Cycle parameters
Q215 Machining operation (0/1/2)?: Define
machining operation:
0: Roughing and finishing
1: Only roughing
2: Only finishing
Side finishing and floor finishing are only machined
when the specific allowance (Q368, Q369) is deined
Q389 Machining strategy (0-4)?: 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
3: Machining line by line, retraction and stepover at
positioning feed rate at the edge of the surface to
be machined
4: Helical machining, uniform infeed from the
outside toward the inside
Q350 Milling direction?: Axis in the machining
plane that defines the machining direction:
1: Reference axis = machining direction
2: Minor axis = machining direction
Q218 First side length? (incremental): Length of
the surface to be machined in the reference axis
of the working plane, referenced 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
Q227 Starting point in 3rd axis? (absolute):
Coordinate of the workpiece surface used to
calculate the infeeds. Input range -99999.9999 to
99999.9999
