Development of a high-speed high-precision micro-groove cutting process
A high-speed, high-precision chip formation-based micro-groove cutting process has been developed for cutting grooves in metals with nearly arbitrarily shaped cross-sections, which have widths and depths of a few hundred nanometers to a few microns, and lengths of tens of millimeters. A flexible …

A finite element study of the mechanics of micro-groove machining of 4340 steel
Microgroove features have been widely used in hot embossing molds, micro-heat exchangers, optical lithography masks, micro-forming dies, engineered surface textures, etc. The challenge of achieving such feature is the control of the process parameters to minimize the side burr that often damages …

Effect of micro-fin geometry on flow and heat transfer during evaporation in round tubes
… mechanism of heat transfer enhancement due to micro-fin geometry, this dissertation develops a novel approach to visualize the two-phase flow pattern in transparent micro-finned tubes under both adiabatic and diabatic conditions. Rather than the conventional sight-glass method (without internal …
