5. Materials required
Frame
Spray Paint
Hacksaw
Slider Mechanism
Crank Shaft
Solar Panel
Mini Vice
12V Dc Gear Motor

6. Materials specification
Hacksaw Frame:
We will use hand hacksaw to cut the material with
the help of power we are getting from the motor.
Approx. cost of the Hacksaw frame is 50 to 100 ₹

7. Materials specification
Crank and slider mechanism :
Acrankshaftis a mechanical component used by in
apiston engineto convert thereciprocating
motionintorotational motion or rotational motion
into reciprocating motion.
Approx. cost of this mechanism is 500 ₹

8. Materials specification
Solar Panel:
When the sun shines onto a solar panel, energy from
the sunlight is absorbed by the PV cells in the panel.
This energy creates electrical charges that move in
response to an internal electrical field in the cell,
causing electricity to flow.
Approx. cost of the Solar is 1500 ₹

9. Materials specification
12V Dc Gear Motor:
The DC motor is the motor which converts the direct
current into the mechanical work. It works on the
principle of Lorentz Law, which states that “the
current carrying conductor placed in a magnetic
and electric field experience a force”.
Approx. cost of the Motor is 1500 ₹

10. Materials specification
Limit Switch:
The term limit switch is derived from the operation
of the device it-self.As an object (or target) makes
contact with the operator of the switch, it
eventually moves the actuator to the "limit" where
the elec-trical contacts change state.
Approx. cost of the Switch is 50 to 200 ₹

11. ADVANTAGES
I. Time saving as compared to simple hacksaw
II. Money saving as it operated by Solar Energy
III. Easy machinery used
IV. Comfortable then ordinary hacksaw
V. It is portable

12. DISADVANTAGES
Without human effort it’s not operated
Work only on Sunny Days only
Not fit for heavy production

13. APPLICATION AREAS
It could be used wherever metal cutting is
done in small scales, including at small
industry and furniture units Etc.

14. FUTURE SCOPE OF THE PROJECT
•The machine can solve the problem of time
consumption.
•Waste of resources in the face of labour
costs is reduced.
•The machine can be used in the small
industry where it is manufactured, in the
packaging sector.
•It generates sustainable and practical
solutions for future industrial development.
