80.0VR00-_R-16 Technical Information

Working Diameter:

Formula to evaluate the correct working diameter

based on axial depth of cut (ap).

D = D + 2 x r2 - (r -a )2

a w 2 p

p D 2 = Working Diameter where: D

w D = Diameter of cutter insert centre to centre D = Insert radius2 w r a = Axial Depth of Cut p

Formula to find programmed feed rate based on radial engagement and

axial depth of cut. h m f = z

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

engagement and depth of cut.
