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
defined
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: Line-by-line machining, retraction and stepover
at the edge of the surface being machined
4: Helical machining, smooth approach 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 transverse
approach 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
