The prominent machinery used to produce wheel cover is Injection Moulding Machine. Modern Injection Moulding machine basically comes with integrated system of CAD/CAM. Therefore, CAD/CAM system is crucial to be implemented in this production.
By applying CAD into production, it helps to increase the productivity by reducing time consumed by designer to do synthesis, analysis and documentation of the design. Synthesis can be referred as geometric modelling in CAD function. Geometric model permits the user of the CAD to perform certain operation on the model which includes making new geometric model or modification on existing model takes less time compared to the manual drafting.
CAD is also useful in order to improve the quality of the design where this software permit the designer to do more complex engineering analysis and to consider a large number of options and varieties of design alternatives. Analysis that can be made by applying CAD in design process includes mass properties analysis, interference checking, tolerance analysis, finite element analysis, kinematic and dynamics analysis and discrete – event simulation.
Besides that, design evaluation and review procedures also can be augmented by CAD. The features includes in-evaluating and reviewing a proposed design consist of automatic dimensioning analysis, error checking, animation of discrete – event simulation solutions and plan layout design scores to design the facilities. CAD also helps to improve the design documentations. The graphical output of CAD system results in better documentation of the design than manual drafting where the drawings is superior and has less drafting error and greater legibility.
Finally, CAD eases to create manufacturing database. The documentation includes the product design (geometric specification of product, dimension of the product, material specification, bill of material etc).
