Abstract:

By analyzing the geometrical relationship of oblique cutting, the relationship between the oblique cutting parameters and the milling force coefficients is formulized, and the mathematical expressions describing the relation- ship between the cutter parameters and the cutting chatter are theoretically deduced. Moreover, the effects of helix angle and normal rake angle on the milling stability in the same milling parameter conditions are investigated, and the three-dimension stability graphs of the axial cutting depth, the radial cutting depth and the spindle speed are plotted. It is found from the stability graphs that the milling stability improves with the increase of the helix angle and the normal rake angle.

Key words: oblique cutting, helix angle, normal rake angle, three-dimension stability
