(1) When processing materials with high plasticity or elasticity, in order to reduce the friction between the flank surfaces, take a large relief angle; when machining high-strength and high-hardness workpieces, in order to ensure the strength of the cutting edge, a small relief angle should be taken; The machining cutting force is small, in order to reduce friction and improve the quality of the machined surface, a larger clearance angle is preferable;
(2) When rough machining, the cutting force is large, in order to ensure the strength of the cutting edge, a smaller relief angle can be selected; the finishing cutting force is small, in order to reduce friction and improve the quality of the machined surface, a smaller relief angle can be selected;
(3) The relief angle of the high-speed steel tool can be 2~3 degrees larger than that of the tungsten steel tool;
(4) When the radial wear of the milling cutter will affect the machining accuracy, for example, after the circumferential teeth of the keyway milling cutter are worn, the diameter decreases, which directly affects the width of the keyway, and the clearance angle should be appropriately reduced (usually 8 degrees).
(5) The friction between the back of the cutter teeth of the milling cutter and the workpiece is in the direction of the re-cutting speed, and the cutting thickness is smaller than that of general turning, so the wear mainly occurs on the flank face, so appropriately increasing the clearance angle of the milling cutter can reduce the wear.
