APT (Automatically Programmed Tool) is a high-level computer programming language most commonly used to generate instructions for numerically controlled machine tools. Douglas T. Ross is considered by many to be the father of APT: as head of the newly created Computer Applications Group of the Servomechanisms Laboratory at MIT in 1956, he led its technical effort. APT is a language and system that alleviates the tedious mathematics of writing toolpaths for numerically controlled equipment. This early language was used widely through the 1970s and is still a standard internationally. Derivatives of APT were later developed. (en) APT (Automatically Programmed Tools) ist eine anwendungsbezogene Programmiersprache zur Erzeugung von Steuerungsinformationen für Werkzeugmaschinen. APT wurde in den 1950er Jahren in den USA entwickelt und in Fortran IV codiert, um komplexe Fertigungsaufgaben für NC- und CNC-Fertigungsmaschinen problembezogen beschreiben zu können, z. B. an Flügelanschlüssen im Flugzeugbau. APT erlaubt primär eine Bearbeitungs-Geometrie-Beschreibung, hat jedoch in vielen APT-Dialekten auch technologische Erweiterungen erfahren. Eine der bekanntesten Erweiterungen ist EXAPT, "EXtended Subset of APT". Der EXAPT-Verein gründete sich in den 1970er Jahren in Deutschland an den Universitäten Stuttgart und Aachen mit Einbezug Industrie-Unternehmen wie EXAPT Systemtechnik GmbH, um die APT-Sprache weiterzuentwickeln. (de) L'APT (Automatically Programmed Tools) è un linguaggio di programmazione di macchine utensili a controllo numerico; consente lavorazioni bi-tridimensionali e contornature fino a cinque assi. È stato realizzato dal Massachusetts Institute of Technology (MIT) su commissione della Aerospace Industries Association (AIA) degli Stati Uniti d'America. Il sistema è basato sulla definizione geometrica del pezzo da lavorare, sulla definizione dei movimenti dell'utensile necessari per la lavorazione e sul calcolo automatico della posizione dell'utensile. Il programma detto Part-program, elaborato dal Processor, produce il file CLF (cutter location file) scritto in formato intermedio. Questo file, rielaborato dal Post-processor, produce il programma di lavoro scritto nel codice compreso dall'unità di governo della macchina utensile (ISO Standard). Il linguaggio comprende più di 300 parole riservate. (it) |
