4.5 Recessing cycles
Cutting and infeed directions for recessing cycles
MANUALplus automatically determines the cutting
and infeed directions from the cycle parameters. The
decisive ones are:
„ Basic mode: The parameters for starting point X, Z
(Manual mode: current tool position) and contour
starting point X1 / contour end point Z2.
„ Expanded mode: The parameters for contour
starting point X1, Z1 and contour end point X2, Z2.
„ ICP cycles: The parameters for starting point X, Z
(Manual mode: current tool position) and starting
point of the ICP contour.
Undercut position
MANUALplus determines the position of an undercut
from the cycle parameters for starting point X, Z
(current tool position in Manual mode) and corner
point of contour X1, Z1.

Parting
Cycle for parting the workpiece
The recessing cycle group comprises
recessing, recess turning, undercut and
parting cycles. Simple contours are
machined in "basic mode," complex
contours in "expanded mode." With ICP
recessing cycles, you can machine any
type of contour defined with ICP (see
“ICP Contours” on page 242).
„ Proportioning of cuts: MANUALplus
calculates an infeed that is <= infeed
depth P.
„ Oversizes: In "expanded" mode.
„ Cutter radius compensation: Active
(exception: Undercut type K).
Undercuts can only be executed in
orthogonal, paraxial contour corners along
the longitudinal axis.
