First, the surface slot. First choose the boundary, and then select the face.
1. The principle of determining the cutting zone of the tool is: In the selection of the boundary, the cutting surface of the tool in the boundary of the boundary is selected as the terminal surface, and the tool can drop from the high point to the low point. control. The choice of noodles are the entire surface, and the boundary can only be a area to be processed. There is no surface extension distance less than half of the diameter interval between the tool. Because the other side has enough waste, it can be automatically protected; pull the control low line because the low line is done because the low line is done because the low line is well. Control the low line without R gong.
2. Selection of tools: If the tool cannot spiral or oblique knife, or cannot be paid in the processing area, the area will be sealed and leaves secondary rough processing.
3. In front of the light knife, all the undained areas must be roughly treated. It is a small horn that contains two -dimensional horn, three -dimensional horn and closed area, otherwise the knife will be broken.
4. Second -level rough processing method: Generally adopt a three -dimensional slot method, a flat -bottomed knife, can be used to divide the plane slot and the appearance of the tool. Do not hurt other surfaces from the corner center to the selected boundary. Usually do not pull the border, depending on the situation, spirate it from a fast two -way angle, 1.5 degrees angle, 1 degree high, as a rod when digging the shape, not a spiral knife, adopt use The oblique line is given, usually an open filter, the cutting surface is spiral, the cutting surface is low, and the height of the cutting surface is not low. Small parts processing manufacturers
5. Back knife: Generally, there is no need for a relative back knife, using the back knife, and the opposite back knife.
Second, the plane grooves: milling various grooves, when the opening surface of the milling part, the edge requirements, in principle (greater than one diameter), the opening is greater than half of the diameter, and the outer edge is closed.
3. Appearance: Select the same layer of the plane and the appearance, improve the knife and the appearance layered (plane appearance), and the increase point and the knife point are a point. You do not need to improve the knife Z plane. It is usually correct correction (bybid).
