Manufacturing WorkGroup

What Drives Your Manufacturing Performance? Actionable Intelligence. Real-Time Adjustment. Predictable Outcomes.

The OMAC Manufacturing Workgroup (OMW) is charged with maximizing the business value of discrete part machinery by providing automation guidelines, developing best practices, and assisting in international standards development.

Members of OMAC’s Manufacturing Workgroup are driving efforts to bridge the gap between digital technology and manufacturing. Our members include manufacturing leaders, automation firms, CNC and OEM machine builders, control technology providers, CAD/CAM suppliers, and end users around the world.

‍We conduct test trials and demos of digital twin manufacturing and leading edge manufacturing technology. We share knowledge and create guidelines and best practices. We develop tools and resources that help your company move into the future of digital manufacturing.
‍
Our primary objective is to create an environment that maximizes the machine automation choices of end-users and OEMs and increases their flexibility through greater openness and interoperability. To ensure that this goal becomes a “win-win” situation, we work with CNC controller vendors, CAD/CAM suppliers, and CNC OEMs to encourage their support of OMW “Connect and Manufacture” standards and best practices.

Digital Twin Manufacturing

Digital Twin Manufacturing drives business and manufacturing outcomes through actionable intelligence gathered throughout the production lifecycle. It continuously provides real-time analytical data based on a virtual representation of a process. OMAC and its members have been heavily involved in the development of frameworks for Digital Twin Manufacturing. A key accomplishment has been the development of the ISO 23247 series Automation systems and integration — Digital twin framework for manufacturing.

Parts 1-4 are published:

ISO 23247-1: 2021 Part 1: Overview and General Principals

ISO 23247-2: 2021 Part 2: Reference Architecture

ISO 23247-3:2021 Part 3: Digital representation of manufacturing elements

ISO 23247-4:2021 Part 4: Information exchange
‍

Parts 5 and 6 are in work:

ISO 23247-5 Part 5: Digital thread for digital twin

ISO 23247-6 Part 6: Digital twin composition
‍

While multiple use cases are contained in ISO 23247-4, Technical Reports are being developed, including:

ISO 23247-100 Part 100: Use case on management of semiconductor ingot growth process
‍

StepNC Collaboration

OMAC members work with other industry leaders on STEPNC (ISO 10303-238) standards and resources to improve portability and flexibility of machining data from CAD/CAM systems.

Edition 3 of STEP NC was published in 2022:

ISO 10303-238:2022

OMAC Standardized Subprograms

During the development of STEP NC, OMAC discovered a need for the development of standardized subprograms/macros resident locally at the CNC to allow consistent access to modal functionality as well as standard representations of STEP NC states. Some of these subprograms are in production at a major aerospace manufacturer and others are in development.
