Implementation of hierarchical design for manufacture rules in manufacturing processes
… of manufacturing processes is important. Design for Manufacture (DFM) is the practice of designing products with manufacturing issues using an intelligent system, which translates 3D solid models into manufacturable features. Many existing and potential applications, particularly in the …

Material evaluation and selection processes to enable design for manufacture
In order to optimize product designs it is necessary to quickly evaluate many candidate materials in terms of performance and processing costs. Evaluation using physical prototypes yields concrete results but is time intensive and costly when dealing with multiple optimization objectives. As an …

Application of design for manufacture principles to building design and construction.
… is to answer the two research questions: how can design for manufacture be applied during building component design and building design?; and how can the application of design for manufacture be successful in improving the productivity and quality of building component production and building …

Development of a manufacturing feature-based design system
… approach of the product development cycle: the design process is not integrated with other activities and thus it can not provide information for subsequent phases of product development. In order to eliminate this problem, many modern CAD systems allow the composition of designs from building …

2007 Formula SAE pedal box
The purpose of this thesis is the design and implementation of the pedal box for the 2007 MIT Formula SAE car. Formula SAE is a collegiate competition in which groups of degree seeking students design and manufacture small formula style race cars to compete on design, cost, marketing, and …

Improving the manufacturing yield of investment cast turbine blades through robust design
… casting foundries by aerospace companies that design and build jet engines. Aerospace companies have found that casting defects are an important cost driver in the price that they pay the foundries for the turbine blades. Defect types include porosity, stress, grain, fill, and mold-related …

Compliant Mechanism Suspensions
… Fatigue failure has been found to be a limiting design constraint which competes with space and weight constraints. Controlling wheel motion in response to control forces has also been shown to be an important functional requirement for a compliant suspension system. Vehicle applications that are …

Underactuated Exoskeletons for Lifting, Carrying, and Walking Assistance
… to practical reality in everyday life. Various designs have provided viable means for individuals to regain capabilities that were lost or perform tasks not previously possible by their ability alone. In this research, I propose two novel exoskeletons for walking assistance and heavy load …

An investigation into the detection and identification of buried metal objects
… measure the magnetic field. Analogue and digital design and signal processing techniques are employed to provide information relating to variation in the magnetic field. The implementation of a microcontroller and appropriate software is used to create a system able to detect and identify a buried …

Feature based costing of extruded parts
… model, which is intended to be used early in the design phase of a part, when the geometry and the material are being defined in a Computer Aided Design (CAD) software by the designer. The cost model was developed specifically for hot extruded parts made of aluminum alloys, extruded in the forward …

Developing an Integrated Design Support Framework to Enable Mass-Customisation in Multi-Storey Timber Building Projects
… sector, which possesses significant potential for MC. MC aims to provide choices for heterogeneous apartment demands in a prefabricated construction context. It intends to deliver marketable building products at a competitive cost close to mass-produced buildings. To maximise their benefits, …

Modular Manufacture and Construction of Small Nuclear Power Generation Systems
… and develops a new conceptual framework for modularising nuclear plants based on their size and subject to transport constraints. Transportation limits the type and amount of construction work that can be moved off-site. Due to their smaller size, up to 80% of a SMR plant can be …

Within-Die Delay Variation Measurement And Analysis For Emerging Technologies Using An Embedded Test Structure
… variability, and microscopic etch loading). Unfortunately, accurate models of within-die PVs are becoming more difficult to derive because of their increasingly sensitivity to design-context. Embedded test structures (ETS) continue to play an important role in the development of models of PVs …

The Turgo impulse turbine : a CFD based approach to the design improvement with experimental validation
… runners and injectors in timescales suitable for design optimisation studies and which correlate well with experimental results. This work has however focussed mainly on Pelton turbines and the use of CFD in the analysis and optimisation of Turgo turbines is still in its infancy, with no …
