Abstract
Devices adapted to position exactly a workpiece and a machine tool for machining the workpiece to create a shaped article that conforms to a specification therefor. The device for positioning the workpiece includes a rotary table in which the workpiece is held so that it can be machined in the round by the tool. The table is turned by a slider that is driven by a stepping motor and is reciprocated by a pair of drums which are linked by flexible metal bands to opposite ends of the slider. When the motor causes the drums to rotate clockwise, the slider is then pulled in one direction by the bands, and when the drums are caused to rotate counterclockwise, the slider then advances in a reverse direction. A similar device serves to exactly position the machine tool.
