3.6 Programming of the 3- to 5-axis transformation

Axis se‐
quence:
Bits 0 - 2
BC' / B'C
CA' / C'A
CB' / C'B
1) Orientation of the tool in the zero position: Bits 3 - 4
x: Transformation type can be set
-: Transformation type cannot be set
Active machining plane
The tool orientation at the zero position can be set not only in the Z direction. For this reason,
ensure that the active working plane is set so that the tool length compensation acts in the tool
orientation direction.
The active machining plane should always be the plane according to which the tool orientation
is set in position zero.
Other settings
The geometry information used by the cardan milling head transformation for calculation of the
axis values is set in the same way as that of the other 5-axis transformations.

Traverse of the cardan milling head in JOG mode

JOG
In JOG mode, the linear axes can be traversed normally. It is, however, difficult to set the
orientation correctly by traversing these axes.
3.6 Programming of the 3- to 5-axis transformation
Switch on
The 3- to 5-axis transformations, including the transformations with swiveled linear axis and
cardan milling head, are enabled with the TRAORI(<transformation-no.>) command.
The enable of the transformation sets the NC/PLC interface signal:
