Development of a feature-based open soft-CNC system

Abstract

Modern Computer Numerical Control (CNC) is intended to be more flexible, interoperable, adoptable, open and intelligent. In realisation of such a CNC system, an ISO standard known as STEP for Numeric Control (STEP-NC) or ISO 14649 was developed in 2004 to alleviate a number of challenges associated with the widely used CNC standard (ISO 6983). Implementation of STEP-NC was initially carried out on some commercial CNC systems via an indirect STEP-NC programming approach. However, this approach failed to meet all the requirements of a modern CNC system, due to the translation of data from the high level to low level, which is vendor-specific and machine tool dependent, thus detrimental to the basic resource independent philosophy of STEP-NC. This paper presents a new generation of CNC systems, based on the Open Architecture Control (OAC) technology supported by STEP-NC data model to fundamentally solve these challenges. The developed system employs a new set of techniques for STEP-NC data interpretation, graphical verification, execution, monitoring and report generation that supersede the exiting techniques in scope and ca-DRB-

The Importance of STEP-NC in the IR 4.0 Manufacturing Systems

“…Manufacturing is one of the critical divisions of IR 4.0 that is expected to be intelligent, adaptable, open, flexible and interoperable [6]. At present, most of the manufacturing industries are using NC and CNC technologies, which are based on the five decades old data interface model, commonly known as G-Code (ISO6983).…”

A Case Study- Monitoring and Inspection Based on IoT for STEP-NC Data Model

“…STEP-NC called Standard for the Exchange of Product model data compliant with Numerical Control guarantees to resolve G-code drawbacks and enable integration from design to manufacturing without data losses as it is compliant with STEP [4]. Some previous study that had been implemented for open CNC system and open CNC control respectively are [5][6][7][8][9][10][11][12].…”
