Industry standard protocols
Does anybody know about the standards used for the files to control the CNC machines? ISO standard??
- The simple answer is that there is no Standard. There are a couple of areas where there is an approximation of one.
- Since the mid 1980s, the Electronics Industries Association (EIA) has published RS-494. It is a multi-part specification and has been partly adopted by the IEEE. This is probably closest to an industry standard.
- ISO has only ISO/IEC 9506, Industrial automation systems - Manufacturing Message Specification which deals more with headers and encapsulation.
- ISO also has ISO 10303, Industrial automation systems and integration - Product data representation and exchange, but this deals more with specs for the part being machined, while NC wants to look at the steps needed to machine it.
- Sorry I can't get you a clear answer. The are a number of semiproprietary software solutions based around the RS-494 specification. --Lou I 15:02, 15 Sep 2003 (UTC)
- The G-Codes are standardised in ISO 6983.
- The newer ISO 14649 offers a feature based alternative.
- ISO 14649 has been incorporated into STEP (ISO 10303) as the ARM for ISO 10303-AP238.
