superior Surface integrity by sustainable dry hard milling and impact on fatigue
Cirp Annals-manufacturing Technology, 2013Co-Authors: W LiAbstract:Abstract Dry milling is a sustainable Finishing process in mold/die manufacturing. However, the progression of tool wear causes great concern on inferior Surface integrity and reduced part life. This study focuses on the relationships among process conditions, Surface integrity, and fatigue in dry milling of hardened H13 steel. Superior Surface integrity including Good Surface Finish, highly compressive residual stress, free-of white layer, and work-hardening can be produced up to flank wear at least 0.2 mm. Furthermore, fatigue life of the machined Surfaces in Finish conditions reaches over 1 million cycles under the synergistic effect of high compressive residual stress and work-hardening.

Micromachining of diamond substrates with waveguide excimer lasers
Lasers as Tools for Manufacturing, 1994Co-Authors: C. Paul ChristensenAbstract:Waveguide excimer lasers in combination with high-resolution imaging and precision motion control systems are capable of direct-write shaping of diamond and diamond-like materials. 3D structures can be produced by scanning the workSurface under the focused beam and varying the energy delivered to the workSurface through use of various exposure algorithms. Using this technique, we have produced microstructures in diamond that demonstrated high spatial resolution and Good Surface Finish.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.

Waveguide excimer laser fabrication of 3D microstructures
Laser-Assisted Fabrication of Thin Films and Microstructures, 1994Co-Authors: C. Paul ChristensenAbstract:Waveguide excimer lasers in combination with high-resolution imaging and precision motion control systems are capable of direct-write shaping of many polymers, ceramics, glasses, and metal films. Three-dimensional structures can be produced by scanning the workSurface under the focused beam and varying the energy delivered to the workSurface through use of various exposure algorithms. Using this technique, we have produced 3-D structures in polyimide and diamond that demonstrate high spatial resolution and Good Surface Finish.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.

An investigation on Surface Finish and flank wear in hard machining of solution treated and aged 18 % Ni maraging steel
Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2017Co-Authors: M. Santhanakumar, R. Adalarasan, S. Siddharth, A. VelayudhamAbstract:The hardened 18 % nickel maraging steels find potential application as an engine component for heavy vehicles and as armour metal in defence. The task lies in obtaining a Good Surface Finish and minimal tool wear in hard machining of this high-strength material in a solution annealed and aged condition. The present work reports the optimal machining condition to obtain a Good Surface Finish and lesser width of flank wear land during hard turning of maraging steel. The cutting speed, feed rate, and depth of cut are identified as the dominant parameters influencing the process responses. The working ranges of these machining parameters are set through the design of experiments, and an L_27 orthogonal array is used for conducting the machining trials in a CNC lathe using cubic boron nitride (CBN) cutting inserts. The Surface roughness is measured using a Surface profilometer, while the width of flank wear land is found out using a video measuring system. The grey-based response Surface methodology is used for analysis. A lower value of Surface roughness (0.434 µm Ra) and lesser flank wear (0.0234 VB_max, mm) is obtained at optimal machining condition (cutting speed 174.28 m/min, feed rate 0.01 mm/rev, and depth of cut 0.3549 mm). Atomic force microscopy (AFM) images and P-profile graphs of machined Surface are also examined. Furthermore, the temperature distribution is also simulated for the optimal machining condition using the DEFORM 3D software.
