Abstract:
A machine for carrying a working head and having movement in three orthogonal axes with parallel kinematic movement comprising:a) a fixed structure; b) a flat mobile structure; c) a passive structure which has at least one jointed frame, said jointed frame affixed at one end to said fixed structure by a first union and at the other end to said flat mobile structure by a second union, one of said first or second unions being articulating; d) a spatial mobile structure movably affixed to said flat mobile structure so as to move linearly with respect to said flat mobile structure, said spatial mobile structure for carrying the working head; e) three movable arms, each of said arms affixed at one end to said fixed structure by a third union and at the other end to said spatial mobile structure by a fourth union, wherein one of said third or fourth unions has two degrees of freedom and the other of said third or fourth unions has three degrees of freedom; and f) means to activate the movement of said arms.
