Tool with two-axis swivel head (machine type 1)
Workpiece with two-axis rotary table (machine type 2)
Tool and workpiece with single-axis rotary table and swivel head (machine type 3)
Rotary axis 1 is treated as the 4th machine axis of the transformation.
Motion of 1st rotary axis changes the orientation of the 2nd rotary axis.
Rotary axis 2 is treated as the 5th machine axis of the transformation.
Motion of 2nd rotary axis does not change the orientation of the 1st rotary axis.
1. Rotary axis (4th machine axis of transformation) turns the tool.
2. Rotary axis (5th machine axis of transformation) turns the tool.
in negative Z direction.
Machine types for 5-axis transformation
Note
Transformations that do not fulfill all the conditions mentioned here (3 and 4-axis
transformations, orientation transformation with swivelling linear axes, universal milling
head) are described in separate sub chapters.
