OMAC Consortium Converges on STEP-NC Standard at ARC Forum in Orlando, February 3rd, 2005.SEATTLE -- The Open Modular Architecture Control (OMAC OMAC Open Modular Architecture Control(ler) OMAC One-Key CBC Mac OMAC One Man Army Corps OMAC Observational Metahuman Activity Construct OMAC Ocala Municipal Arts Commission (Florida) )/STEP-NC consortium group will be demonstrating the early implementation of STEP-NC (Standard for Exchange of the Product Model data-Numerical Control) AP 238 specification for CNC (Computerized Numerical Control) See numerical control. CNC - Collaborative Networked Communication driven machine features. This demonstration will be held on Feb. 3rd, 2005 at the annual ARC Advisory Group Forum at Rosen Centre Hotel in Orlando as a part of the OMAC presentation tracks. The purpose of the demo will be to conduct an "Art to Part" scenario that involves the fabrication fabrication (fab´rikā´sh  n),n the construction or making of a restoration. of a machine part from design concept (CAD) through tool path definition (CAM) to CNC and machine tool solely based on the STEP-NC AP 203 & 238 specifications. The demonstration will illustrate the use of four different CAD/CAM CAD/CAM in full computer-aided design/computer-aided manufacturing. Integration of design and manufacturing into a system under direct control of digital computers. systems generating STEP AP 238 NC tool path process plans for test part milling. The STEP-NC Conformance con·for·mance n. Conformity. Noun 1. conformance - correspondence in form or appearance conformity agreement, correspondence - compatibility of observations; "there was no agreement between theory and Class 1 (CC1) test will be conducted that consists of the NAS-979 part (Circle -Diamond-Square Test) for 3-axis and 5-axis versions. The target CNC systems will include GE-FANUC 18i & 30i, and Siemens 840D simulators. (http://www.isd.mel.nist.gov/projects/stepnc/pilot-scenario.pdf) This test will demonstrate the significant potential benefits of STEP-NC AP 238 compliant CAD/CAM and CNC/machine tools systems. These benefits would include: --Interoperability of machine control data across CNC platforms --Enable a product lifecycle Product lifecycle or product life cycle is the course of a product's sales and profits over time. The five stages of each product lifecycle are product development, introduction, growth, maturity and decline. integration from design (CAD) through manufacturing processes (CAM) to CNC and the machine tool --Significantly increase the overall accuracy of machine part fabrication --Close the loop from the machine tool fabrication back to manufacturing process and product design. The goals of the OMAC STEP-NC Working Group are to promote the adoption of STEP-NC and foster the collaboration between the end users, CAD/CAM, CNC, and machine tool suppliers to accomplish this goal. The STEP-NC specification embodies the spirit of Lean Manufacturing Lean manufacturing is the production of goods using less of everything compared to mass production: less human effort, less manufacturing space, less investment in tools, and less engineering time to develop a new product. and will enable the application of Lean methods to the machine parts fabrication process. It is being implemented throughout the Manufacturing community from Aerospace to Automotive.

About the OMAC STEP-NC User Group The OMAC STEP-NC User Group is a working group within the Open Modular Architecture Controls User Group (OMAC) devoted to addressing the issues of interoperability The capability of two or more hardware devices or two or more software routines to work harmoniously together. For example, in an Ethernet network, display adapters, hubs, switches and routers from different vendors must conform to the Ethernet standard and interoperate with each other. in machine parts fabrication. They represent members of vertical industries and discrete manufacturing Fabricating products by assembling components and subsystems into larger systems. The automated assembly line is the prime example of discrete manufacturing such as in the making of automobiles, household appliances and computer systems. that include aerospace, automotive, heavy machinery, defense systems, and suppliers of CNC systems, CAD/CAM systems, and machine tools. Anyone interested in advancing machining technology and interoperability is encouraged to join the effort.
