Investigation of laser milling process characteristics for micro tooling applications

Flank Milling Surface Design with the Least Square Approach

Typically flank milling is used to machine ruled surfaces. In this paper, a method of designing doubly curved NURBS surfaces for flank milling using the least squares method is given. In this method, grazing points generated by the Bedi et al. [4] tool positioning method are used as sample points. The user defines the degree and the number of control points along two parametric directions of th...

Laser milling for micro tooling

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...

Design of a Precision Electro Discharge Micro Milling Machine

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 ...

Development of Endmills for Milling Hardened Steel Molds and Copper Electrodes

In recent years, mold manufacturers have had to meet growing demand for high precision molds, low cost and short delivery time due to the miniaturization of finished products, price competition with overseas companies, and reduced model cycles. In line with these market changes, users have been gradually inclined to shift their machining methods applied to key mold parts (made of hardened steel...
