The document outlines the development of a modernized four-way hacksaw machine utilizing a scotch yoke mechanism to enhance cutting efficiency of various materials like PVC, metal, and wood, while simplifying mass production. A literature survey references existing research on multipurpose machines and efficient cutting methods, highlighting the need for reduced human effort and material selection for better performance. The project aims to fabricate an automated model capable of cutting multiple materials simultaneously, improving upon traditional hacksaw machines, making it suitable for small industries and workshops.

2. OBJECTIVE:
 To develop a modernised four way hacksaw machine
based on Scotch Yoke Mechanism.
 It will use a less effort to produce uniform cutting of
PVC pipes, Metal bars , Wood.
 Also fulfils the need of more material cutting account
to mass production.

3. Literature Survey
 Dharwa Chaitanya Kirtikumar:- In this paper we have
studied about the designed and developed
multipurpose machine which does not require
electricity for several operations this is a human
powered machine runs on chain drives mainly with
human efforts.
 R. Subash , K Samuel Jayakaran :- The objective of the
paper is using the conventional mechanical process
which plays a vital role. The main aim is to reduce the
human effort for machining various materials such as
wooden blocks, steel, PVC, etc.

4.  Prof. Nitinchandra, R. Patel, Ravi Thakkar:-
In his paper “Material Selection And Testing Of hacksaw
Blade Based On Mechanical Properties” stated that the
appropriate saw blade must be selected for better operation
and fine cutting by selecting number of teeth per inch.
 D.V.Sabarinanda, V.Siddhartha, T.Mohanraj in their
paper “Design and Fabrication of Automated Hacksaw
Machine” (April 2014) gives an idea about the various
components required for fabrication of the proposed model.
These components will help to get smooth working condition
and future automation of different mechanical actions as well
as linkages.

5. Methodology
 Scotch Yoke Mechanism:-
The Scotch Yoke Mechanism also known as slotted
link mechanism is a reciprocating motion mechanism
converting the linear motion of a slider into a rotational
motion or vice versa.

6.  Proposed Methodology

7.  This project consists of single phase vertical electric motor
rigidly placed at the centre of metallic foundation provided.
The circular disc is mounted on the shaft of motor with the
help of key and key slot arrangement. The eccentric point
on the plane of disc is provided such that the desired cutting
stroke is achieved (around 4-5 inches).
 Machine Components:
 Base (Foundation)
 Hacksaw Frame
 Hacksaw Blade
 Guide Ways
 Crank Wheel
 Holding Vice
 DC Motor
 Supporting Blocks

8.  Work Plan
 Study and selection of mechanisms according to the
specific functions of machine.
 CAD modelling of proposed design by using solid
works.
 Define approximate or appropriate dimensions of
elements of model.
 Select suitable material for it.
 Modify dimensions of assembly for fabrication.
 Fabrication of base frame using welded and bolted
joints.
 Assembly of all major components and power housing

9. EXPECTED OUTCOME
This model will overcome the limitations of conventional
hacksaw machine which can cut only single piece at a time.
It will be able to cut different metal bars and wooden bars
simultaneously and will be helpful in many small scale
industries , domestic work and workshops due to its
compatibility, reliability and efficiency at affordable price.
