3-Axis And 4-Axis Transformation - Siemens SINUMERIK 840DE sl Function Manual

Special cases of 5-Axis transformation
The following transformations are to be entered as special cases of the general 5-Axis
transformation:
● 3-axis and 4-axis transformation
There are 2 or 3 linear axes and a rotary axis.
● Swivelling linear axis
One of the rotary axis rotates the 3rd linear axis.
● Universal milling head
The two rotary axes are positioned at a projectable angle in relation to one another.
Knowledge of the general 5-axis transformation is a prerequisite for all of these transformations.

3-axis and 4-axis transformation

Function
The 3- and 4-Axis transformations are distinguished by the following characteristics:
Transformation
3-axis Transformation
4-Axis transformation
Both types of transformation belong to the orientation transformations. Orientation of the tool
must be programmed explicitly. The orientation of the tool is executed in a plane perpendicular
to the rotary axis.
