Cycle parameters
U Machining strategy (0/1/2) Q389: Specify how the
TNC is to machine the surface:
0: Meander machining, stepover at positioning feed
rate outside the surface to be machined
1: Meander machining, stepover at feed rate for
milling within the surface to be machined
2: Line-by-line machining, retraction and stepover at
the positioning feed rate
U Starting point in 1st axis Q225 (absolute):
Starting point coordinate of the surface to be
machined in the reference axis of the working
plane. Input range -99999.9999 to 99999.9999
U Starting point in 2nd axis Q226 (absolute):
Starting point coordinate of the surface to be
multipass-milled in the minor axis of the working
plane. Input range -99999.9999 to 99999.9999
U Starting point in 3rd axis Q227 (absolute):
Coordinate of the workpiece surface used to calculate
the infeeds. Input range -99999.9999 to 99999.9999
U End point in 3rd axis Q386 (absolute): Coordinate
in the spindle axis to which the surface is to be face
milled. Input range -99999.9999 to 99999.9999
U First side length Q218 (incremental value): Length
of the surface to be machined in the reference axis of
the working plane. Use the algebraic sign to specify
the direction of the first milling path in reference to
the starting point in the 1st axis. Input range:
-99999.9999 to 99999.9999
U Second side length Q219 (incremental value):
Length of the surface to be machined in the minor
axis of the working plane. Use the algebraic sign to
specify the direction of the first stepover in
reference to the starting point in the 2nd axis.
Input range -99999.9999 to 99999.9999
