“…The product descriptions are based on internationally accepted standards, such as ISO, DIN, ANSI, etc. The technologies that are used in the reasoning process, such as the automated feature recognition of machine parts [8,9] and scheduling [10,11], are adopted from computer aided design (CAD) and operational research. The default automation of the entire search system provides to the production management ability of real-time decision making and with that increased flexibility.…”

Production Resource Search Using the Viral Phenomenon: Concept Introduction

et al. 2014

A significant challenge in a distributed production organisation is finding suitable production resources. In this study, we develop the concept of a production resource search system that can be used to organise a distributed manufacturing system in a global environment. The system is based on internet technologies and autonomous work systems, which are the building blocks of a dynamically orga nised production system. These building blocks encapsulate functionalities and competencies of management and manufacturing operations and an autonomous information system that supports autonomous decision-making and cooperation within the network. The developed search system thus focuses on finding suitable autonomous work systems. The internet viral phenomenon is used to automatically extend the search domain and exploit internet real-time capabilities. Thus, the search domain is not limited by a searcher's knowledge about it. An offer for the production of a product is directly sent to only a few potential work systems, which automatically pass it to related work systems. Thus, the offer is distributed rapidly and effortlessly throughout the network. Work systems benefit from such a system by always being informed about all the offers. The individual work systems automatically match the offer to their capabilities and respond with a bid to the production initiator (the searcher). The production initiator obtains real-time information about the state of the production world relative to the proposed product. The production initiator uses this information to make a rational decision about which resources to use.

In the context of advanced manufacturing, new models inspired by Internet technologies are being developed. The cloud manufacturing model strives to offer a similar experience for seekers of manufacturing services as cloud computing does for the users of the web: manufacturing clouds intend to offer manufacturing resources as services, much like processing power and storage space are available as services in cloud computing. The resulting business situation is favourable for both the service providers and the service end-users, especially in a highly dynamic manufacturing environment. Existing cloud manufacturing models operate in a centralised way through a cloud manufacturing platform, the management of which is identified as a critical part of the manufacturing cloud operation. In the article, a decentralised network architecture for cloud manufacturing is proposed. The architecture builds upon the concept of autonomous work systems for use as service providers. The operation of the system based on the architecture is described, wherein special attention is given to the communication within the emerged networks of service providers. Technical feasibility of the approach is also demonstrated. It is expected that the decentralised approach will enable a more flexible and scalable manufacturing cloud, which will have the ability to actively co-evolve with its environment.

In this paper we present toolpath generator which can produce steps of manufacturing along with the toolpaths for any 3D volumetric model. To achieve this automation, we propose sequence generation algorithm that generates sequence of setup orientations required to machine the design. The algorithm treats sequence generation as a search problem and finds shortest sequence of orientations using beam search strategy. Secondly, we suggest an operation planning algorithm that produces near optimal sequence of operations that minimizes no-cut time. Finally, we use this sequence of operations to generate G-code using zig-zag toolpath generation strategy. We tested the toolpath generated by our system against the toolpaths generated by expert CNC machinist using open source CAM softwares for 10 case studies.We found that sequence of orientations and operations generated by our system to be exactly same as the one's performed by machinist.
