“…A properly conceived KBE application is stable, i.e., resilient to input errors and model inconsistencies and can be used by all experts involved in the design process (La Rocca, 2012). It is also worth underlying that several works are already available in the literature concerning the use of KBE systems to guide the design of manufacturing tools (e.g., see (Vosniakos and Giannakakis, 2013;Kakish et al, 2000)) and, specifically, of injection moulds (e.g., (Lou et al, 2004;Mok et al, 2008;Chan et al, 2003)). However, less examples exist concerning the automation of the design of thermoforming moulds (e.g., (van der Laan et al, 2004)).…”

In Mass Customisation (MC), products are intrinsically variable, because they aim at satisfying end-users' requests. Modular design and flexible manufacturing technologies are useful strategies to guarantee a wide product variability. However, in the eyewear field, the current strategies are not easily implementable, due to some eyewear peculiarities (e.g., the large variability of the frame geometry and material, and the necessity to use specific manufacturing phases). For example, acetate spectacle-frames are bent through a thermoforming process. This particular phase requires dedicated moulds, whose geometry strictly depends on the frame model to be bent; consequently, changes of the frame geometry continuously require new moulds, which have to be designed, manufactured, used, and finally stored. The purpose of this paper is to propose a new strategy to transform a dedicated tool (i.e., a thermoforming mould) into a reconfigurable one, to optimise the tool design, manufacturing and use. First, how the frame features influence the mould geometry has been investigated, creating a map of relations. On the basis of this map, the conventional monolithic-metallic mould was divided into "standard" (re-usable) and "special" (ad-hoc) modules, where the "special" ones are in charge of managing the variability of the product geometry. The mapped relations were formalised as mathematical equations and then, implemented into a Knowledge Based Engineering (KBE) system, to automatically design the "special" modules and guarantee the mould assemblability. This paper provides an original example of how a reconfigurable thermoforming mould can be conceived and how a KBE system can be used to this aim.

“…This type of model establishes a group of reference elements that provide a base on which the fixture designer can lean in order to define the configuration of the fixture. Kakish [8] has developed knowledge bases for fixture elements, defining the design parameters and specifications used in the fixture design. This approach has been developed by the need to represent complex models in a field of fixture design.…”

Nowadays, the inspection process is an essential part of the manufacturing process, where a product is subjected to verification of the geometric features, dimensions and tolerance specifications with respect to the product design specifications. One of the most interesting topics in the automation of the inspection process is the right fixture design. In the fixture design process we have used the information provided by the part design and manufacturing process. However, the lack of integration and structuring of this information results in one of the most important problems, producing an increase in the time and cost implied in the development of the fixture design and its implementation. For this reason, this work presents a knowledge model for the inspection fixture design process for a Coordinate Measuring Machine (CMM), which allows the automation of the inspection fixture design process to be made easier, reducing time and cost associated to the inspection process and to the manufacturing process in general.
