This paper describes a neural network-based design similarity measure for a variant fixture planning approach. The goal is to retrieve, for a new product design, a useful fixture from a given set of existing designs and their fixtures. However, since calculating each fixture’s feasibility and then determining the necessary modifications for infeasible fixtures would require too much effort, the...

In this paper, we describe commonly used fixture setup strategies as well as their disadvantages and advantages. We propose a dependency model and a test fixture sharing model that allow the definition of a new fixture setup strategy. This strategy promotes code reuse by sharing fixture setups between test classes. The models are evaluated through a case study where the new fixture setup strate...

Test automation is one of the major areas in software engineering. Test automation can reduce the high cost of software development and at the same time increases the reliability of the testing process. In this paper we present a novel specification based framework for automating test process based on use case scenarios. It receives software specification that defined with UML at design level a...

Cost and product quality are significant attributes in manufacturing processes, such as multistation assembly. We use multiobjective optimization for integrated tolerance allocation and fixture layout design to address their interaction and to quantify tradeoffs among cost, product quality, and assembly process robustness. Design decisions relate to product tolerances, assembly process toleranc...

This paper describes a graphical tool referred to as StabTool, developed within a commercial software package, TELEGRIP. The basis of StabTool is that it allows functions that can determine the various types of stabilities of an arbitrarily shaped object held by a fixture, robotic gripper, or of a set of objects piled randomly together. Several modes of operation are possible: (1) stability tes...

Abstract In order to respond a shortened development time of today’s transmission systems, the automation certain steps in design process is essential for ensuring an efficient process. Computer-aided tools are widely used analyzing given configurations because standardized methods available evaluate load carrying capacity all key components simple gear train, namely bearings, shafts and gears....

Despite refinements in surgical technique, including bone grafting and sophisticated prosthetic reconstructions, there are limitations to what can be achieved with bone-anchored fixed prostheses in patients with advanced atrophy of the maxillae. A new approach was suggested by a long-term study on onlay bone grafting and simultaneous placement of a fixture based on a new design: the zygoma fixt...
