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...

Micro-milling has found extensive applications in machining components with thin-walled microstructures, such as terahertz slow-wave structures, microfluidic chips, and micro-molds. Due to the influence of size effects, micro-milling exhibits higher specific energy consumption compared traditional milling, implying that more is consumed remove a unit volume material, particularly challenging-to...

Abstract High flexibility of the micro-milling process compared to nontraditional methods has led its growing application in manufacturing complex micro-parts with tight tolerances and high accuracies. However, difficulties such as tool deflection, size effect, wear limit micro-milling. In this regard, role laser-assisted machining (LAM) is highlighted prevent mentioned issues through reduction...

SKD11 is widely used in manufacturing die. With the development of industrial level, size die further reduced, and difficult processing problem high aspect ratio (HAR) micro-structures exposed. Micro-milling a suitable method for machining HAR micro-structures; however, inevitable generation burrs deteriorates machined surface. Previous studies have mostly focused on burr formation process shal...

In recent years, advanced materials with unique metallurgical properties such as super alloys, composites and ceramics have been developed to meet the demands of extreme applications. While these materials are harder, tougher, less heat sensitive and more resistant to corrosion and fatigue, they are also difficult to machine. Advanced materials are being widely used these days not only in the a...

In waterjet and laser milling, material is removed from a solid surface in a succession of layers to create a new shape, in a depth-controlled manner. The inverse problem consists of defining the control parameters, in particular, the two-dimensional beam path, to arrive at a prescribed freeform surface. Waterjet milling (WJM) and pulsed laser ablation (PLA) are studied in this paper, since a g...

Cutting forces prediction is very important for cutting tool’s design and process planning. This paper presents a fuzzy cutting force modelling method using subtractive clustering for learning evaluation. In this method, subtractive clustering, combined with the least-square algorithm, identifies the fuzzy prediction model directly from the information obtained from the sensors. In the micro-mi...

This paper presents the design of a precision electro discharge micro milling machine being designed and built in the Precision Systems Laboratory at the University of Kentucky. This machine will use micro electrodes to mill complex 3D cavities with electrical discharges between an electrode tool (cathode) and a workpiece (anode) submerged in dielectric fluid. The machine entails three axes of ...
