7. Adaptive Clearing avoids full width cuts when machining by generating a toolpath that progressively shaves material from the stock model in trochoidal motions The unique feature is that the cutting conditions are constant but the radius is always as large as possible so the result is a more constant feed rate and less tool vibration With a traditional roughing algorithm there is always a mixture le CIMCO Integration Pack User Guide 7 Mastercam HSM Performance of side and slot milling throughout the operation But since Adaptive Clearing guarantees that there will never be any full width slot milling you can use the recommended side milling cutting conditions from your tool manufacturer s catalogue Since the toolpaths from adaptive are always flat areas with constant load the feed and speed can be increased to 150 200 of the recommended values Further as the toolpaths are using side cutting conditions the stepdown for major steps is usually at least equal to the tool diameter so the wear on the tool is along most of the flute instead of only the corner of the tool prolonging tool life The tool plunges outside the stock and machines the part from outside in whenever possible only making ramp helix entry moves when entering cavities or when the tool boundary prevents plunging outside the part Contour machining This operation creates machining passes with constant Z height which run along con
