• Use the lower end of the speed range for 40 Taper Machines & the higher end of the speed range for 50 Taper Machines. • Higher feed per tooth should be used to start for radial depths of cut less than 25% of the tool diameter. Lower feed per tooth should be used to start for radial depths of cut greater than 25% of the tool diameter. • The above recommendations are for axial lengths of cut not to exceed 1.5 times the tool diameter for profiling and 1 times the diameter for full slotting. • The above parameters are recommended starting points only. If the tool is working well, without vibrations or significant noise, increase SFM and/or Feed Per Tooth in 5-10% increments. • Optimum speeds & feeds will depend upon material, setup, machine conditions & tool deflection. Higher or lower parameters may be required to achieve optimum machining conditions. • For lighter radial depths of cut, make certain to increase the feed rate to compensate for Radial Chip Thinning Factor (RCTF). Consult a formula or app to calculate. • Climb milling is preferred to Conventional milling. TECHNICAL MACHINING POINTS:
