unnecessary  space  where  some  students’  handwriting  are  varied  from  each  other  and  uniformity
             cannot be achieved.
                  Our development for the Easy Metal Stamper must be aligned with the following objectives
             in order to counter the problems faced. First, the objective of the project is easy handling, to mark
             with more than one (1) puncher at a time. Second objective of the project is proper finishing, making
             proper finishing on the metal plates with readable and uniform imprint with minimum imprint’s depth
             of 0.02cm. Last objective is user friendly, to produce a machine that is suitable for the use of students
             and able to ensure the safety of the users by installing hardware that can increase the safety features of
             the prototype.
                  To enable work on the project to run smoothly and will not deviate from the original purpose
             of the project, we had set up a number of scopes to be met. The scopes or limitations of this project
             are as follows; i) the project aimed to be used on flat metal plates with thickness of 2mm  – 6mm
             within the size of 100mm × 100mm. ii) the project must be able to imprint carbon steel type metal
             plates according to the specified dimension. iii) the project will be included with electronic equipment
             such as microcontroller that is able to control the speed of DC motor, a buzzer, proximity sensors for
             metal detection and switch box that will enhance the safety feature of the prototype.

             Purpose of the Project
             The  results  of  this  project  are  expected  to  provide  convenience  to  students  in  carrying  out  the
             stamping  work  on  the  practical  welding  task.  Marking  the  workpiece  will  be  faster  by  students
             compared to previous procedure where the work is done by single imprint at a time. Furthermore,
             stamping work using this metal stamper make the plates readable and uniform imprint which allows
             lecturers to identify and give marks to each student who carry out the practical task.

             Methodology
             Methodology  of  this  project  is  divided  into  six  elements  shown  in  the  figure  1  below.  All  these
             elements can be tied to each other to get the spot of the Easy Metal Stamper that can guarantee quality
             and aim at objectives.
                  The problem arises during the marking of the welding plates by the students once they are
             done with their task. The current method that is being used to mark their metal plate is by using paint
             marker or some may use a hammer with punchers. By using such methods, we have found out that
             there were safety concern arises where students often hurt themselves from accidently t ouching the
             hot surface of the metal plates.
                  Aside than that, the usage of paint marker is not efficient because most paint marker’s tip
             ended up ruined because most student will not wait for their metal plate to cool completely and will
             simply write down their name and ruined the tip of the marker
                  After the problem is recognize, we do the literature review or background research how to
             marking  the  metal  easier  and  what  product  is  already  existed  in  industry  market.  However  in  the
             market, the stamping product is too expensive and not practical to use by students in the workshop of
             Polytechnic Mukah.
