rpm = (1000 x m/min) / (3.14 x D ) 1 mm/min = (mm/rev) x rpm - maximum recommended depths shown - adjust speed and feed based upon resin type and/or fiber structure - 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 (available at www.sgstool.com)
