Description of a rotation
A data block for describing a rotation comprises one vector v
1
/v
2
to describe the direction of
rotation of the rotary axis in its initial state and an angle α1/α2. The angle of rotation is
counted positively for clockwise rotation facing the direction of the rotation vector.
The two toolholder angles α1and α2 are determined using a frame, independent of the active
plane currently selected (G17 - G19).
The tool orientation in the initial state (both angles α1 and α2 are zero) is (as in the default
case):
• G17: Parallel to Z
• G18: Parallel to Y
• G19: Parallel to Z
Assigning data to the toolholder
Example of a machine with rotary toolholder
The following settings are obtained at the mill head shown for a machine with toolholder with
orientation capability of kinematic type T:
Component of the offset vector l
1
= (-200, 0, 0)
Component of the offset vector l
2
= (0, 0, 0)
Component of offset vector l
3
= (-100, 0, 0)
Component of rotary axis v
1
= (1, 0, 0)
Component of rotary axis v
2
= (-1, 0, 1)
Tool base dimension of tool
reference point
(0, 0, 250)
Note
The tool reference point for the tool base dimension is defined by the reference point at the
machine.
