Disclosed is a multi-axis workpiece manipulator or positioning device ( 10 ) having movement along two rectilinear axes (L 1 and L 2 ), two pivotable or tilt axes (T 1 and T 2 ) and two rotational axes (R 1 and R 2 ). The positioning device ( 10 ) includes a support base ( 12 ), a first member ( 18 ) attached to the support base ( 12 ) extending axially therefrom and a carriage ( 24 ) adjustably connected to the first member ( 18 ). The support base ( 12 ) is movable in a longitudinal path along a first rectilinear axis (L 1 ) and the carriage is movable along the first member ( 18 ) in a vertical path along a second rectilinear axis (L 2 ). A second member ( 30 ) is pivotably and rotatably attached to the carriage ( 24 ) and extends axially away from the carriage ( 24 ). The second member ( 30 ) can pivotably move along a first tilt axis (T 1 ) with respect to the carriage ( 24 ) and can rotate in a circular path along a first rotational axis (R 1 ). A third member ( 40 ) is pivotably and rotatably attached to an end of the second member ( 30 ), wherein the third member ( 40 ) can pivotably move along a second tilt axis (T 2 ) with respect to the second member ( 30 ) and can rotate in a circular path along a second rotational axis (R 2 ). A drive mechanism (D) operates the positioning device ( 10 ) for selectively positioning a workpiece (W) to be processed. This device ( 10 ) is particularly useful in fabricating compressor impellers.
