A shaper machine produces flat surfaces on workpieces by moving a cutting tool in a straight line using a ram. The ram moves the tool forward for the cutting stroke and backward for the return stroke with no cutting during the return stroke. A shaper can produce horizontal, vertical, or inclined surfaces, as well as grooves, slots, and steps. The main components of a shaper are the base, column, table, cross rail, ram, and tool head. Shapers are classified based on their ram driving mechanism or orientation and include crank, geared, hydraulic, horizontal, and vertical shapers.

2. A SHAPER MACHINE
• Shaper is Machine tool which produces flat surfaces in horizontal,
vertical or inclined planes depending upon the orientation of the
cutting tool.

3. FEATURES
 In shaping machine the ram moves the cutting tool is
backward and forward direction in a straight line.
 Forward motion is called cutting stroke and backward motion
is called is called return stroke.
 no cutting during return stroke.
 it can also produce concave and convex surface.

4. PARTS OF A CRANK SHAPER
 Base
 Column
 Table
 Cross Rail
 Ram
 Tool head

5. SHAPER MECHANISM

6. OPERATION ON SHAPER:-
Basic operation on shaping machine can be classified as-
 Horizontal cutting
 vertical cutting
 Inclined cutting
 Grooved
 Slotted
 Stepped

7. TYPES OF SHAPER MACHINE:-
1.The Acc. to the ram driving mechanism
 Crank shaper
 Geared shaper
 Hydraulic shaper
2. Acc to the position & travel of ram
 Horizontal shaper
 Vertical shaper
3. Acc to the direction of cutting stroke
 Push Type shaper
 Draw type shaper
4.Acc to the design of the table
 Standard shaper
 Universal shaper

8. SPECIFICATION OF SHAPER:-
 Maximum ram stroke= 700mm
 Maximum tool overhang =840mm
 Max. distance b/w table surface and ram = 400mm
 Min. distance b/w table surface and ram = 80mm
 Dimension of table working surface = 700×450mm
 Max. horizontal travel of table=700mm
 Max. vertical travel of table= 320mm
 Motor power = 7kw
 horizontal feed = 0.25-5mm
 Overall dimension= 2780 ×1750×1780mm

9. SHAPING TIME ESTIMATION
L: length of stroke in meters
N: number of stroke per minutes
Distance moved by the shaper
tool per mnt. =LN
Cutting stroke/return
stroke=3/2
Cutting time/total
time=3/5

10.  Cutting speed=(5/3)LN
 total no. of stroke required to complete a job(St)=W/F
(where W=width of the workpiece)
L=length of stroke
Vo=cutting speed in m/min
Vr=return speed in m/min
f =feed per cycle in m.
 cutting stroke(to)=L/Vo
 return stroke(tr) =L/Vr
 number of cycles = W/f
 total time for one cycle(T)=to+tr
MACHINING TIME(Tm)=NO.OF CYCLE×TIME PER CYCLE
Tm=(W/f).T
