2. Abstract
The motorized multi-operation machine contains three opertions in a single
machine. The three operations are drilling, grinding and cutting. The purpose of
the machine is used for doing all these three operation, instead of using separate
machines such as drilling machine, grinding machine and cutting machine. The
machine operates through motor drive , which paves the ways to carry out all
these three operations exactly at the same time.

3. INTRODUCTION
Multipurpose machining tool setup is made especially for the small scale
industries where labours working are have very little technology. It is a
machine that performs their work quickly and efficiently without the
hassle of using different machines for performing different operations on
workpiece.

4. It has four arms on which four different operations are performed Multi-
operation machine as a research area is motivated by question that arise
in industrial manufacturing, production planning, and computer
control. Consider a large automotive garage with specialized shops.
Industries are basically meant for Production of useful goods and
services at low production cost, machinery cost and low inventory cost.

5. DESIGN CALCULATION
Power P = 382 w
Speed N = 1440 rpm
P = 2πNT/60
382 = 2×π×1440×T/60
T = 2533.21Nm

6. CALCULATION OF SHAFT DIAMETER
Torque T = (π/16) × τ × d3
Shear stress τ = 750 N/mm2
2533.21 = (π/16)× 750 × d3
d = 25.81mm
Standard
diameter = 25.4mm

7. CALCULATION OF BELT LENGTH
Smaller pulley diameter d = 88.9mm
Larger pulley diameter D = 304.8mm
Centre Distance C = 2(D+d)
C = 787.4mm
Belt Length L = 2c+( π /2) (D+d) +( (D-d)2 /4C)
L = 2208mm
Belt Speed V = πdN (60×1000)
V = 1.629ms

8. MACHINING TIME
VTn = c V-Velocity
1.629*(T)1.25 = 175 T-Time
97.74mmin * (T)1.25 = 175
T = (175/97.74)1/1.25
T = 175/97.74
= 1.79 min
97.7 = π*305*N / 1000
= 61.60rpm
Machining = L / f*N L-Length
Machining = 120 / 0.8*61.60 F-Feed
Machining = 2.43 min N-Speed

9. COMPONENTS
Pulley
It is a wheel used to transmit power by means of a belt, rope or chain
passing over its rim.

10. Bearing
Bearing are “parts that assist objects rotation”. They support the shaft that
rotates inside the machinery. Machines that use bearings include auto mobiles,
airplanes, electric generator and so on.

11. V-BELT
A V-belt is a flexible and efficient power transmission device capable of
transferring power from one shaft to another. It is known for its
trapezoidal shape that wedges securely into the sheaves of a shaft.

12. Cutting and Grinding Wheel
Cutting Wheels differ from grinding wheels in their function and structure.
Where grinding wheels use an abrasive to grind large pieces of material off a
workpiece from a shallow angle, cutting wheels typically make narrow, precise
cuts at 90-degree angles.

13. COMPONENTS NAME
1. Frame
2. Motor
3. Shaft
4. Pulley
5. Belt
6. Bearing
7. Drill
8. Nut Bolt Washer
9. Cutting wheel
10. Grinding Wheel

14. PICTORIAL VIEW

15. ADVANTAGES
 Multi operations are performed at one time.
 Size is compact therefore it requires less space.
 Time consumption should be low.
 Less man power is required.
 Low manufacturing and maintenance cost.
 All operations are performed by only one motor.
 High efficient and increase in production.

16. DISADVANTAGES
 Frequency inspection is needed
 It is not suitable for heavy jobs
 It is noisy in operation

17. APPLICATIONS
 It is used in automobiles.
 It is used in small lathe companies.
 It is used in mini workshop.
 It is used in mechanical industries.
 For workers it was helpful to consolidates their basic level of words and also,
they rectify their basic needs and demands.
 This is used for thin metallic material.

18. PROJECT COST
S. No. MATERIAL COST (Rs)
1. Shaft 950
2. L-Angle 2350
3. Pulley 2000
4. Bearing 1100
5. Drill Chuck 190
6. Belt 320
7. Cutting and Grinding Wheel 55
8. Nut, bolt and Washer 200
Total 7165

19. FUTURE SCOPE
 It creates less lead time for production of components, So it is suitable to undergo
diverse manufacturing sectors
 It saves labour cost, so it is adaptable under smart manufacturing
 It really reduces Space occupancy so it is applicable for all scales of manufacturings
 It saves money too
 It is robust in design so overhaul is easy thereby it increases it’s self adaptability for
different ranges

20. CONCLUSION
The multi functional machine is used in the mechanical industries. This
machine operated three operations such as drilling, cutting, and grinding.
So it helps the labours for work easily. So our project member to choose
design the machine. The special of this machine is three purpose takes the
same time and to choose favourable one like drilling or cutting or
grinding.
