed, then lower it, turn on the laser, and start Processing of the next graphic. If there are many graphics, the cutting head will rise and fall frequently. And due to the technical requirements of laser cutting, the cutting head can only be raised and lowered safely when the movement is stopped. Therefore,...

If there are many graphics, the cutting head will frequently rise and fall

And due to the technical requirements of laser cutting, the cutting head can only be raised and lowered safely when the movement is stopped. Therefore, after each graphic is processed, the machine tool needs to decelerate to 0, so that the cutting head can rise, and then accelerate to move to At the starting point of the next figure, the cutting head can only be lowered when the speed is reduced to 0. Repeatedly, it is very time-consuming and labor-intensive, and reduces the processing efficiency of the machine tool
