Cycle parameters
Q389 Machining strategy (0/1/2)?: Determine how
the TNC should machine the surface:
0: Meander machining, stepover at the positioning
feed rate outside the surface being machined
1: Meander machining, stepover at the feed rate for
milling at the edge of the surface being machined
2: Line-by-line machining, retraction and stepover at
the positioning feed rate
Q225 Starting point in 1st axis? (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
Q226 Starting point in 2nd axis? (absolute):
Starting point coordinate of the surface to be
machined in the secondary axis of the working
plane. Input range -99999.9999 to 99999.9999
Q227 Starting point in 3rd axis? (absolute):
Coordinate of the workpiece surface used to
calculate the infeeds. Input range -99999.9999 to
99999.9999
Q386 End point in 3rd axis? (absolute): Coordinate
in the spindle axis on which the surface is to be
face-milled. Input range -99999.9999 to 99999.9999
Q218 First side length? (incremental): Length of
the surface to be machined in the major 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
Q219 Second side length? (incremental): 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
STARTNG PNT 2ND AXIS. Input range -99999.9999
to 99999.9999
Q202 Maximum plunging depth? (incremental):
Maximum infeed per cut. The TNC calculates the
actual plunging depth from the difference between
the end point and starting point of the tool axis
(taking the finishing allowance into account), so that
uniform plunging depths are used each time. Input
range 0 to 99999.9999
Q369 Finishing allowance for floor? (incremental):
Distance used for the last infeed. Input range 0 to
99999.9999
