1. Improve the cutting ability of the cutting tool of the drawing aluminum plate.

刀具的材料、幾何參數對切削力、切削熱有重要的影響，正確選擇刀具，對減少零件加工變形*關重要。合理選擇拉絲鋁板手板加工刀具幾何參數。

The material and geometric parameters of the tool have an important influence on the cutting force and the cutting heat. The correct choice of the tool is very important to reduce the deformation of the parts. The geometric parameters of the cutting tool of the drawing aluminum sheet are reasonably selected.

1.前角：在保持刀刃強度的條件下，前角適當選擇大一些，一方面可以磨出鋒利的刃口，另外可以減少切削變形，使排屑順利，進而降低切削力和切削溫度。切忌使用負前角刀具。

1. front corner: under the condition of keeping the strength of blade edge, the front corner should be selected larger, and on the one hand, it can sharpen the sharp edge. It can also reduce the cutting deformation, make chip removal smoothly, and further reduce the cutting force and cutting temperature. Do not use the negative front angle tool.

 

 

 

2.拉絲鋁板手板加工后角：后角大小對后刀面磨損及加工表面質量有直接的影響。切削厚度是選擇后角的重要條件。

2. processing angle of drawing aluminum plate hand plate: the rear angle size has a direct effect on the wear of the knives and the quality of the machined surface. The cutting thickness is an important condition for the selection of the rear angle.

粗銑時，由于進給量大，切削負荷重，發熱量大，要求刀具散熱條件好，因此，后角應選擇小一些。精銑時，要求刃口鋒利，減輕后刀面與加工表面的摩擦，減小彈性變形，因此，后角應選擇大一些。

In the process of rough milling, because of the heavy feed, heavy cutting load and high calorific value, the heat dissipation of the tool is required. Therefore, the rear angle should be selected small. When milling, the sharp edge is required to reduce the friction between the blade surface and the machined surface, so as to reduce the elastic deformation. Therefore, the rear angle should be selected larger.

3.拉絲鋁板手板加工螺旋角：為使銑削平穩，降低銑削力，螺旋角應盡可能選擇大一些。

3. screw aluminum plate hand plate processing helix angle: in order to make milling smooth, reduce milling force, spiral angle should be as large as possible.

4.拉絲鋁板手板加工主偏角：適當減小主偏角可以改善散熱條件，使加工區的平均溫度下降。

The main deflection angle of 4. drawing aluminum plate hand plate processing: the proper reduction of the main deflection angle can improve the heat dissipation conditions and reduce the average temperature of the processing zone.
