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

刀具的材料、几何参数对切削力、切削热有重要的影响，正确选择刀具，对减少零件加工变形*关重要。合理选择拉丝铝板手板加工刀具几何参数。

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：在保持刀刃强度的条件下，前角适当选择大一些，一方面可以磨出锋利的刃口，另外可以减少切削变形，使排屑顺利，进而降低切削力和切削温度。切忌使用负前角刀具。

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.拉丝铝板手板加工后角：后角大小对后刀面磨损及加工表面质量有直接的影响。切削厚度是选择后角的重要条件。

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.

粗铣时，由于进给量大，切削负荷重，发热量大，要求刀具散热条件好，因此，后角应选择小一些。精铣时，要求刃口锋利，减轻后刀面与加工表面的摩擦，减小弹性变形，因此，后角应选择大一些。

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.拉丝铝板手板加工螺旋角：为使铣削平稳，降低铣削力，螺旋角应尽可能选择大一些。

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.拉丝铝板手板加工主偏角：适当减小主偏角可以改善散热条件，使加工区的平均温度下降。

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.
