For 670 cutter blades, for difficult-to-machine materials, the choice of different cutting methods has great differences in damage to the cutting fluid. No matter which cutting method is selected, the principle is the same, that is to reduce the cutting force and the temperature of the cutting zone as much as possible.
Using the cycloidal cutting method can minimize the cutting area, so that the actual cutting angle of the cutting fluid is minimized, thereby extending the heat dissipation time of each tooth of the tool and reducing the cutting temperature; using the spiral interpolation method can make the cutting amount per tooth relatively uniform ,To avoid the cutting force concentrated on a few teeth and accelerate the wear, this effect is most obvious especially in the corner; and the use of large feed cutting method, with a small depth of cut, a large feed to effectively reduce cutting Force, so that the minimum cutting heat is generated during processing, and the temperature in the processing area is the lowest.
