ISO 10303-242 is also called the STEP Application Protocol 242 (STEP AP 242, for short). The intent of STEP AP 242 is to support a manufacturing enterprise with a range of standardized information models that flow through a long and wide \u201cdigital thread\u201d that makes the manufacturing systems in the enterprise smart. One such standardized information model is that of tolerances specified on a product\u2019s geometry so that the product can be manufactured according to the specifications. This paper describes the attributes of smart manufacturing systems, the capabilities of STEP AP 242 in handling tolerance information associated with product geometry, and how these capabilities enable the manufacturing systems to be smart.<\/jats:p>","DOI":"10.1115\/1.4029050","type":"journal-article","created":{"date-parts":[[2014,11,10]],"date-time":"2014-11-10T19:04:24Z","timestamp":1415646264000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":68,"title":["A Portrait of an ISO STEP Tolerancing Standard as an Enabler of Smart Manufacturing Systems"],"prefix":"10.1115","volume":"15","author":[{"given":"Allison Barnard","family":"Feeney","sequence":"first","affiliation":[{"name":"Systems Integration Division, Engineering Laboratory, National Institute of Standards and Technology, Gaithersburg, MD 20899 e-mail:"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Simon P.","family":"Frechette","sequence":"additional","affiliation":[{"name":"Systems Integration Division, Engineering Laboratory, National Institute of Standards and Technology, Gaithersburg, MD 20899 e-mail:"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vijay","family":"Srinivasan","sequence":"additional","affiliation":[{"name":"Fellow ASME Systems Integration Division, Engineering Laboratory, National Institute of Standards and Technology, Gaithersburg, MD 20899 e-mail:"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"33","reference":[{"issue":"1","key":"2019100601534220400_B1","doi-asserted-by":"crossref","first-page":"3","DOI":"10.1177\/0954405412464012","article-title":"Reflections on the Role of Science in the Evolution of Dimensioning and Tolerancing Standards","volume":"227","year":"2013","journal-title":"Proc.
