The international Standard for Product Model Data (STEP ISO 10303) completely defines

the information used by engineering and manufacturing activities throughout a product

life cycle. STEP standards development has extended their reach onto the shop floor by

attacking the CAM (Computer Aided Manufacturing) and CNC machining standards.

Specifically, STEP-NC, ISO 14649-11, is an extension to STEP that seeks to displace the

existing G code formats specified in by RS-274-D/DIN 66025 standards. Effectively,

STEP-NC makes the “post processor” on CAM systems obsolete. A single data format

for the CAD and the machine will coexist to enable information to flow from the ma-chine

tool to upstream design tools. STEP-NC is a feature-based language being tried

as a G code replacement. Basically, it retains the original design features of mechanical

components or fabricated metals in the executable instructions brought to the machine

tool on the manufacturing floor.

The STEP-NC specification coupled with XML promises to connect CNCs to the Internet

and streamline the NC machining process. Combining these technologies will offer ma-chine

tool geometry platform independence, better product model data exchange, and

new levels of manufacturing collaboration. An XML standard schema is being developed

for STEP-NC. This standard will insure that all data in a product model is tagged

in a manner consistent with the machining operations defined by the STEP-NC specifica-tion.

Essentially, XML provides a very convenient way to link manufacturing processes,

tool paths, and tool selection information with geometry, features, and machining steps

in the database. This will prove to be one of the emerging technologies that will enable

collaborative e-manufacturing to become a reality on the plant floor.

NC Process Planning

To fully take advantage of STEP-NC and the open NC Controller, AP 213 must be enhanced

To support both dimensional and geometric tolerances (if AP 213 is enhanced with AP 224 tolerances the validation activity can support inspection process ).

To support STEP-NC (current AP 213 spec references the traditional “M” and “G” code standard).

To support the 2nd edition STEP integrated resources (IR) and to harmonize with PDM.

harmonization of standards for manufacturing

Harmonization of Standardsfor Manufacturing

All manufacturing standards need to be consistent

and harmonize machining features, dimensional tolerances, and geometric tolerances for a successful exchange of product data throughout the manufacturing life cycle.

To ensure consistency, all manufacturing application protocols need to have the same product structure, the need to be harmonized with the PDM Schema.
