Link 3 rotates about fixed axis x-x and is connected by screw pair E to link 4 which has extension d. Link 4 is connected by turning pair C to link 1 which, in turn, is connected by turning pair D to link 2. Link 2 turns about fixed axis B. Rigidly attached to link 1 is a circular slotted member in whose slot e pin a of link 5 slides. Link 5 slides in guide p of link 4. Tool b can be set up in various positions on link 5. When link 3 is rotated, link 4 with its rigidly attached extension d is traversed along axis x-x. Link 5 with tool b slides in a direction perpendicular to axis x-x. The shape of the curve described by nose f of tool b is varied by adjusting pivot D of link 2 along the axis of link 1.
