Abstract
Aimed at the design and fabrication of an electric hacksaw from locally
sourced materials, the study commenced with a literature review of the past
works on hacksaws, starting from historical perspective of electric hacksaws to
their ergonomics features. The design which began with the slider crank
calculation gave the following results: the acceleration of the slider, Fp of
418.65mm/
, the angular acceleration of the connecting rod,
of -40.93mm/
, the cutting force required to cut a high speed steel of 1mm
thickness and hardness of 60HRC as 10.67kN, as well as 5.42kWatts as the power
required to drive the hacksaw blade. Due to its numerous advantages which
include cost effectiveness, weldability, ductility, recyclability, etc., steel
was mainly adopted in material selection during the fabrication of the electric
hacksaw. Driven by 150watts and 100 rpm electric motor, the electric hacksaw
with an incorporated blade was designed and fabricated to be robust, effective,
and user-friendly. With a total pocket-friendly cost of two hundred Dollars, the
electric hacksaw was later tested for safety and durability before painting.
Recommendations were also made on the operation and parameters of the machine,
before suggestions were offered on overall machine performance, optimization,
as well as further improvements on the machine.
