2.8 Tool carriers with orientation capability
The kinematic chains used to describe the machine with rotary tool (general case) are shown
in the figure below:
Figure 2-30
Vectors, which describe offsets in the rotary head, are positive in the direction from the tool tip
to the reference point of the toolholder.
The following kinematic type is defined for machines with a rotary tool:
$TC_CARR23 using letter T
Machine with rotary workpiece
On machines with rotary workpiece, the vector l
than zero, this is ignored.
The kinematic chain for machines with rotary workpiece is shown in the figure below.
