Poor surface finish on die and mould transfers the bad quality to processed parts. High roughness is an example of that normally reduced by manual polishing after conventional milling machining process. Therefore, in order avoid disadvantages disadvantage machining, a sequence two operations proposed. The main operation run followed Rotary Ultrasonic Machining Assisted Milling (RUMAM). However,...

The rotary pipeline processor is a new architecture for superscalar computing. It is based on a simple and regular pipeline structure which can support several ALUs for efficient dispatching of multiple instructions. Register values flow around a rotary pipeline, constrained by local data dependencies. During normal operation the control circuits are not on the critical path and performance is ...

This paper presents a novel control architecture system which is composed of a multi-objective cost function which Pareto optimises the programming of cutting parameters while adapting the milling process to new cutting conditions if new constraints appear. The paper combines a self-optimised module which looks for and finds Pareto optimal cutting parameters according to multi-objective purpose...

This project serves as a literature review on the transformation and synthesis of magnetite from hematite under hydrothermal conditions as well as with Pulsed Laser Deposition (PLD) and milling. Magnetite forms over a similar range of elevated temperatures regardless the method that is used to synthesize it, including nonheterogeneous, loosely controlled environments such as a ceramics kiln. Ba...

The purpose of this study was to investigate the effect of electropolishing on cyclic flexural fatigue and torsional strength of rotary nickel-titanium endodontic instruments. Electropolished and nonelectropolished ISO size 30 (0.04 taper) EndoWave (J Morita Corporation, Osaka, Japan), ProFile (Dentsply Maillefer, Ballaigues, Switzerland), and RaCe (FKG, La-Chaux De Fonds, Switzerland) instrume...

This clinical report introduces a method for safe retrieval of a broken implant abutment screw. A reverse-tapping rotary instrument has been introduced in the market and is widely used to retrieve broken screws; however, it is difficult to use the rotary instrument unless an access hole for engagement of the rotary instrument is positioned directly on the center of the top of the broken screw r...
