Book excerpt: In the second part, a comprehensive dynamic surface generation model with consideration of the spindle dynamics, cutting mechanism and machining error is proposed. Firstly, an algorithm for the cutting force calculation and surface generation is developed. This algorithm takes into account the effect of minimum chip thickness and elastic recovery. A groove cutting experiment was conducted to verify the effectiveness of the algorithm. The experimental results indicate that the algorithm is capable of addressing the minimum chip thickness and elastic recovery in the micro cutting process. This algorithm is integrated into the comprehensive dynamic surface generation model. The simulated and measured surface topographies indicate that the low frequency enveloping phenomenon due to double frequency vibration of the spindle has a significant effect on the surface topography. The surface topography in cylindrical turning changes with different spindle speeds, even though the feed rate per revolution remains unchanged. In ultra-precision machining, the requirement of ultra-high machining accuracy and ultra-smooth surface roughness makes the effects of spindle errors on form accuracy and surface finish of machined components highly significant, even though the spindle errors can be down to the nanometric range. Thus, it is very significant for this research to investigate the effect of spindle errors on machining accuracy and surface roughness with experimental and theoretical methods. Based on the investigation, the spindle unbalance induced eccentricity, double frequency vibration, as well as the position drift of the AAL of the ABS have been identified. The development of the comprehensive dynamic surface generation model with consideration of spindle dynamics, effect of tool edge radius and machining error can enable optimization of the cutting conditions in ultra-precision diamond turning.

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.

This book was released on 2009 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The ultraprecision Single Point Diamond Turning (SPDT) technology has been developed for over 40 years and has been successfully applied to numerous fields. At present, the ultraprecision single point diamond turning technology already expanded to Single Point Diamond Machining (SPDM) technology, which includes several related processes in addition to the more conventional single point diamond turning. The other related processes are Fast Tool Servo (FTS), Slow Tool Servo (STS), broaching, and fly cutting. Though this technology has many notable merits, for example it can achieve micro meter or even sub micron form accuracy and nano meter surface roughness, there still has some drawbacks. One of the objectives of this research is to investigate one of these drawbacks, the diffraction and scattering of the ultraprecision single point diamond machined surfaces. Another objective is to extend the application of the SPDM by developing new design and new machining processes for freeform micro devices used in optical, mechanical, electronic, and biomedical fields. The mechanism and model of the ultraprecision single point diamond turning and micro cutting were first reviewed and discussed. The related subjects to the SPDT and micro cutting were also involved. The optical effects of diamond machined surfaces were studied. The diffraction and scattering generated from the diamond machined surfaces was analytically and experimentally studied. The influences from machining parameters, such as tool mark spacing, feedrate, spindle speed, tool radius, tool condition and different diamond machining process were considered. An empirical relationship between the machining conditions and the first order diffraction from the diamond machined surfaces was setup. This model can be used to select optimal machining conditions for diamond machining process. The design, machining and testing of microlens arrays by using SPDM process were introduced. Two microlens array examples were given. One is a 5 by 5 matrix arranged concave microlens array on flat brass substrate. The other one is a circular arranged 3D microlens array, which has 341 plano-convex micro lenslets, on a thin spherical PMMA substrate. Using the fabricated 3D microlens array, a 3D micro projection system was developed. The formed micro pattern dimension was 340 um by 460 um, giving an overall projection ratio of 34:1. It has been demonstrated that a low cost and simple manufacturing process for true 3D micro scale structures on non-planar substrates based on microlenses can be realized. Last but not least, an affordable polymer SAR micromixer was developed based on a high accuracy, low cost, and flexible micro machining process. Specifically both the mixing performance and the fabrication process were carefully studied. An improved design of the SAR micromixer was also given, the mixing efficiency of the two designs were 0.11 and 0.065 respectively.
