Abstract
Inspired by the commercial application of the Exechon machine, this
paper proposed a novel parallel kinematic machine (PKM) named Exe-Variant. By
exchanging the sequence of kinematic pairs in each limb of the Exechon machine,
the Exe-Variant PKM claims an arrangement of 2UPR/1SPR topology and
consists of two identical UPR limbs and one SPR limb. The inverse kinematics of
the 2UPR/1SPR parallel mechanism was firstly analyzed based on which a
conceptual design of the Exe-Variant was carried out. Then an algorithm of
reachable workspace searching for the Exe-Variant and the Exchon was proposed.
Finally, the workspaces of two example systems of the Exechon and the
Exe-Variant with approximate dimensions were numerically simulated and
compared. The comparison shows that the Exe-Variant possesses a competitive
workspace with the Exechon machine, indicating it can be used as a promising
reconfigurable module in a hybrid 5-DOF machine tool system.
