Laser micromachining has great potential as a MEMS (micro-electro-mechanical systems) fabrication technique because of its materials flexibility and 3D capabilities. The machining of deep polymer structures with complex, well-defined surface profiles is particularly relevant to microfluidics and micro-optics, and in this paper we review recent work on the use of projection ablation methods to f...

The use of diamonds to generate precision patterns and precision surfaces on a micrometer or nanometer scale has a history that dates back centuries. Uses of diamond in semi-automated machinery can be traced to ruling machines, pantographs, and ornamental turning with “diamond turning” dating back about a century. Poor behavior in machining more common materials (e.g. ferrous alloys) has limite...

K. Żak, W. Grzesik, M. Prażmowski, Opole University of Technology, Department of Manufacturing Engineering and Automation, Opole, Poland This paper presents a sequential machining process which incorporates CBN hard turning with cryogenic pre-cooling of the workpiece (CHT) and ball burnishing (BB). The main goal of this study was to select machining conditions enhancing the quality of parts mac...

Nowadays, micro-machining techniques are commonly used in several industrial fields, such as automotive, aerospace and medical. Different technologies available, the choice must be made considering many factors, type of machining, number lots required accuracy specifications terms geometrical tolerances surface finish. Lasers electric discharge machining (EDM) widely to produce micro-components...

Wireless signals are inherently generated during the spark discharges of micro-electro-discharge machining (μEDM). This work harnesses signals between 300-750 MHz for the monitoring of batch mode machining quality. In particular, the wireless spectra are used to sense incipient, debris-dominated machining that can be destructive to both the tool and the workpiece. Planar stainless steel (316L) ...

A new strategy with bone tissue engineering by mesenchymal stem cell transplantation on titanium implant has been dawn attention. The surface scaffold properties of titanium surface play an important role in bone regenerative potential of cells. The surface topography and chemistry are postulated to be two major factors increasing the scaffold properties of titanium implants. This study aimed t...

Laser milling provides a new method of producing components for the micro tool manufacturing industry. This paper considers the technical capabilities of laser milling when applied to the machining of components for micro tooling. Characteristics important for laser milling as a micro tooling manufacturing process are reviewed. These characteristics are surface finish, aspect ratio, dimensional...
