This borderline case is monitored by the control that detects abrupt changes in the
machining point on the basis of angular approach motions between the tool and normal
surface vectors. The control inserts linear blocks at these positions so that the motion can be
executed.
These linear blocks are calculated on the basis of permissible angular ranges for the side
angle stored in the machine data. The system outputs an alarm if the limit values stored in
the machine data are violated.
Path curvature
Path curvature is not monitored. In such cases, it is also advisable to use only tools of a type
that do not violate the contour.
Insertion depth (ISD)
Insertion depth ISD is only evaluated when 3D tool radius compensation is active.
Program command
ISD (insertion depth) is used to program the tool insertion depth for
circumferential milling operations. This makes it possible to change the position of the
machining point on the outer surface of the tool.
Syntax
3D tool compensation circumference milling
CUT3DC
ISD=<value>
Significance
CUT3DC
Activate 3D tool offset for circumferential milling, e.g., for pocket milling with
oblique side walls.
ISD
The clearance (
<value>) between the milling tool tip (FS) and the milling tool
construction point (FH) are specified using the command
ISD.
