Development of an expert system for cutting-off process selection.
… engineer is faced with many different processes and a wide variety of alternative combinations of parts and cutting-off tools. The problem is therefore to select the optional and most economical combinations of processes and parameters for cutting-off a given product. To assist in this …

A study on the cleaning and modification of metal surfaces by direct current cathodic electrolytic plasma process
The processes of surface treatments or surface modifications, more formally known as surface engineering, tailor the surfaces of engineering materials. The treatments are usually intended to change physical properties such as thermal or electrical conductivity, modify the surface dimensions, i.e. …

Identification of leading indicators for producibility risk in early-stage aerospace product development
… and schedule. Detailed product definition and process variation have traditionally been a focus area for understanding risk for producibility losses. It is proposed for this investigation that while assumptions inherent to product configuration and process selection can significantly impact …

Cost modeling and design for manufacturing guidelines for advanced composite fabrication
… during the early stages of the development process. Presently, many cost estimation methods are available to the public for metal processing, but there are almost none (excluding proprietary) for advanced composite materials. Therefore, the central objective of this thesis is to provide a …

Enhancing operational efficiency in hydrocarbon supply chains through engineering methods: a case study in fuel dispatch optimization
… deficiencies in machine maintenance, lack of process standardization, and congestion in dispatch areas, negatively impacting productivity and increasing operational costs. This situation highlighted the need to apply method engineering techniques to optimize processes and improve operational …

A true generative CAPP system for DFM application to machined components
… and the manufacturing system. Computer-Aided Process Planning (CAPP) is an essential key for achieving closer links among design and manufacturing activities. The purpose of process planning is to generate feasible sequences for producing a part in a given production facility. To generate …

Design optimization for the two-stage bivariate pattern recognition scheme
In manufacturing operations, unnatural process variation has become a major contributor to a poor quality product. Therefore, monitoring and diagnosis of variation is critical in quality control. Monitoring refers to the identification of process condition either it is running within in …

Variation propagation modelling and cost-oriented process optimisation for aircraft assembly
… and time consuming variation management processes such as shimming in order to ensure the final assembly is within specification. This thesis focuses on how the overall production cost can be minimised, and presents a methodology to relate part manufacture and assembly variation to the …

Ultrasonic Sealing of Aluminum Foil Based Laminate Food Packaging Materials
… seals with the highest peeling strength.The process selection is critical to minimize material damage in the seal zone by ultrasonic tool vibration. It was shown that aluminum was particularly sensitive to the sealing technique and anvil type because it was easily damaged. Successful seals …

Macro-CAPP: a CAPP CIM interface
There exists today a variety of Computer Aided Process Planning (CAPP) systems that have been designed, developed, and implemented irrespective of the facility's condition and status. It is often found in practice that Computer Integrated Manufacturing (CIM) constituents such as production control, …

Organic fouling of desalination membranes
… osmosis (RO) is the most ecient desalination process for almost any water source, but it is susceptible to membrane fouling, which can reduce product water quality and raise energy consumption. Fouling can be reduced through (energy-intensive) pretreatment, delayed by membrane coatings, and …
