Shaping Machine Operation :

 The main functions of shaping machines are to produce flat
surfaces in different planes. Fig. shows the basic principle of generation
of flat surface by shaping machine. The cutting motion provided by the linear
forward motion of the reciprocating tool and the intermittent feed motion
provided by the slow transverse motion of the job along with the bed result in
producing a flat surface by gradual removal of excess material layer by layer
in the form of chips. The vertical infeed is given either by descending the tool
holder or raising the bed or both. Straight grooves of various curved sections
are also made in shaping machines by using specific form tools. The single
point straight or form tool is clamped in the vertical slide which is mounted at
the front face of the reciprocating ram whereas the workpiece is directly or
indirectly through a vice is mounted on the bed.

Main Application Of Shaping Machine ;
It is already mentioned that shaping machines are neither productive nor
versatile.
However, its limited applications include :
  • Machining flat surfaces in different planes. Fig.  shows how flat
    surfaces are produced in shaping machines by single point cutting
    tools in

 (a) Horizontal, 

(b) Vertical and 
(c) Inclined planes.
  •  Making features like slots, steps etc. which are also bounded by flat
    surfaces. Fig. visualises the methods of machining
(a) slot,
(b)
pocket
(c) T-slot and 
(d) Vee-block in shaping machine by single
point tools.

  • Forming grooves bounded by short width curved surfaces by using
    single point but form tools. Fig.  typically shows how
 (a) oil
grooves and 
(b) straight tooth of spur gears can be made in shaping
machine

  • Some other machining applications of shaping machines are cutting
    external keyway and splines, smooth slitting or parting, cutting teeth. of rack for repair etc. using simple or form type single point cutting
    tools.
    Some unusual work can also be done, if needed, by developing and
    using special attachments.

However, due to very low productivity, less versatility and poor process
capability, shaping machines are not employed for lot and even batch
production. Such low cost primitive machine tools may be reasonably used
only for little or few machining work on one or few pieces required for repair
and maintenance work in small machine shops.
Keyway Cutting
 
Keyway cutting on shaper is complete by holding work piece in a vice through using a V-block.
The axis of shaft is set parallel to movement of stroke by the help of dial indicator. The
position of shaft is done by dial indicator as of top with the side of shaft. Keyway cutting
process is carrying out just similar to cutting groove on shaper. The major dissimilarity among
groove cutting and keyway cutting lies in the way of holding the work piece.
