Calculating the Chip Load (s z ) s Z =Chip load per tooth z=Number of teeth in tool n=Spindle Speed in Revolutions per minute (RPM) v f =Feed rate English: Enter in feet per minute Metric: Enter in meters per minute z c =Number of teeth to make a complete kerf cut English: Chip load result is in thousandths of an inch (in.) s Z =(v f x 12) ÷ (z x n)x z c Metric: Chip load result is in millimeters (mm) s Z =(v f x 1000) ÷ (z x n)x z c 4 Confidential Information-Do Not Duplicate10-8-2010

5
Calculating the Pitch (p) p =Pitch or distance from tooth-to-tooth =3.14 D=Diameter of the tool English: Enter diameter in inches Metric: Enter diameter in mm z =Number of teeth in the tool English: Pitch result is in thousandths of an inch (.000) p=( x D) ÷ z Metric: Pitch result is in millimeters (mm) p=( x D) ÷ z 5 Confidential Information-Do Not Duplicate10-8-2010

Calculating the Rim Speed (v c ) v c =Rim speed (Cutting speed) D=Diameter of the tool n=Spindle Speed in Revolutions per minute (RPM) =3.14 English: Rim speed measured in feet per second (ft./sec.) v c =(D x x n) ÷ (12x 60)or (.262 x D x n) ÷ 60 English: Rim speed measured in feet per minute (ft./min.) v c =(D x x n) ÷ 12or.262 x D x n Metric: Rim speed measured in meters per second (m/s) v c =(D x x n) ÷ (1000 x 60) Metric: Rim speed measured in meters minute (m/min.) v c =(D x x n) ÷ 1000 10-8-2010 8 Confidential Information-Do Not Duplicate
