Kinematic interaction and machine design
Representation of the kinematic chain
The concept of the kinematic chain is used to describe the kinematic interaction between a
reference point and the tool tip.
The chain specifies all the data required for the toolholder data block in a schematic. To
describe the concrete case with a particular kinematic, the relevant components of the chain
must be assigned real vectors, lengths and angles. The chain represents the maximum
constellation. In simpler applications, individual components can be zero (e.g. kinematics with
one or no rotary axis).
The machine does not have to have axes that rotate the tool and/or workpiece table. The
function can be used even if the orientations are set manually by handwheels or reconfiguration.
The machine design is described by the following parameters:
● Two rotary axes (v
for clockwise rotation facing the direction of the rotation vector.
● Up to four offset vectors (l
to machine or tool reference points).
