CUT TYPE rpm = sfm x 3.82 / D1
ipm = (inch/flute) x no. of flutes x rpm
PROFILE LIGHT*
• maximum recommended depths shown
Rw = .5 x D1 Rw = .05 x D1 • adjust speed and feed based upon resin type and/or fiber structure
Ad = 1.5 x D1 Ad = L2 • reduce speed when overheating causes melting or damage to resin
• reduce feed if delamination or fraying occurs
* finish cuts typically require reduced feed and cutting depths
• rates shown are for use without coolant; rates may be increased with coolant use
• dust collection is vital when machining dry
• diamond coating will increase tool life in graphite and composite materials
• refer to the SGS Tool Wizard for more complete technical information
