Evaluating Sheet Metal Nesting Decisions
(1998)
This paper describes models that estimate the cost and time of sheet metal punching when nesting (batching) orders. These models help decision-makers plan production and evaluate the impact of changing the nesting policy. ...
Fixture-Based Design Similarity Measures for Variant Fixture Planning
(1999)
One of the important activities in process planning is the design of fixtures to position, locate and secure the workpiece during operations such as machining, assembly and inspection. The proposed approach for variant ...
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 ...
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 ...
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 ...
Fractal Geometry Applied to On-line Monitoring of Surface Finish
(1994)
Surface finish of machined parts determines the functionality of the product and also the machining requirements for making the parts. On-line monitoring of surface finish has been an active area of machining research. ...
Integrated Product and Process Design Environment Tool for Manufacturing T/R Modules
(1997)
We present a decision making assistant tool for integrated product and process design environment for manufacturing applications. Specifically, we target microwave modules which use Electro-mechanical components and require ...
Integrated Manufacturing Facility Design
(1995)
This dissertation addresses for the first time the integrated problem of designing the manufacturing shop layout concurrently with its material handling system. Specifically, this study provides a method to derive shop ...
Control System Design for Active Vibration Control of a Turning Process Using PMN Actuators
(1996)
In recent years, intensive research has been conducted concerning the use of smart materials for active vibration control and also vibration attenuation for machine tools. This research merges the two research topics and ...
