Thin-wall/thin-bottom milling method
The thin wall here refers to the small size in the direction parallel to the cutter axis and the large size perpendicular to the cutter axis (see Figure 6-21), while the thin bottom refers to the large size in the direction parallel to the cutter axis and the small size perpendicular to the cutter axis (see Figure 6-22).
The recommendation for thin-walled milling is to mill both sides of a thin-walled wall alternately at high speeds.
Figure 6-23 is an example of thin-walled milling. The area marked 1 is cut first, and the area of the opposite side of the label 2 has not been cut off at this time, and the cutting force that can resist the cutting of the cutter can be played: then the cutter moves to the opposite side, and the area of the cutting mark 2 is cut, and the cutting depth of this area is twice as large as that of the cutting mark 1, and the area of the opposite side of the mark 3 is not cut off at this time, and can resist the cutting force at the root of the cutting knife; Each of the back knives is supported by the opposite part of the material that has not been cut off in the lower part of the entire depth of cut.
