Development of STEP-NC based machining system for machining process information flow

To realize the STEP-NC based machining system, it is necessary to perform machining feature extraction, generating machine-specific information, and creating a relationship between STEP-NC entities. A process planning system of a STEP-NC information flow that starts with constructing a machining feature from a CAD model will be developed. In this paper, a further in depth study of the implementation and adaptation of STEP-NC in manufacturing is studied. This study will help to understand how the data from CAD/CAM can be converted into STEP-NC codes and the machining process will be based on the STEP-NC codes generated

Ideas, Artifacts, and Facilities: Information as a Common-Pool Resource

The goal of this paper is to summarize the lessons learned from a large body of international, interdisciplinary research on common-pool resources (CPRs) in the past 25 years and consider its usefulness in the analysis of scholarly information as a resource. We will suggest ways in which the study of the governance and management of common-pool resources can be applied to the analysis of information and \u27the intellectual public domain.\u27 The complexity of the issues is enormous for many reasons: the vast number of players, multiple conflicting interests, rapid changes of technology, the general lack of understanding of digital technologies, local versus global arenas, and a chronic lack of precision about the information resource at hand. We suggest, in the tradition of Hayek, that the combination of time and place analysis with general scientific knowledge is necessary for sufficient understanding of policy and action. In addition, the careful development of an unambiguous language and agreed-upon definitions is imperative. As one of the framing papers for the Conference on the Public Domain, we focus on the language, the methodology, and outcomes of research on common-pool resources in order to better understand how various types of property regimes affect the provision, production, distribution, appropriation, and consumption of scholarly information. Our analysis will suggest that collective action and new institutional design play as large a part in the shaping of scholarly information as do legal restrictions and market forces
