Shapers are mainly classified as standard, draw-cut, horizontal, universal, vertical, geared, crank, hydraulic, contour and traveling head, with a horizontal arrangement most common. The depth of the cut increments by moving the workpiece, and the workpiece is fed by a pawl and ratchet mechanism. The return is governed by a quick return mechanism. In a standard shaper, cutting of material takes place during the forward stroke of the ram and the return stroke remains idle. The ram reciprocates and the cutting tool, held in the tool holder, moves forwards and backwards over the work piece. The table may be supported at the outer end. The work piece is rigidly held in a vise or clamped directly on the table. Adding axes of motion to a shaper can yield helical toolĪ single-point cutting tool is rigidly held in the tool holder, which is mounted on the ram. The ram is typically actuated by a mechanical crank inside the column, though hydraulically actuated shapers are increasingly used. Its cut is analogous to that of a lathe, except that it is (archetypally) linear instead of helical.Ī wood shaper is a functionally different woodworking tool, typically with a powered rotating cutting head and manually fed workpiece, usually known simply as a shaper in North America and spindle moulder in the UK.Ī metalworking shaper is somewhat analogous to a metalworking planer, with the cutter riding a ram that moves relative to a stationary workpiece, rather than the workpiece moving beneath the cutter. In machining, a shaper is a type of machine tool that uses linear relative motion between the workpiece and a single-point cutting tool to machine a linear toolpath. Machine tool which linearly cuts or grinds the workpiece Shaper tool slide, clapper box and cutting tool Shaper with boring bar setup to allow cutting of internal features, such as keyways, or even shapes that might otherwise be cut with wire EDM.
