A, shaper by nature is a slow machine, because of its straight line,forward and return(idle) stroke. The single point tool requires several strokes to complete a work.
The cutting speeds are not usually very high since difficulties are encountered in designing machine tools with high speeds of reciprocating motion due to high insertia forces developed in the motion of the units and components of the machine. owing to these developed in the motion of the units and components of the machine. owing to these reasons the shaper does not find ready adaptability for assembly and production line.
