1. First set through the node editing tool. When choosing spiral cutting, the cutting angle is the spiral angle, that is, the included angle between the spiral and the horizontal plane.

2, and then choose the profile cutting, cutting angle refers to the angle between the diagonal and the horizontal plane.

3, and then the angle of the knife is generally between 0.5 and 5 degrees. The harder the material, the smaller the angle. Just find the right angle to cut the knife.

4. Allowance setting: firstly, the machining allowance for rough machining of metal materials is 0.05~0. 10, and a larger value is selected when the tool length-diameter ratio is greater than 5.

5. Furthermore, the machining allowance for rough machining of nonmetallic materials is 0. 15~0.25, and when the length-diameter ratio of the tool is greater than 5, the larger value is taken.

6. Then, the machining allowance of semi-finishing of metal materials is 0.02~0.04, and when the length-diameter ratio of the tool is greater than 5, the larger value is taken.

7. Then engrave the surface with a surface engraving machine, and the parameter is the surface allowance of the surface.

8. Finally, plane carving, the parameter is the side margin of carving, which should be adjusted according to the specific situation when processing.
