Computer controlled machines for automatic production

The term "computer numerical control (CNC) technology" encompasses all machines with CNC operating systems. CNC technology includes all machines with a computer numerical operating system. Since the beginning of the 1980s there has been no numerical control (NC) technology available and so the difference between NC and CNC technology is no longer debated; the terms are now used synonymously.

Computer operated machines for automatic production

CNC technology is identified through its free programmability of motion sequences that can be adjusted through saving and changing the CNC programme as needed. DIN 66025/ISO 6983 defines an interface for programming supported by all CNC machines, which covers the whole system and does not depend on the manufacturer. Complex CNC machines contain an additional or alternative programming interface, that allow complicated motion sequences to be easily programmable. An additional interface translates the programme inputted by the operator into a DIN code. The alternative interface can then function completely independently of this standard.
CNC technology in use
The programming of the workpiece sets up the control information for the manufacturing of a workpiece in a database. The programme data is created offline in the planning department and transferred to the machine via a cable or external disk. With online or workshop programming, the inputting of the programme occurs directly on the machine. The creating of workpiece programmes can be conducted with special programming language particularly suited for manufacturing technology like APT and EXAPT from CAD data or drawings. To directly transfer data from the CAD system, data transfer systems like IGES are available. The source text of the workpiece programme is translated over the CLDATA interface into Cutter Location Data. This is data used to direct the positing of the tool belonging to the NC machine. This data can be translated into a DIN code or is translated by the machine itself in real time. The direct numerical control (DNC) interface makes the controlling of CNC machines using an external computer possible.

The history of CNC technology

CNC Technology 02
CNC technology was developed from numeral control for manufacturing technology. It was invented at MIT at the beginning of the 1950s. It replaced the hard-wired logical operations of NC technology by introduction a free programmable computer. It replaced all the older technology within 5 years of being on the market. With NC technology the control information could be read directly from a punched tape. CNC technology only uses these types of external saving mechanisms for transferring data or archiving. CNC programmes are loaded onto an internal memory or directly applied. Nowadays, CNC technology is implemented in all stationary machine tools. It is the basis for all fully automatic production processes, for example, in machining centres.

Who produces CNC technology?

The production of CNC technology is available from (among others) BIESSE, CMS, HEIDENHAIN, HOMAG, MORBIDELLI, SINUMERIC and WEEKE.
