“…These controllers would then be modified to suit the different end-users, thus promoting technical and commercial developments of industrial machines. Development for this architecture, focused on five levels [3] To aid in the execution of this architecture, the consortium developed the OSEC API based on an interface protocol that is used to exchange messages between controller software components. Each component represents functional and real-time blocks within the system that are interconnected through the API as shown in Figure 4.…”

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.

“…It is therefore not surprising that such controllers are designed and can be programmed according to a relatively rigid approach [7], which makes almost exclusive reference to machine tools and shows significant limitations when applied to other types of machines [8], including additive manufacturing systems.…”

Mechatronic Design for an Extrusion-Based Additive Manufacturing Machine

3D printers, especially in the implementation of innovative extrusion processes which do not have a long history of development, are often built by adapting mechanical designs, drives and controls previously developed for generic machine tools. This is done through a process of choice and integration which is based principally on empirical criteria and taking into account separately the different aspects and parameters. Hereafter, we present an integrated mechatronic approach which has been adopted to design from the scratch a machine to implement the innovative metal injection moulding (MIM) technology. Its extrusion rate involves the adaptation of the generated trajectories and consequently requires "ad hoc" designs, drives and numerical controls (NC) to enable non standard acceleration (and hence torque) setpoint curves. Overall, the project resulted in an acceptable workspace volume (depending on the number of degrees of freedom of the platform) and allows one to combine the extruder flow rate, the given accuracy and the required working speed (1 m/s). The system is currently used as a test bench for exploring and optimizing the parameter space of a new MIM process.

“…To overcome these problems open architecture control technology was introduced [16,18]. The aim of this technology is to develop controllers independent from the manufactures technology, which allows the user to buy hardware and software from several different manufactures and freely assemble the acquired piece of equipment [19,20]. 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].…”

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.
