济南激光切割加工时如何选择合适的穿刺点?

发表时间:2017-06-23 14:42  责任编辑:济南瑞福不锈钢有限公司  点击:

  激光切割加工工件时,先就是找到合适的位置进行穿孔。如何选择合适的穿刺点呢,下面济南激光切割加工金沙彩票投注厂家就来介绍该怎么选择激光切割机的穿刺点:

  The first step is to find the right place to punch the workpiece during laser cutting. How to choose the appropriate puncture point, the following Ji'nan laser cutting processing manufacturers to introduce how to choose the laser cutting machine puncture point:

  In the process of processing, the material is irradiated by a continuous laser to form a dent at the center, and then a molten gas is removed by a working gas stream coaxial with the laser beam to form a hole. This hole is similar to the threading hole in line cutting, laser beam as the starting point for the hole processing of contour cutting, usually flying light path of the laser beam line direction and the processed parts cutting contour tangent direction. Therefore, the laser beam to this period of time to the part contour cutting at the beginning through the plate, the cutting speed has a great change in the vector direction, i.e. the direction of vector rotation of 90 degrees, a vertical tangent direction to the cutting contour to coincide with the tangent angle and cutting contour, i.e. contour tangent is 0 degrees. This would result in a rougher cut surface on the cutting surface of the machined material, mainly in a short period of time when the direction of the laser beam moving in it varies rapidly. Therefore, we should pay attention to this when cutting parts with laser cutting.

  In general, the design of the parts have no demands on the surface roughness of cutting fracture, can not do in the laser cutting programming manual processing, let the software automatically control the puncture point; however, when the design has high roughness requirements for the processing of parts to the cutting section, it should pay attention to this problem, usually in the series of laser cutting process of the laser beam of the starting position to do manual adjustment, namely artificial for puncture point control. It is necessary to move the puncture point produced by the laser program to the required reasonable position so as to meet the requirement of the surface accuracy of the machined part.
