CNC System Open

- Jul 18, 2018 -

Today's machine tools are moving in a flexible, versatile, and networked manner, and controllers must keep pace with this development. This requires the controller to be reconfigured, modified, expanded, and modified, and sometimes even requires the controller to be regenerated. An effective way to accomplish this task is to “open up”.

The requirement of “opening” of CNC system comes from the development of production methods. The requirements for additional technology from users and machine tool factories also come from the need of controllers to pursue high quality, low cost and improve product competitiveness. It can be said that "opening" has become an irreversible development trend of manufacturing equipment represented by CNC machine tools.

Europe, the United States, and Japan are currently conducting research on open architecture in the field of automation, and have introduced their own open architecture specifications. The trend of openness has become a trend in global manufacturing. In order to enhance the long-term development capability of its manufacturing industry and its competitiveness in the international market, the US government carried out research on the next-generation numerical control system NGC in the early 1990s. In 1989-1994, Martin was commissioned by the Ministry of National Defense. The NGC program, researched by Marietta Astronautics, has received wide attention as a proposal with an open structure. At present, the three major automotive industry giants in the United States: GM, Ford, and Chysler are working with controller vendors to develop a PC-based open modular controller named OMAC (Open Modular Architecture Control). In October 1991, an Open System Architecture for Control Swithin Automation System (OSACA) was launched in ESPRITIII with the goal of developing an open control system architecture in an automation system. The participating units are from 11 machine tool factories, controller manufacturers and universities in Europe. The project period is from May 1992 to May 1996, with an investment of 89 person-years and a total investment of 11.4 million European currency units. In December 1994, Japan established the NC Open Policy Committee under the IROFA (International Robotics and Factory Automation Technology Center), a peripheral organization of the Ministry of International Trade and Industry. A total of 11 companies participated in the NC Open Policy Committee. The main topics are “Definition of Open NC Devices” and “Production of Reference Models (including Interfaces)”. In 1994, the OSE Research Society was established in Japan. The initiators were: Toshiba Machine, Toyota Machine, Chapter 1 Introduction, Yamazaki, Japan IBM, Mitsubishi Electric and SML. The purpose of OSE's research is to develop an architecture and installation protocol for an open controller (a computer network-centric information processing technology and a high-value-added function driven by a general-purpose processor). Experimental validation and standardized activities.

The trend of openness has become an irreversible trend in global manufacturing. The result of this international trend will be a CNC system that is highly modular, can be easily integrated on the network, can be easily developed for the second time, and is supported by a large number of third-party application software, which is cheaper and has a new concept.
