CNC also known as computer routing, CNCCH or NC machine tool is actually HongKong there's a term, then was introduced into China, the pearl river delta is CNC milling machine, and in other area to be called “CNC machining center” a kind of mechanical processing, is a new processing technology, main job is processing program, the original manual work to computer programming. Scilicet, manual processus experientia requiritur.

In CNC Lathe processus, determinatio processui itineris plerumque sequitur principia ostensum est quod infra:

1.The accurate et superficiem asperitas workpiece sit praestati.

II. Fac brevissimam processus itineris, reducere inanis peregrinatione tempus, amplio processus efficientiam.

III. Try ad simpliciorem in workload de numero calculation et machining ratio.

IV. SUBROTINES debet adhiberi aliquam repetita programs

CNC dispensando habet sequenti commoda:

1.Greatly reducere numerum tooling, processus of complexu figura partes non opus universa insolens. Si vis mutare figura et magnitudine partes, tantum postulo ut modify partes processus procedendi, idoneam novum productum progressionem et modificatio.

II. Stabilis processus qualitas, princeps processus accuracy, princeps repetitio accurate, in occursum de requisitis aircraft processus.

III. Productio efficientiam est altior sub conditione multiplex varietatibus et parva batch productio, quae potest reducere tempus productio praeparatio, machina tool temperatio et processus inspectionem, et redigendum tempus ex usu est optimum secans.

IV. Potest aliquid processus complexu quod difficile est processionaliter per conventionales modi, et potest etiam processus aliquas partes, quae non servetur.

Incommodum CNC machining est quod sumptus of apparatus instrumenta et apparatu est pretiosa, et sustentationem curatores non requiritur ad altiorem gradum.
