4. Introduction:
 There are many industrial applications where round bar or square bars
are required to be operated on different machines to make machine
components such as Shafts, Bolts, Screws etc. This needs more and more
number of pieces to be cut for mass production of thosecomponents.
 This prototype model of four-way hacksaw machine which is able to
cut four pieces simultaneously without any jerk and minimum
vibrations. The prototype model implies conversion of rotary motion
into the reciprocating motion for proper working of hacksaw. This
prototype model overcomes the limitations of conventional hacksaw
machines which can cut single piece at a time.

5. Aims & Objectives:
The main objectives of this research work are
 The aim of this project is to design and fabrication of four way
hacksaw blade machine operated by single motor.
 To produce cutting work of parts in more effective way.
 Installing multi hacksaw blades (I.e. 4 in this case)
 To provide alternative for industries aiming toward reducing human
effort and improvement in material handling system.
 Sustainable and practical solutions for the future industrial
environment.
