Superprecision machining method using fine particulates (Elastic emission machining).

Effect of focusing flow on stationary spot machining properties in elastic emission machining

Ultraprecise optical elements are applied in advanced optical apparatus. Elastic emission machining (EEM) is one of the ultraprecision machining methods used to fabricate shapes with 0.1-nm accuracy. In this study, we proposed and experimentally tested the control of the shape of a stationary spot profile by introducing a focusing-flow state between the nozzle outlet and the workpiece surface i...

Rapid Prototyping using CNC Machining

Although current rapid prototyping methods have had a significant impact on product and process design, they are often limited in both accuracy and choice of suitable materials. Also, the current methods share little similarity to typical manufacturing processes. In this paper, a method for using CNC machining as a Rapid Prototyping process is described in order to exploit the creation of funct...

Feature-Based Machining using Macro

This paper presents an on-going research work on the implementation of feature-based machining via macro programming. Repetitive machining features such as holes, slots, pockets etc can readily be encapsulated in macros. Each macro consists of methods on how to machine the shape as defined by the feature. The macro programming technique comprises of a main program and subprograms. The main prog...

A Method for Machining Metallic Foam

The present invention relates to a process of cutting metallic foams that eliminates the problem of smeared surfaces. When a traditional machining approach is used, the surface of the material smears, causing the surface pores of the foam to close. Evidence of this is shown in the traditionally machined sample shown in Figure 1b versus the uncut TM shown in Figure 1a. In contrast, Figure 1c ill...
