CNC milling machines generally input and output data through the RS232C interface, including machining programs and machine tool parameters. When the executed processing program exceeds the storage space, DNC processing should be adopted, that is, the external computer directly controls the CNC milling machine to process.

Both machining and grinding processes follow the basic principle of subtractive manufacturing approach. Here layers of excess material are removed from a solid 3-D blank to obtain final product. On the contrary, in additive manufacturing approach, layer by layer material is added one over another to build a solid 3-D product.

A sequence ...

Guards on grinding machines are particularly important for ensuring operator safety. Grinding wheels seldom burst, but when they do, there is a great risk of serious injury to the machine operator. Recent studies suggest, however, that the enclosures commonly used in gear grinding machines, for example, could be overdesigned at present.
