Solutions such as WorkNC, Powermill, Tebis, HyperMILL, TopSolid are using their own generators. Today modern CAM software uses their own technology postprocessor. But I think it is too based on the APT technology. I really appreciate your post on the post processors. Send me an e-mail at NCDataServices web site. I also have the documentation for the CATIA variant of the SCL format that I can send you. I also have the documentation for the MasterCAM NCI that I can send you. MasterCAM NCI to APT SCL converters are available. This makes writting postprocessors for all CAM systems interesting! You are looking for the “ANS X3.37 -1993 Programming Language APT” standards documentation Chapter 4 “APT OUTPUT DATA” Chapter 4.1.3 “SOURCE CLDATA (SCL)”.I have this document and can e-mail you a copy of this section.Each CAM vendor has thier variant of this standard (CATIA, UG-NX, ProE, SurfCAM, etc.) then MasterCAM has thier own totaly different output format (NCI). It contains the APT programming language not the Source CLfile standard (SCL). The APT manual will not have what you are looking for.
The standards are public domain, but you would have to pay to get a copy from the Gov’t. I also have hard copies of some of the standards (I was an IBM rep.). Modern Machine Shop used to publish a list of these NC specific stardards by number. The American National Standards Institute (ANSI) and the Electronics Industries Association (EIA). Howdy!When I started this blog I knew it would be hard to update it in an often basis but I didn’t know it would be so hard! Hello Anders,There are two standards groups that have been responsible for setting the standards for the APT Language and the NC machine code (M&G).
