  7. Abstract:
  8. In the domain of manufacturing, computer numerically controllers (CNC) technology is a major contributor to the production capacity of the enterprises. The advances in CNC technology coupled with enhancements in computing systems have provided the basis to re-examine the way in which computer-aided systems (CAx) can be used to enable global manufacturing. Interoperability of the various components of the CAx chain is therefore a major prerequisite for manufacturing enterprises for becoming strategically agile and consequently globally competitive. Being interoperable, resources can be utilized interchangeably in a plug-and-produce manner. Over the last 8years the eminence of a STEP standard for machining entitled STEP-NC (numerical control) has become a well-known vehicle for research to improve the level of information availability at the CNC machine tool. In this thesis, based on STEP-NC standard and CNC machines, a framework for conjugating process plans of several different or similar prismatic parts, in order to reduce total time of machining part, is provided.After interducing STEP-NC standard and reviewing literature related to this standard, the proposed framework is explained through two major phases. Enabling implementation of the model, a program is prepared and its validity is tested by means of a case study
