Machines with extended kinematics
On machines with extended kinematics (both tool and workpiece are rotary), it is only
possible to turn each of the components with one axis.
The kinematic of the rotary tool is described with the first rotary axis (v
1
) and the two vectors
l
1
and l
2
, that of the rotary table with the second rotary axis (v
2
) and the two vectors l
3
and l
4
.
The two kinematic chain components for machines with rotary tool and rotary workpiece are
shown in the figure below.

Figure 2-45 Kinematic sequence with extended kinematics
The following kinematic type is defined for machines with a rotary tool and rotary workpiece:
$TC_CARR23 using letter M (extended kinematics)
Note
On machines with extended kinematics it is generally useful, as with machines where only
the table can be rotated, for the machine reference point and the reference point of the table
to be identical. The (open) chain component to describe the table (see figure) is then closed.
In this special case, the following formula applies: l
3
= - l

Rotary tool types T and M
For machine kinematics with a rotary tool (types T and M), the toolholder component with
orientation capability, which describes the tool or head component (as opposed to the table
component), acts, in conjunction with the active tool, as a new overall tool.
