Finishing cut longitud.—Expanded
Select Roughing cycles lon/trans
Select Cut longitud.
Select the Expanded soft key
Press the Finishing run soft key
The cycle finishes the contour area from Start point contour to
End point contour.
When the cycle is completed, the tool remains at the
cycle end position.
Cycle parameters:
X, Z: Start point
X1, Z1: Start point contour
X2, Z2: End point contour
DXX: Add. correction number (range: 1 to 16)
Further information:
G58: Contour-parallel oversize
A: Start angle (range: 0° <= A < 90°; default: 0°)
W: Final angle (range: 0° <= W < 90°; default: 0°)
R: Rounding
T: Tool number – turret pocket number
G14: Tool change point
Further information:
ID: ID no.
S: Cutting speed or Constant speed
F: Feed per revolution
B1, B2: -B cham./+B round. (B1 at contour start and B2 at
contour end)
B > 0: Radius of rounding
B < 0: Width of chamfer
G47: Safety clearance
Further information:
MT: M after T: M function that is executed after the tool call T
MFS: M at beginning: M function that is executed at the
beginning of the machining step
MFE: M at end: M function that is executed at the end of the
machining step
WP: No. of spindle – Displays which workpiece spindle is used
to execute the cycle (machine-dependent)
Main drive
