The fabrication of the die for such job is possible through Computer Numerical Control machines; however it is important to understand that design should incorporate sufficient margins which shall be later addressed through machining. The wheel centre is crucial job piece, as it includes cutting at certain curvatures. It is recommended that the Computer Numerical Control machine should be used for fabrication of the wheel centre with rough units.
The application of the Computer Numerical Control machine is limited to the fabrication and machining of the die. The Computer Numerical Control adopts a simplified approach, where the cutting tool has to be instructed certain positions, the Computer Numerical Control machine will verify that the tool moves to those locations, and during tool movement the programmer has the right to give the feed to the tool. The feed rate of the tool will automatically result in the cutting or grinding operation on the job piece. The machining through Computer Numerical Control machine is therefore simplified and result-oriented.
