Laser-assisted machining process simulation for precision mould/die manufacturing

Microfactory -novel Manufacturing Systems for Precision Machining-

1. FIRST PROPOSAL; MICROFACTORY “Microfactory” was a concept of a future manufacturing system, which was proposed in the Japanese national R&D project named “Micro Machine Project [1].” The original concept of the microfactory was a super-miniature manufacturing system that consists of miniature machine tools and manipulators. In 1999, AIST developed the first prototype of a microfactory. (Figu...

Process Monitoring and Control for Precision Manufacturing

New demands are being placed on monitoring systems in precision manufacturing because of recent developments and trends in machining technology and machine tool design. This paper first discusses the requirements for sensor technology for precision manufacturing process monitoring in general. Then, background and details are given about acoustic emission (AE) and the application of AE sensing t...

Modeling and Simulation of a Machining Process Chain for the Precision Manufacture of Polar Microstructure

This paper presents a functional microstructured surface, named Polar Microstructure. Polar microstructure is a three dimensional (3D) structured surface possessing a pattern of distribution of latitude and longitude micro-topographies with geometrical characteristics, which is similar to that in the Earth’s north or south pole. The spacing of its small surface features can achieve form accurac...

Precision flexible machining cells within a manufacturing system

The conceptual design of a manufacturing cell for a small-batch manufacturer is duscussed in this report. The cell produces small parts with dimensional tolerances of ±.005 inch (.13mm) using a minimum of machining equipment. The cell design emphasizes near-term technology and uses off the shelf items where possible. The proposed cell can run unattended for a moderate period of time (eg. over-n...
