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.

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.
