中厚板切割方法中數控切割如何來避免工件變形？

        在板材切割中，數控切割是常見的方式之一，所以我們在了解板材切割的同時，必須了解切割方法，這樣我們才能充分了解板材切割。所以今天，會講解一些這方面的知識內容，這樣我們可以在這方面有更多的知識和理解，可以增加自己的知識。當我們進行數控切割時，有時切割零件會出現變形，因此有必要采取一些措施來控制和防止。那我們該怎么辦呢？下面的小系列要具體分析和闡述�？刂魄懈罴�變形的有效措施一般如下：

1、使用的氧氣純度應足夠，因為這關系到切口表面是否光滑。如果氧氣純度不夠，則會使切口變得粗糙，從而影響切口質量。

2、多件工件切割完成后，不要急于清理，使變形得到有效控制。

3、如果是薄鋼板，則可以進行局部冷卻，或根據切割部位的長度、寬度和厚度，在編程中預先添加冷收縮值進行補償。

4、切割噴嘴與鋼板表面的垂直度誤差應幾乎為零，即切割噴嘴與鋼板表面應垂直，否則切割部位會出現尺寸誤差。

5、容易發生變形的工件，應放在整個板材的中間，與工件之間的距離要足夠。

6、選擇合理的切割順序，正確選擇穿孔點的位置，以免切割件變形。文章來源：（http://www.bjmaidao.com）
In plate cutting, NC cutting is one of the common ways, so we must understand the cutting method while understanding the plate cutting, so that we can fully understand the plate cutting. So today, I will explain some knowledge in this area, so that we can have more knowledge and understanding in this area and increase our knowledge. When we conduct numerical control cutting, sometimes the cutting parts will be deformed, so it is necessary to take some measures to control and prevent. So what should we do? The following small series should be specifically analyzed and elaborated. The effective measures to control the deformation of cutting parts are generally as follows:
1. The purity of oxygen used should be sufficient, as it relates to the smoothness of the cut surface. If the oxygen purity is not enough, the incision will become rough, thus affecting the quality of the incision.
2. After cutting several workpieces, do not rush to clean them, so that the deformation can be effectively controlled.
3. If it is a thin steel plate, it can be cooled locally or compensated by adding a cold shrinkage value in advance in the programming according to the length, width and thickness of the cutting part.
4. The perpendicularity error between the cutting nozzle and the steel plate surface shall be almost zero, that is, the cutting nozzle and the steel plate surface shall be vertical, otherwise the cutting part will have dimensional error.
5. The workpiece prone to deformation shall be placed in the middle of the whole plate with sufficient distance from the workpiece.
6. Select a reasonable cutting sequence and correctly select the position of the perforation point to avoid deformation of the cutting part.
