An ontology for integrated machining and inspection process planning focusing on resource capabilities

The search for and assignment of resources is extremely important for the efficient planning of any process in a distributed environment, such as the collaborative product integrated development process. These environments require a degree of semantic interoperability, which currently can only be provided by ontological models. However, the ontological proposals centred on Resources for Machining and nspection Process Planning have a limited reach, do not adopt a unified view of machining and inspection, and fail to express knowledge in the manner required by some of the planning tasks, as is the case with those concerned with resource assignment and plan validation. With the aim of providing a solution to these shortcomings the manufacturing and inspection resource capability (MIRC) ontology has been developed, as a specialist offshoot of the product and processes development resources capability ontology. This ontology considers resource capabilities to be a characteristic of the resource executing any activity present in an integrated process plan. Special attention is given to resource preparation activities, due to their influence on the quality of the final product. After describing the MIRC ontology, a case study demonstrates how the ontology supports the process planning for any level, approach or plan strategy.This work has been possible thanks to the funding received from the Spanish Ministry of Science and Education through the COAPP Research Project [reference DPI2007-66871-C02-01/02].Solano García, L.; Romero Subirón, F.; Rosado Castellano, P.

Ontological-based validation of selected technological resources in integrated machining and inspection process planning

[EN] Based on previous research carried out to characterise the capacities of the resources involved in the execution of process planning, in this paper a methodology is presented for validating the configurations of resources assigned to the activities of integrated machining and inspection process planning. The methodology utilises concepts from the MIRC ontology and has graphic support that makes it more user-friendly. It also places special emphasis on the preparation activities used in the configurations of the resources and has been conceived as an aid to help in the final steps of the development of the process plan.Solano García, L.; Rosado Castellano, P.; Romero Subirón, F.

Ontological model centered on resource capabilities for the inspection process planning

[EN] Planning of a manufacturing process is a knowledge-intensive task in which a lot of information/knowledge must be managed, especially to the most conceptual levels. One of these tasks that is realized at supervisor planning level, consists of the assignment and configuration of resources for each activity to execute. Decisions that must be based on the resource capabilities, which depend largely on resource configuration, so that they can ensure a good result. As it is well known, the ontological approaches have shown well positioned in these cases where knowledge management is needed, moreover, these approaches enable a shared conceptualization, which make it possible to implement process planning in a collaborative environment, particularly when they are accompanied by a methodology that facilitates their interpretation and use. In previous researches, a general ontology for modelling the resource capabilities involved in a process has been proposed. This ontology has been specialized in order to support the process planning task and a methodology supported on graphical representation for validating the configurations of resources assigned in a manufacturing process has been proposed. Based on these results, in this paper, an extended ontology for the inspection process planning is presented. This extension includes new types of activities (inspection activities) and new type of resources (inspection resources), and is centered on the dimensional and geometrical capabilities of the resources. Additionally, using the ontology semantics and the proposed methodology, an application for an inspection plan is developed. The inspection process planning case is focused on the preparation activities used for obtaining the configurations of the resources, since they largely determine the capabilities of the resulting resources. The application demonstrates the proficiency of the ontology to execute manufacturing planning and inspection planning in a dual form.Solano García, L.; Rosado Castellano, P.; Romero Subirón, F.
