Cycle parameters

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
