4.1.3 Basic tool orientation example
Basic orientation in the bisector
A milling tool is defined with length
L1=10
whose basic orientation is in the bisector of the X-
Z plane.

Description of example:
In
N10
to
N60
, a milling tool is defined with length
L1=10
(
N20
). The basic orientation is in
the bisector of the XZ plane
N40
to
N60
.
In
N70
, the tool is activated and the zero position is approached. As a result of the tool length
the machine positions
X0 Y0 Z10
are thus obtained in this block.
In
N80
an incremental traversing motion is performed from 10 into tool direction. The
resulting axis positions are thus
X7.071 Y0 Z17.071
.
4.1.4 Calculation of compensation values on a location-specific and workpiece-specific
basis
Tool with adapter
A tool with adapter and toolholder with orientation capability is defined in the following
program example. In order to simplify the overview, only length
L1
is different to zero for the
additive and insert offsets and for the adapter in case of the tool itself. The offset vectors of
the toolholder with orientation capability are all zero.
