“…With NURBS interpolation, manufacturing tool paths are not only more accurate and lead to lighter program files [26], but also are carried out more smoothly on the machine tool because of their dynamic parameters are smoothly continuous. Machined surfaces using NURBS show very few cutting marks because feedrates are more stable than those with linear interpolation.…”

Abstract:The manufacturing area has benefited from various progresses over the last decades, such as High Speed Machining (HSM), but CNC programming is still based on dated practices and habits with a segmented unidirectional CAD/CAM/CNC data chain. Decision power is limited at the NC controller stage and online process optimization is difficult. In contrast, advanced programming approaches, such as STEP-NC [9], aim to unify the product/process data within a consistent environment from design to machining. Hence, openNC controller solutions which allow access to their internal algorithms, have emerged. It is consequently possible to implement new tool path control algorithms that respond directly to the actual machining condition. This paper focuses on the interest of openNC controllers to develop advanced programming approaches for HSM processes. The major drawbacks of legacy controllers in the implementation of advanced tool path generation methods are discussed and the most significant openNC projects are reviewed. An integrated test platform has been developed. The advanced HSM programming methods enabled by this openNC controller are discussed.

“…This type of CNC systems can run on universal PC hardware and utilizes various software resources, that makes the CNC reconfigurable, interoperable, portable and interchangeable [21]. Seen from the infrastructure of CNC, the current trend is towards developing PC-based open soft-CNC [22]. This paper presents a software system for open architecture CNC machine controller, which translate both data interfaces (ISO 14649 & 6983) codes as per internal structure of CNC machine.…”

CNC technology is the key technology of the machine tools, which are the base of industrial unit computerization. CNC machines are operated by controllers, each of which has a software module inside known as interpreter. The function of interpreter is to extract data from CAM system generated code and convert to controller motion commands. However, with the development of numerical control technology existing CNC systems are limited with the interpreter lacking in expansibility, modularity and openness. In order to overcome these problems open architecture control was introduced. In this paper, a conceptual module of new software system is presented. The developed system is able to interpret ISO 14649 and 6983 code and translate as per internal structure required by the CNC machine. It interprets position, feed rate, tool, spindle etc data and translates to CNC machine. At the mean time it is also able to generate output in text and XML files as per user defined file structure.

“…[12] States that "personal computer has been one of the preferred hardware platform for open CNC system because of its good openness and high performance price ratio". With the development of manufacturing world, [13] highlights that the current trend of CNC machines is towards the development of PC based Soft-CNC systems. OAC is a concept derived from the flexibility requirement based on computer integrated technology.…”

Abstract. The Computer Numerical Control (CNC) machines works on the technology that uses minicomputers to generate, parse and execute the sequential control. These machines were introduced in 1970's, this technology replaces the Numerical Control (NC) with the computers. The controller is the main part of the CNC machine that is composed of two parts: software and hardware. The software part of the controller is commonly known as interpreter that translates the International Standards Organization (ISO) data interface model instructions to the hardware part of the controller. Todays commercial CNC systems are operated by ISO 6983 data interface model that is proved to be a low level language and beside that these CNC systems are found to be closed in nature due to the dependency on vendors specification. Due to these shortcomings the current systems are fail to achieve the targets of future CNC system. In order to overcome these problems and limitations the new data interface model and Open Architecture Control (OAC) technology were introduceds. In this paper a new translator for the interpretation of ISO 14649-21 for OAC CNC systems has been presented. This module interprets the data from STEP-NC code and translates as per required structure of CNC machine. Developed module also enables the on machine modification facilities and provides a platform to generate physical output file in .txt and .xml formats as per user defined structure. The development of these kind of systems will makes CNC system more open, flexible, adoptable, interoperable, and intelligent.
