Download or read book Materials Characterisation and Mechanism of Micro Cutting in Ultra Precision Diamond Turning written by Sandy Suet To and published by Springer. This book was released on 2017-05-23 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an in-depth study and elucidation on the mechanisms of the micro-cutting process, with particular emphasis and a novel viewpoint on materials characterization and its influences on ultra-precision machining. Ultra-precision single point diamond turning is a key technology in the manufacture of mechanical, optical and opto-electronics components with a surface roughness of a few nanometers and form accuracy in the sub-micrometric range. In the context of subtractive manufacturing, ultra-precision diamond turning is based on the pillars of materials science, machine tools, modeling and simulation technologies, etc., making the study of such machining processes intrinsically interdisciplinary. However, in contrast to the substantial advances that have been achieved in machine design, laser metrology and control systems, relatively little research has been conducted on the material behavior and its effects on surface finish, such as the material anisotropy of crystalline materials. The feature of the significantly reduced depth of cut on the order of a few micrometers or less, which is much smaller than the average grain size of work-piece materials, unavoidably means that conventional metal cutting theories can only be of limited value in the investigation of the mechanisms at work in micro-cutting processes in ultra-precision diamond turning.

Download or read book Ultra precision Machining of Difficult to cut Materials with Geometric Error Compensation and Precise Tool Setting written by Sangjin Maeng (Ph.D) and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultra-precision machining technology has advanced recently but lacks understanding of process physics, processing technology, and peripheral technology. Research on ultra-precision machining of difficult-to-cut materials is hard to find, while demand for ultra-high precision dies and molds from those materials has increased due to their superior mechanical properties and thermal stability. Challenges in the machining of superhard materials are excessive tool wear and brittleness in cutting. Peripheral technologies are another major challenge since these are not up to the accuracy of the machine tool and thus, these became a significant bottleneck for the entire machining process. Therefore, the improvement of peripheral technologies is necessary to match the level of precision of ultra-precision machine tools, and the development of the machining technology for difficult-to-cut materials is required to achieve ductile machining with wear resistance. This study handles peripheral technologies - precise tool setting methods and geometric error compensation methods - and machining strategies - a patterned tool and a micro-grinding tool. The studies on peripheral technologies improve the form accuracy by enhancing the precision of the tool setting and correcting the geometric errors in machine tools. Engraving patterns on the rake face of an insert tool is one of the potential methods to reduce the friction coefficient between chip and tool and prolong tool life. Micro-grinding is an effective micromachining process to achieve the ductile machining and minimize tool wear. The research on micro-grinding provides the optimization of micro-grinding tool design and process conditions by understanding grinding forces. The integration of these studies leads to the improvement of the surface quality and the form accuracy in ultra-precision machining of difficult-to-cut materials with long tool life.
