Abstract:
A machine tool for machining workpieces by motion of a machining tool relative to the workpiece comprising:(a) a worktable having X and Y axes and adapted to support a workpiece thereon; (b) a support extending above said worktable in one axis and movable along the other axis of said worktable; (c) first machining tool mounting means movably mounted on said support for movement along said support in said one axis; (d) second machining tool mounting means movably mounted on said first machining tool mounting means for movement in said other axis relative to said support within a range of motion; (e) a machining tool mounted said second machining tool mounting means; (f) first drive means for said support to move said support in said other axis over said worktable; (g) second drive means for said first machining tool mounting means to move said first machining tool mounting means in said one axis along said support; (h) third drive means for moving said second machining tool mounting means in said other axis relative to said first machining tool mounting means; and (i) a computer control for effecting operation of said first and second drive means to move said machining tool in one and other axes and for effecting operation of said third drive means for rapid movement of said machining tool in the other axis to machine a workpiece supported on said worktable.
