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
