Fundamentals of cardan milling head

Note
The following description of the cardan milling head transformation has been formulated on the
assumption that the reader has already read and understood the general 5-axis transformation
described in Section "5-axis transformation (Page 145)". Please note that where no specific
statements relating to the cardan milling head are made in the following section, the statements
relating to general 5-axis transformation apply.
Applications
A cardan milling head is used for machining contours of sculptured parts at high feedrates. An
excellent degree of machining accuracy is achieved thanks to the rigidity of the head.

Configuring the nutator angle φ
The angle of the inclined axis can be configured in a machine data:
$MC_TRAFO5_NUTATOR_AX_ANGLE_1: for the first orientation transformation
$MC_TRAFO5_NUTATOR_AX_ANGLE_2: for the second orientation transformation
The angle must lie within the range of 0 degrees to +89 degrees.
