Micro-Machining of Sculptured Surfaces by Lathe-type Ultra-precision Milling Machine.

5-Axis Flank Milling of Sculptured Surfaces

This chapter covers the various free-form surface flank milling strategies available, focusing in particular on those for ruled surfaces as widely used in defining turbomachine parts. All these positionings seek to reduce interference between the cutting tool and the surface to be milled so as to respect the tolerances dictated by the Design Office. The range of strategies presented goes from t...

Profile Generation for Brittle Materials by Using Ultra-precision Lathe with On-machine Measurement System

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 ...

Ultra-precision Machining Systems; an Enabling Technology for Perfect Surfaces

The technology of ultra-precision machining, spanning almost three decades, has only in recent years experienced major advances in machine design and, subsequently, performance and productivity. In the 1970’s, ultra-precision machining techniques were successfully adopted for the manufacture of computer memory discs used in hard drives, and also photoreceptor components used in many photocopier...

Geometric Contribution to 3-axis Milling of Sculptured Surfaces

When we are trying to shape a surface X by 3-axis milling, we encounter a list of problems: First we have to decide if locally the milling tool Σ is able to move along the surface such that its envelope during the motion is the given surface. This is a question involving the curvatures of X and Σ. Second, we want to avoid that while milling in one part of X, Σ intersects another, already finish...
