His book "Parametric Programming for Computer Numerical Control Machine Tools and Touch Probes" has an incredible beginning and held all my interest.

He first excites your curiosity and broadens your general understanding a bit, before digging in. He allows you first to appreciate the power of macro programming and its unlimited uses, and then /5(7).

Numerical control (also computer numerical control, and commonly called CNC) is the automated control of machining tools (such as drills, boring tools, lathes) and 3D printers by means of a computer.A CNC machine processes a piece of material (metal, plastic, wood, ceramic, or composite) to meet specifications by following a coded programmed instruction and without a.

To determine the problems of DNC a research program was initiated to control three machine tools by digital computer. The system of control was different for the three machines, and was composed of a machining centre with GE control, a milling machine with ICON control and a lathe — retrofitted with electrohydraulic pulse motors.

The computer Cited by: 5. Numerical Control of Machine Tools. book. unique. insofar. covers. all. three. A computer numerical control (CNC) machining system. Numerical control involves using control devices that can automate the operations of the machine tools in industrial environments.

These machines can be manual or completely automated. Over the last few decades, the trend has been towards the use of Computer Numerical Control (CNC) devices that are fully automated control machines. Countless CNC Computer Numerical Control machine tools & machines can run unattended during the course of their whole machining cycle, freeing the operator to handle other tasks.

This gives the CNC user more than a few extra benefits such as reduced operator tiredness, fewer mistakes caused by human error, and dependable and foreseeable.
