Design and Implementation of a Three Dimensional CNC Machine

This paper discusses the design and implementation of low cost three dimensional computerized numerical control (CNC) machines for Industrial application. The primary function of this microcontroller based CNC machine is to cut the metal in to required shape. This discuss is focused on communication between Personal computer (PC) and a numerical control machine. The objective to devise a computer controlled cutting machine arose from increasing demand for flexibility and cutting with respect to edge quality. The system has an 8 bit microcontroller based embedded system to achieve cost effectiveness and also maintains the required accuracy and reliability for complex shapes. The backbone of the system is a cleverly designed mechanical system along with the embedded system resulting in accuracy. The system uses C# as a programming language and .NET platform for user interface.
