Cutting force denoising in micro-milling tool condition monitoring
International Journal of Production Research, 2008An independent component analysis (ICA) algorithm for cutting force denoising was applied in micro-milling tool condition monitoring. In micro-milling, the comparatively small cutting force signal is prone to contamination by relatively large noise, and as a result it is important to denoise the force signal before further processing it.

Analysis of tool deflection in micro milling of graphite electrodes
The International Journal of Advanced Manufacturing Technology, 2013In this paper, the tool deflection is first analyzed analytically, based on a four-section cantilever beam representation of the tool. Contributions of different sections of the tool to total tool displacement are quantified. Then the influence of cutting parameters (width of cut, depth of cut, and feed per tooth) on tool deflection are investigated ...

A machine vision system for micro-milling tool condition monitoring
Precision Engineering, 2018Abstract Tool condition monitoring is a key issue in micromachining for part quality control because the excessive tool wear and abnormal tool conditions will significantly decrease the size accuracy of part and shorten the tool durability as well. In view of this, a novel configuration of machine vision system for online tool condition monitoring is

Effect of tool wear in ultrasonic vibration-assisted micro-milling
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2013This article presents an experimental study on how tool wear affects tool life, surface roughness, and burr formation in ultrasonic vibration-assisted micro-milling. Small amplitude of vibration (2 µm) is applied to the micro-tools to evaluate the cutting performance influenced by tool flank wear as the cutting lengths increase.

Sensor Fusion Based Tool-Workpiece Contact Detection in Micro-Milling
2015Information about distance between tool and workpiece is crucial for proper machining process. In micro-milling, due to very small tool dimensions, observation of the tool position with regard to the workpiece is possible only with a microscope. Exploiting of different signals obtained during micro-milling process in establishing the tool-workpiece ...
