The development of a pedal switch hammering machine for forging is an innovative
solution to improve the traditional forging process. This research aimed to design and build
a machine that can deliver accurate and consistent blows to the metal workpiece, reducing
human error and fatigue. The machine is composed of seven major components: the frame,
pedal switch, hammer, pulley system, machine guard, 2hp induction brake motor, and
anvil. The pedal switch mechanism ensures safety and ease of use, while the machine's
design optimizes parameters like hammer blow force and metal temperature. A pedal
switch hammering machine prototype was built and tested to evaluate its performance. The
prototype was tested using three different grades of metal as the working material: mild
steel, 4140, and 4340 round bars. The hammering for each metal was done in two trials
each, and the results were measured, and the following variables were collected: difference
in diameter of the workpieces with every single strike and time needed for the metal to
reach its forging temperature before hammering. Results showed that the machine could
deliver precise and uniform blows to the metal workpiece, reducing human error and
fatigue. The prototype was evaluated by 30 respondents’ experts in forging, industrial, and
mechanical technology and was rated 4.49, with an excellent rating. The prototype was
found to be functional, although it can only be used in small-scale forging operations.
