5.4 Turning cycles
Menu item Meaning
Turning cycles rough and finish simple
contours in basic mode and complex
contours in expanded mode
Further information: "ICP contours", Page 416
Proportioning of cuts: The control calculates an
infeed that is <= Feed depth P . An
abrasive cut
is
avoided
Oversizes are considered in expanded mode
Tool-tip radius compensation is active
Safety clearance
after each cut:
Basic mode: 1 mm
Expanded mode: The safety clearance is set
separately for internal and external machining
Further information: "List of machine
parameters", Page 608
Cutting and infeed directions for turning cycles:
The control
determines the cutting and infeed directions from the cycle
parameters.
The decisive ones are:
Basic mode: The parameters for Starting point X , Z (in
Machine mode: current tool position) and Start point contour
X1
/
End point contour Z2
Expanded mode:
The parameters for Start point contour X1 ,
Z1
and
End point contour X2
,
Z2
ICP cycles:
The parameters for Starting point X , Z (in Machine
mode: current tool position) and starting point of ICP contour
