Rw = D1 31 Rw = .05 x D1 • maximum recommended depths shown
Ad = D1 Rw = .5 x D1 Ad = L2 • adjust speed and feed based upon resin type and/or fiber structure
Ad = 1.5 x D1 • 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
