plasma cvm Chemical vaporization Machining an ultra precision Machining technique using high pressure reactive plasma
Nanotechnology, 1993Co-Authors: Y Mori, Kazuya Yamamura, Kazuto Yamauchi, Kumayasu Yoshii, T Kataoka, K Endo, Kohji Inagaki, Hiroaki KakiuchiAbstract:Conventional Machining processes, such as turning, grinding, or lapping, are still applied for many materials including functional ones. But these processes give rise to deformed layers which means that the machined surfaces cannot perform original functions. In order to avoid this, plasma CVM has been developed. Plasma CVM is a Chemical Machining method utilizing radical reaction. In plasma CVM, high density radicals are generated in plasma under atmospheric pressure, so that the removal rate is very high (>or=200 mu m min-1 for Si) and is equivalent to mechanical Machining methods. In this paper, basic concepts and some applications of plasma CVM will be introduced.

International Progress in Precision Engineering#R##N#Proceedings of the 7th International Precision Engineering Seminar Kobe Japan May 1993, 1993Co-Authors: Y Mori, Kazuya Yamamura, Kazuto Yamauchi, Kumayasu Yoshii, T Kataoka, K Endo, Kohji Inagaki, Hiroaki KakiuchiAbstract:Conventional Machining processes, such as turning, grinding, or lapping are still applied for many materials including functional ones. But those processes are accompanied with deformed layer, so that machined surfaces can not perform original functions. In order to avoid such points, Plasma CVM has been developed. Plasma CVM is a Chemical Machining method utilizing radical reaction. In Plasma CVM, high density radicals are generated in the plasma under the atmospheric pressure, so that removal rate is very high(ex. > 200μm/min for Si), and it is equal to mechanical Machining methods. In this paper, basic concepts and some applications of Plasma CVM will be introduced.

New developments in the process control of the hybrid electro Chemical discharge Machining (ECDM) process
Journal of Materials Processing Technology, 2005Co-Authors: T.k.k.r. Mediliyegedara, A.k.m. De Silva, David K. Harrison, J.a. McgeoughAbstract:Abstract Electro Chemical discharge Machining (ECDM) is a hybrid non-conventional manufacturing process which combines the features of electro Chemical Machining (ECM) and electro discharge Machining (EDM). One of the major advantages of ECDM, over ECM or EDM, is that the combined metal removal mechanisms in ECDM, yields a much higher Machining rate. This paper presents new developments in process control for the hybrid electro Chemical discharge (ECDM) process. The design stages and the implementation issues of a personal computer (PC) based real time controller for the ECDM process is discussed. A system identification experiment was carried out to obtain the dynamics of the system and a process control algorithm was implemented in software form.

an intelligent pulse classification system for electro Chemical discharge Machining ecdm a preliminary study
Journal of Materials Processing Technology, 2004Co-Authors: T.k.k.r. Mediliyegedara, A.k.m. De Silva, David K. Harrison, J.a. McgeoughAbstract:Abstract Electro-Chemical discharge Machining (ECDM) is a hybrid process which combines features of electro-Chemical Machining (ECM) and electro-discharge Machining (EDM). In order to develop a control strategy for this complex process, a preliminary study of a pulse classification system was carried out. By observing the voltage and current waveforms, pulses were classified in to five groups. A feed-forward neural network was trained to classify pulses with various activation functions. Five different activation functions have been employed for comparison. The trained neural networks were simulated. A quantitative analysis was performed to evaluate the performance of pulse classification system.
