Abstract
Trophy is an object that give for a winner in a competition. It comes in many
types and in different shape. It is started from ancient Greece where it given for a winner
in a war and be design with the details of the war. In traditional way, they create this
trophy by using hand. They create the trophy on the wood and even create it on the
stone. Making a trophy by using hand takes a lot of time to produce it. With the
technology that available in this world, reverse engineering technique is applied to the
existing objects then innovate it become something new. Reverse engineering
technique is most popular technique that use to create another products that similar to
the existing object without having any original document or measurement from the real
products. Then by using a 3D scanner it can digitalizing physical objects to create 3D
computational geometry. 3D scanners used to capture real object and makes another
one in the same shape so that they can be remodeled or analyzed in the digital world.
This 3D scanner is the fastest, most accurate, and automated way to acquire. From that
can get all the data needed and can improve the actual design to a better design. The
object can be modified in the CAD model to correct imperfections and do the
improvement by using the suitable software such as CATIA software. CATIA software
can provide a surface model or the more complex solid model, whichever results are
needed for the application. By using CNC machining to produce the products it can
reduce the time taken besides can produce a better surface quality. In this project, the
products are choose based on some criteria then it will also undergo with the technique
of reverse engineering and producing by using CNC machine. . Then, the parameters
of the produced product by using reverse engineering technique will be compared with
the design of existing product. Besides, the dimension and size of machining part also
be tested. For the parameters comparison result between the outcome product and
design of existing product, it contains 5 distance that has been registered to be measure.
The percentage different for Distance 1, Distance 2, and Distance 3, Distance 4 and
Distance 5 are 4.20%, 5.63%, 8.95%. 0.17% and 0.09% respectively.
