Technical information Cutting data calculation
Cutting data calculation
a e
=
Width of cut mm/radial depth of cut
Example: Disc mill 335.19 Total No. of teeth (ZNP) = 12 Effective No. of teeth (ZEFP) = 6
=
Depth of cut mm/axial depth of cut
a p
DC
=
Cutter diameter
f
=
Feed per revolution
Explanation: 6 inserts on one side of the cutter and 6 overlapping inserts on the other side are used to get the full width (a p ) ,which means ZEFP = 6.
=
Feed per tooth
f z
ZEFP
=
Effective No. of teeth for calculation of feed speed or feed per rev (see below)
n
=
RPM
Q
=
Material removal rate
=
Cutting speed
V c
=
Feed speed
v f
=
Feed speed
v f
Side milling Relative engagement of the cutter diameter (a e /DC=%) 30% 20% 10% 5% Multiply the feed per tooth by the following factor 1.25
