Base :It consists of a heavy robust cast iron -structure that supports all the other parts of the machine.

Column: It acts as a housing for the electrical circuits and operating mechanism of a shaper.

Cross-rail:  It is a heavy cast iron body attached to the column of a shaper machine. It is used for two purposes:  for elevating the table and for cross traverse the table.

Ram:  It is the reciprocating pan of the shaper and carries the shaper head in front of it. The reciprocating motion of the ram takes place on accurately machined guide ways on the top of the column. It gets its drive from the quick return mechanism, which is fitted inside the column to change its position relative to the job.

Tool head :  it is used for holding the tool rigidly.

Shaper head : it consists of a tool slide, tool post,  and clapper box and is clamped firmly to the front of the ram. It has a vertical feed screw for the vertical movement of the tool. The vertical movement can be measured accurately by means of a micrometer dial near the handle .The head can be swiveled to any angle to enable the tool to take angular cuts and for cutting from the sides of the job. It also consists of a tool holder that rests on a clapper box. The clapper box is fastened to the front of the shaper head slide and is free to point forward and fit on a taper pin which holds it in place. This provision is made in order to prevent the cutting tool from damaging the work during the idle stroke.
