Link 5 rotates about axis z-z and is connected by screw pair E to link 2 to which a slotted member with slot a is rigidly attached. Slider 4 moves along slot a and is connected by turning pair D to link 1 which, in turn, is connected by turning pair B to link 3. Link 3 slides in fixed guide p and is connected by turning pair F to link 5. Rigidly attached to link 1 is a circular slotted member x-x which slides along fixed pin A. Tool b can be set up in various positions on link 2. When link 5 is rotated, link 2 is traversed with its slotted member along which slider 4 moves. The motion of slider 4 is transmitted to link 1 which, in turn, transmits motion to link 3, moving only vertically up or down in guide p. Together with link 3, link 5 also has translational motion. Thus nose f of cutting tool b has complex motion along a curve whose curvature depends upon the position where pin A is fixed on the base.
