Pulley executing subroutine (Subroutine 50)
The tool data is:
D=12
F=2
NOSEA=90
NOSEW=4
CUTA=0
Calibrated for the corner indicated by the arrow.
The Call parameters of the subroutine are:
P100 = Angle between the sides of the pulley.
P101 = Absolute Z center coordinate of the pulley.
P102 = Outside diameter of the pulley.
P103 = Depth of the groove (in radius).
P104 = Width of the groove.
P105 = Safety distance.
P106 = Maximum machining depth.
P107 = Finishing stock.
P108 = Cutting feedrate.
P109 = Roughing feedrate in mm/rev.
P110 = Finishing feedrate mm/rev.
The necessary points for the roughing operation are:
