Working Diameter:

Formula to evaluate the correct working diameter

based on axial depth of cut (ap).

D2 where: D = Working Diameter w D D = Diameter of cutter insert centre to centre

w = Insert radius2 r a = Axial Depth of Cut p

where: f = Feed per tooth a = Radial Depth of Cut z e = Axial Depth of Cut

h = Average chip thickness a

m p r = Insert radius

Formula to find programmed feed rate based on radial engagement and

axial depth of cut. h m fz =

r 2 - r - a( )2 r 2 - r - a( )2

e p x r r

Formula to calculate the average chip thickness hm in relation with radial

engagement and depth of cut.

r 2 - r - a( )2 r 2 - r - a( )2

e p hm = fz x x r r
