The adoption of STEP-NC for the manufacture of asymmetric rotational Tcomponents

This paper reports ongoing research on the use of the evolving ISO 14649 standard, informally termed STEP-NC, which represents a new data model for the next generation of computer numerical controllers. The paper presents the major challenges in implementing STEPcompliant CAD\CAM (computer-aided design\manufacture) systems for manufacturing asymmetric rotational parts. It also discusses the need for a new ISO 14649 schema specific for asymmetric rotational parts and outlines a feasible solution to use the ISO 14649 data model for turn\mill machining.
