STEP-NC Based Manufacturability Evaluation

2010
This paper presents an evaluation method for part manufacturability. The data model used is the STEP-NC data model, i.e. ISO 14649. Firstly, the evaluation indices such as workpiece clamping, performance of machine tools, resources of cutting tools and auxiliary performances are presented.

Feature-based process planning using step-NC

International Technology and Innovation Conference 2006 (ITIC 2006), 2006
To survive in the global market, companies must integrate CAD, CAM and CNC so as to make products of higher quality with lower cost and shorter lead times. Traditionally, NC programming for machine tools is normally done by using G-code (ISO 6983 Numerical control of machines - Program format and definition of address words - Part 1: Data format for ...

Improving Shipyard Manufacturing Processes Using STEP-NC

Journal of Ship Production, 2005
A recent study showed that a UK Navy depot can save $4 million by rapidly manufacturing machined parts from a feature-based product data description. However, the study also showed that only 2,000 of a potential 13,000 parts can be eliminated from the inventory if the data are given just a feature-based description because there is a limit to the ...

STEP-NC Based Industrial Robot CAM System

IFAC Proceedings Volumes, 2009
Abstract In this paper a computer aided manufacturing (CAM) system for industrial robot machining operations is introduced. The system is based on the new machining standard STEP-NC which is rapidly making its way into the world of numerical controlled (NC-) machines (e.g. milling and turning machines).

Development of STEP-NC for intelligent machining

2017 International Conference on Advances in Mechanical, Industrial, Automation and Management Systems (AMIAMS), 2017
G-M codes have been used since decades and now have become obstacle in intelligent manufacturing. G-M codes only gives motion to the tool across the workpiece. It does not provide high level information of operation and feature to the machinist, who is completely unaware of operability of these codes.

Validating Portability of STEP-NC Tool Center Programming

Volume 3: 25th Computers and Information in Engineering Conference, Parts A and B, 2005
A joint effort between Boeing and the National Institute of Standards and Technology (NIST) was undertaken for validating and evaluating STEP AP238 (STEP-NC) Conformance Class 1 (CC1) for 5-axis machining. STEP-NC is a new manufacturing standard to support “design anywhere, build anywhere, and support anywhere.” The joint Boeing/NIST validation ...

Development of STEP-NC Based Manufacturability Evaluation System

Advanced Materials Research, 2012
A method and prototype system have been developed to assess manufacturability of a machining job with a known machine tool. The data for describing the machining task confirms to STEP-NC data model, i.e. ISO 14649. A group of manufacturability indices have been suggested used in the system.

Achieving a STEP-NC Enabled Advanced NC Programming Environment

2009
Modern manufacturing requires a flexible numerical chain of industrial products, in particular the relationships between CAD/CAM solutions and CNC. On longer can CNC controllers restrain their tasks at the execution of inflexible orders and choices made at earlier stages of the numerical chain.
