Abstract
An attachment for cutting machine tools, such as band saws, spindle-shapers, sanders and the like, controlling the feed path of the workpiece to the cutting tool to form desired workpiece contours, such as circles, arcs and the like, has a grooved track bar easily locked on and removed from the machine bed or table carrying a slide in the groove which has a workpiece centering pivot pin projecting therefrom. A workpiece is either directly pivoted on the pin or secured to a templet pivoted on the pin and is rotated about its pivot support against the cutting tool. The slide may be locked in the groove at a selected distance from the tool, may be pushed against a stop at a selected position in the groove or may be shifted by a cam to control the feed path of the workpiece for forming desired contours. Circles of selected diameters, elipses of selected minor and major radii, heart shapes, four leaf clover shapes and the like are easily developed.
