Working Principle of Shaping Machines
Working Principle of Shaping Machines - The tool held in the tool holder mounted on the ram moves forwards and backwards in a straight line over the work piece rigidly held in a vice clamped over the work table.
Each time the tool moves forward it cuts a sliver of metal from the workpiece. Each time the tool moves backward the tool lifts clear of the workpiece.

The work remains stationary during the forward (cutting) stroke of the tool but moves across by one cross traverse increment during the return (non cutting) stroke. The appearance of the machined surface is of a succession of closely straight line cuts.
