Abstract:
1. A machine for machining large parts, comprising: a pair of spaced apart parallel first guides ( 3 ) extending in an X Cartesian coordinate direction; a mobile bridge ( 1 ) extending over the first guides in a Y Cartesian coordinate direction and mounted to the first guides for movement of mobile bridge in the X Cartesian coordinate direction; a pair of spaced apart parallel second guides ( 7 ) connected on the mobile bridge and extending in a Y Cartesian coordinate direction; a platform ( 5 ) mounted to the second guides on top of the bridge ( 1 ), for movement in the Y Cartesian coordinate direction; a parallel kinematics machine ( 8 ) comprising a plurality of interpolated axes ( 9 ) each with a lower end, and a head ( 11 ) connected to a lower end of the interpolated axes for movement of the head by the interpolated axes, the parallel kinematics machine being mounted to the platform for movement in a Z Cartesian coordinate direction; and an actuator ( 12 ) connected to the platform for moving the parallel kinematics machine in the Z Cartesian coordinate direction, so that the parallel kinematics machine is movable in all of the X, Y and Z orthogonal Cartesian coordinate directions.
