There is no European counterpart to the Air Force sponsorship of the initial development at MIT of numerical control and the APT system for part programming, coupled with the large-scale purchases of numerical control equipment for use in the aerospace industry. European developments, being primarily company-sponsored, are therefore simpler and on a smaller scale, and frequently directed toward a single family of machine tools with programming systems processed on small- or medium-scale computers. The APT System, which is now as much a de facto standard for this field as FORTRAN was for its field, is a general system developed to program the entire range of existing numerical control hardware. A subset -- ADAPT -- was also sponsored by the Air Force to extend this standardization to a system which could be run on medium-scale computers. The USASI X3.4.7 APT Standards Working Group is now attempting to propose an American standard for the APT language and its several subsets. In Europe, the majority of user-developed programs are used in the plants of each developer and not exchanged among users, although exceptions do exist, as in the case of systems developed by Ferranti and Olivetti. In addition, ADAPT and AUTOSPOT (an IBM point-to-point system) are used when American computers are available. The APT system was introduced in Europe in late 1964, and 16 of the more than 90 organizations participating in the APT Long Range Program run by the IIT Research Institute are European. The National Engineering Laboratory in Scotland is developing the 2CL language, and in a joint effort, the Technical Universities of Berlin and Aachen, with Siemens, are developing the EXAPT language. Both of these are intended to be upward compatible with the full APT language. These inputs, combined with those from the US effort, are the province of a new Numerical Control Subcommittee within the International Standards Organization Technical Committee 97/WGa on Programming Languages, which will meet for the first time in Paris in November, 1967. These developments provide an excellent example of international cooperation in programming language development in an important and growing application area. in ACM Computing Reviews 8(06) November-December 1967 view details in Leslie (ed) Numerical Control Programming Languages 1969 (PROLAMAT 69) view details in Leslie (ed) Numerical Control Programming Languages 1969 (PROLAMAT 69) view details |
