Ultrasonic elliptical vibration cutting has recently been utilized in industry for finishing of various precision parts such as mirror surface finishing and precision micro machining of dies and molds. However, its application has been limited to high-cost ultra-precision machining, where depth of cut is typically in a range from a few micrometers to several tens of micrometers due to power lim...

As a part of the development of a new design process of close capture exhausts systems for machining devices, based on fluid flows modeling, an experimental apparatus was realised, which recreates a machining operation in experimentally controlled conditions. The properties of the obtained spray of solid particles were entirely characterised using Phase Doppler Anemometry (PDA), in order to be ...

Reduction of energy consumption has played a significant role in industry. This paper describes a study on reducing energy consumption by machining process improvements. Methods of reducing energy consumption in a manufacturing line consisting of multiple machines are verified. First, to consolidate the processes, a series of horizontal machining centers are replaced with a 5axis machining cent...

Machining processes in the industry of today are rarely performed using industrial robots. In the cases where robots are used, machining is often performed using position control with a conservative feed-rate, to avoid excessive process forces. There is a great benefit in controlling the process forces instead, so as to improve the time-efficiency by applying the maximum allowed force, and thus...

A facility for rapid prototyping of MEMS devices is crucial for the development of novel miniaturised components in all sectors of high-tech industry, e.g. telecommunications, information technology, micro-optics and aerospace. To overcome the disadvantages of existing techniques in terms of cost and flexibility, a new approach has been taken to provide a tool for rapid prototyping and small-sc...

Recent evolutions on forging process induce more complex shape on forging die. These evolutions, combined with High Speed Machining (HSM) process of forging die lead to important increase in time for machining preparation. In this context, an original approach for generating machining process based on machining knowledge is proposed in this paper. The core of this approach is to decompose a CAD...

Pamali, Abhinand P. Using Clothoidal Spirals to Generate Smooth Tool Paths For High Speed Machining. (Under the direction of Dr. Yuan-Shin Lee.) We present a new and innovative method to generate Contour Parallel tool paths using Clothoidal spirals for 2.5D pocket milling. The tool paths generated by the proposed method are more suitable for High Speed Machining compared to the traditional tool...

We present two methods for process planning of 2.5D machined parts. The first method is based on feature recognition from a 3D model. We embedded the shape and the machining method of two generic classes of machining features in a set of OPS5 rules to form a machining feature recognizer. When successfully recognizing a machining feature, machining instructions, in terms of the tool entrance fac...

The use of a minimum quantity of lubrication (MQL) with extremely low consumption of lubricant in machining processes has been reported as a technologically and environmentally feasible alternative to conventional flood cooling. In hot machining, the external heat source is applied during machining that will assist to increase machining performance. Many external heating techniques are availabl...

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...
