Integrated Approach for Hybrid Shop Layout
(1993)
This thesis presents a comprehensive methodology for the design of a hybrid manufacturing shop layout that comprises both manufacturing cells and individual workcenters. The proposed approach targets the minimization of ...
Manufacturing Feature Instances: Which Ones to Recognize?
(1994)
Manufacturing features and feature-based representations have become an integral part of research on manufacturing systems, largely due to their ability to model correspondences between design information and manufacturing ...
Integrated Dynamic Simulation of Rapid Thermal Chemical Vapor Deposition of Polysilicon
(1997)
A physically-based dynamic simulator has been constructed to investigate the time-dependent behavior of equipment process, sensor, and control system for rapid thermal chemical vapor deposition (RTCVD) of polysilicon from ...
Polysilicon RTCVD Process Optimization for Environmentally- Conscious Manufacturing
(1996)
In the semiconductor manufacturing industry, optimization of advanced equipment and process designs must include both manufacturing metrics (such as cycle time, consumables cost, and product quality) and environmental ...
An Optical Area-Scattering Based Approach for the Measurement of Surface Roughness Formed During Machining
(1993)
The measurement of surface roughness during a machining process is critical for the automatic control of surface quality in a computer-integrated manufacturing (CIM) system. In this work, a method of surface roughness ...
Chemo-Mechanical Effects on the Efficiency of Machining Ceramics
(1992)
This paper presents an experimental study of the turning of a ceramic material - aluminum oxide (A12O3). Emphasis is given to gain a comprehensive understanding of the cutting mechanism. This study explores the utilization ...
A Mathematical Modeling of a Machining Operation System Using Finite Element Method
(1991)
A mathematical modeling of a Machining Operation Systems to evaluate stresses generated by the cutting force during machining, was modeled using finite element method. The geometric model was assembled using patran commands. ...
A Feature Based Approach to Automated Design of Multi-Piece Sacrificial Molds
(2000)
This report describes a feature-based approach to automated design of multi-piece sacrificial molds. We use multi-piece sacrificial molds to create complex 3D polymer/ceramic parts. Multi-piece molds refer to molds that ...
Selecting Flat End Mills for 2-1/2D Milling Operations
(2000)
The size of milling cutter significantly affects the machining time. Therefore, in order to perform milling operations efficiently, we need to select a set of milling cutters with optimal sizes. It is difficult for human ...
AI Planning Versus Manufacturing-Operation Planning: A Case Study
(1995)
Although AI planning techniques can potentially be useful in several manufacturing domains, this potential remains largely unrealized. In order to adapt AI planning techniques to manufacturing, it is important to develop ...
