Operation Manual

156 Teach-in mode
4.3 Single cut cycles
Contour rounding (with return)
The tool approaches the workpiece, machines the rounding that is
dimensioned relative to the corner of the workpiece contour and
returns to the starting point at the end of cycle. Cutter radius
compensation is taken into account.
Type of machining for technology database access: Finishing
Cycle execution if "With return" is active
1 Calculate "starting point and end point of arc"
2 Move paraxially from the starting point to the "arc starting point"
3 Move in circular arc to end point of rounding at programmed feed
rate
4 Retract and return on paraxial path to starting point
Cycle parameters
X, Z Starting point
X1, Z1 Corner point of contour
R Radius of rounding
J Element position (default: 1)—the algebraic sign
determines the cutting direction (see help graphic)
G47 Safety clearance (if "With return" is active)
T Turret pocket number
G14 Tool change point (if "With return" is active)
ID Tool ID number
S Spindle speed/cutting speed
F Feed per revolution
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 Displays which workpiece spindle is used to process the
cycle (machine-dependent)
 Main drive
 Opposing spindle for rear-face machining
