The project was made based on the specification that has been set. Maximum number of
puncher that gives uniform and clear imprint is 4 punchers in a row. If we applied more than 4
punchers at a time it will cause ununiformed imprint. During the test run conducted, there were zero
casualties. The strengths of the prototype are: i) Use lesser energy to operate by using a
microcontroller; With the installed start push button and DC motor that is use to lift the weight, user is
able to lift the weight multiply times without having to manually lift it. ii) Portable; the prototype is
not stationary thus can be moved around. iii) Have multiple safety features; with the use of buzzer and
proximity sensors these enhance the safety features of the prototype when it is being used. iv) Easy to
use; with it simple and interactive mechanism such as the use of LCD screen, user is able to operate
the machine with ease. The assembly of the project as shown in Figure 5:

Conclusion and Recommendation
From the test run result and satisfaction survey this project is successful. Our project was able to
achieve desired objectives which are developed a prototype that is to mark multiply punchers at a
time, leave desirable imprint on the metal plates and generate rapid movements with the help of the
DC Motor. This project make students easier and faster during workpiece stamping process and it
give the best result of imprint.
Based on the discussion and conclusion of the project outcomes, there are some suggestions
that can be done in order to improve the prototype. Several recommendations are; i) expand the base’s
width to enhance the stability and reduce vibration during stamping process. ii) Enhance the safety
features by adding cover to necessary parts of the prototype; e.g.; the weight, metal slider. iii)
Improve the design of the metal slider by adding an appropriate handle for easy and safer handling iv)
Improve the design of the metal slider so that it can be use on multiply types and size of metal.
