Common properties of machine types 1, 2 and 3
● The three linear axes form a right-handed, Cartesian coordinate system.
● The rotary axes are orientated parallel to the linear axes
● The orientation of the rotary axes are vertical, on one another.
● The tool initial state is in the negative Z direction.
Other properties of machine types 1 and 2
● Rotary axis 1 is the 4th machine axis of the transformation
● Rotary axis 1 changes the orientation of rotary axis 2
● Rotary axis 2 is the 5th machine axis of the transformation
● Rotary axis 2 does not change the orientation of rotary axis 1
Other properties of machine type 3
● Rotary axis 1 is the 4th machine axis of the transformation
● Rotary axis 1 rotates the tool
● Rotary axis 2 is the 5th machine axis of the transformation
● Rotary axis 2 rotates the workpiece
Note
Transformations not in accordance with the conditions mentioned here are described in their

Configuration of a machine for 5-axis transformation

Maximum number of 5-axis transformations per channel
Currently, no more than four 5-axis transformations can be parameterized per channel
Transformation type
The transformation type that is dependent on the machine type is set in machine data:
