Machinability Evaluation of Dental Restorative Materials
(1996)
Ceramic materials are ideal candidates for dental restorative applications for their color, texture, and mechanical properties which closely resemble those of the human enamel. However, due to the inherent brittleness of ...
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 ...
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 ...
Built-In Self-Test and Fault Diagnosis for Analog Circuits in the Frequency Domain
(1995)
Due to the increasing complexity of analog circuits, finding out whether an analog circuit meets the required specification is a difficult and time consuming task. We propose a complete Build- In Self-Test and Fault-Diangosis ...
Development of a Prototype System for On-Line Monitoring of Surface Roughness Using Fractal Geometry
(1994)
On-line measurement of surface roughness is an important element in a Computer Integrated Manufacturing (CIM) environment. Current methods of contact measurement are not suitable as they interfere with the machining process. ...
Control of Machining Induces Edge Chipping on Glass Ceramics
(1996)
Edge chipping is a phenomenon commonly observed during the machining of ceramic material. Characterization of edge chipping, both in macro and in micro scale, and correlating its formation to machining parameters form a ...
Locators and Sensors for Automated Coordinate Checking Fixtures
(1997)
This article proposes a systematic method for the optimal design of sensor locations for an automated Coordinate Checking Fixture (CCF). The fixture can be employed for making at-machine assessments of the dimensional ...
Microstructural Effects on the Machining Performance of Dental Ceramics
(1997)
Constraints of mechanical, thermal, and chemical properties are making ceramics the material choice for industrial and dental applications. The quality of a machined surface of ceramics is fundamentally dependent on the ...
Assessment of Non-Linear Dynamics of Material Removal on Surface Integrity
(1997)
In this chapter, we present our research on the study of non- linear dynamics observed during the machining of ceramic materials. We will focus on both innovation in machining technology and development of non-destructive ...
A Test Method for the Assessment of Tribological Aspects of Abrasive Machining
(1996)
Abrasive machining such as grinding involves simultaneous contacts, between the workpiece and several abrasive grits. Hence, it is difficult to assess the tribological effects (i.e., friction and wear) of individual grits ...
