Specify associated data block values
The following associated data block values are specified for the toolholder shown on a
machine with rotary toolholder:
Description
x component of offset vector l
y component of offset vector l
z component of offset vector l
x component of offset vector l
y component of offset vector l
z component of offset vector l
x component of rotary axis v
y component of rotary axis v
z component of rotary axis v
x component of rotary axis v
y component of rotary axis v
z component of rotary axis v
Angle of rotation α1 (in degrees)
Angle of rotation α2 (in degrees)
x component of offset vector l
y component of offset vector l
z component of offset vector l
Explanation
The toolholder kinematic chosen in the example is such that the two rotary axes form an
angle of 45 degrees, which means that the orientation cannot take just any value. In
concrete terms, this example does not permit the display of orientations with negative X
components.
x component of the tool base dimension:
y component of the tool base dimension:
z component of the tool base dimension:
