The key reason of processing technology, from the perspective of our careful hardware technology, there were many reasons that would have a positive impact on the surface roughness of its parts. The key point is that the tool still has the material of the workpiece, and it is formed due to the condition of numerical control. As for the geometric reason, if it is mainly affected by the tool form, the deflection angle of the deflection angle pair and so on will have a greater impact on the surface roughness.
When we reprocess plastic raw materials, we will also form strip cutting to form accumulated cutting tumor, and the hardness is still very high. In the process of workpiece cutting, the blade fillet and extrusion can deform the metal raw materials, which will cause the surface to become rough and critical, and the surface function of accumulated cutting tumor will be completely irregular, so it is very simple to make the workpiece surface appear different knife marks in depth, width and width. For example, the rotation speed does not match the cutting speed, the raw material is too hard and the cutter is too much, the workpiece is not compressed, the workpiece elasticity is too large, the rubber finished products such as the cutter body is too long, the cutter bar vibrates during processing, the machine tool itself such as: the movement gap of lead screw line rail is too large, etc. All of these will inevitably increase the roughness of the part surface.
