Analysis of Surface Quality in Machining of Metals and Advanced Ceramics
(1992)
Of all the processes used to shape metals, it is machining in which the conditions of operation are most varied. Good dimensional accuracy and surface quality from machining processes should be maintained such that the ...
Assessment of Surface Integrity of Machined Ceramics Using Image Processing
(1995)
Recent manufacturing advancements have allowed designers to create ceramic materials with tightly controlled microstructures and compositions. Some advantageous properties of these materials are their light weight, high ...
Teaching New Product Development through a Product Engineering Approach
(1997)
This paper describes experiences gained in teaching a new course aimed at providing junior-level undergraduate engineering students with some of the fundamentals needed in developing new products. A six-stage engineering ...
Automated Generation of Group Technology Codes from a PDES Product Information Model
(1992)
The design and implementation of an automated system that generates group technology (GT) codes for microwave modules (MWM) is presented. An established GT coding scheme (MICLASS) was employed to capture the mechanical ...
Investigation of the Thrust and Torque Generated during Drilling Processes
(1992)
This thesis presents a study of the thrust and torque generated during drilling processes, with emphasis on applications to perform on-line monitoring of drilling processes. Two mathematical models are developed for ...
Real-Time Growth Rate Metrology for a Tungsten CVD Process by Acoustic Sensing
(2000)
An acoustic sensor, the Leybold Inficon ComposerTM, was implemented downstream to a production-scale tungsten chemical vapor deposition (CVD) cluster tool for in-situ process sensing. Process gases were sampled at the ...
Generation of Feature-Based Models
(1994)
Often there can be a number of ways to perform machining operations on a stock to produce a part, and only some of them are cost- and quality-effective. To determine the best machining sequence, it is necessary that each ...
Complexity of Production Management in a Petri Net Environment
(1994)
The objective of this paper is to show that Petri nets facilitate a comprehensive approach to production management and reduce the complexity of the problems involved at the expense of some constraints imposed on the ...
Class: Computerized LAyout Solutions Using Simulated Annealing
(1990)
A new method (Computerized LAyout Solutions using Simulated annealing - CLASS) that considers the inter-cell and intra-cell layout problems in a cellular manufacturing environment is presented. It addresses the relative ...
Using Neural Networks to Generate Design Similarity Measures
(1999)
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 ...
