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...
متن کاملFpga-based Control System for Highly Dynamic Axes in Ultra-precision Machining
The developments presented in this paper focus on the implementation of an FPGA-based (Field Programmable Gate Array) hybrid servo control system for mechanically coupled highly-dynamic axes. Consisting of an FPGA-based low level part for high bandwidth control loops and a microprocessor-based high level part for setpoint generation, the novel servo system enables the control of highly dynamic ...
متن کاملDevelopment of Ultra Precision Machining with High Positioning Resolution
INSTRUCTIONS The technology for ultra-precision machining has been developed rapidly and steadily. In recent years, the demand for free form, complex and microscopic cutting has increased as a result of the need for highvalue-added fabrication for items such as high NA glass lenses, micro-grooves, diffractive aspheric lenses and other optical components. The ultra-precision machine for cutting ...
متن کاملPrecision 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...
متن کاملMachining Processes for Precision Molds
INTRODUCTION The continuing drive towards miniaturisation in a number of industries including semiconductor, optoelectronic and medical is stimulated by requirements which include enhanced functionality, performance and reliability, increased energy efficiency, a cleaner environment, improved healthcare, together with reduced costs etc. [1, 2]. Also, new products for fastgrowing industries like...
