5.5 Recessing cycles
Menu item Meaning
The recessing cycle group compris-
es recessing, recess turning, undercut
and parting cycles. Simple contours are
machined in basic mode, complex contours
in expanded mode.
ICP recessing cycles machine contours defined with ICP .
Further information:
"ICP contours", Page 416
Proportioning of cuts: The control calculates a
constant recessing width that is <= P
Oversizes are considered in
expanded mode
Tool-tip radius compensation is conducted
(exception:
Undercut type K )
Cutting and infeed directions for recessing 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
