Forum to host demo of new STEP
specification
The OMAC/STEP-NC consortium group will demonstrate the early implementation of the AP 238 specification for CNC driven machine features at the ARC Advisory Group Forum.
The Open Modular Architecture Control (OMAC)/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 driven machine features on 3rd February 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 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 and 238 specifications

Worldwide capital and operational expenditures for plants in the electric power industry, which totalled more than $374 billion in 2003, will exceed $453 billion by the end of 2008.
Natural gas boosts Coriolis flowmeter market
The worldwide market for Coriolis flowmeters is expected to grow at a CAGR of 8.9% over the next five years, according to a new study.
The demonstration will illustrate the use of four different CAD/CAM systems generating STEP AP 238 NC tool path process plans for test part milling.
The STEP-NC Conformance Class 1 (CC1) test will be conducted that consists of the NAS-979 part (circle -diamond-square test) for three- and five-axis versions.
The target CNC systems will include GE-Fanuc 18i and 30i, and Siemens 840D simulators.
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; enabling product lifecycle integration from design (CAD) through manufacturing processes (CAM) to CNC and the machine tool; significantly increasing the overall accuracy of machine part fabrication; and closing 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 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.
