Investigation of geometric groove accuracy in micro end milling (2nd Report)

Fabrication of Microfluidic Channel Using Micro End Milling and Micro Electrical Discharge Milling

This paper discusses the fabrication of microfluidic channels using micro end milling and micro electrical discharge (ED) milling on metals and polymers. The width of the microchannels fabricated by micro end milling was 100-800 μm with 1-2 aspect ratio. The average surface roughness values were 100-200 nm and 80-120 nm on metals and polymers respectively. The end milling was found to form more...

Modeling of three-dimensional cutting forces in micro-end-milling

A new nominal uncut chip thickness algorithm for micro-scale end-milling is proposed by considering the combination of an exact trochoidal trajectory of the tool tip and tool run-out, and then the actual uncut chip thickness may be obtained from a comparison between the current accumulative uncut chip thickness and the minimum chip thickness. Due to the intermittency of the chip formation, the ...

Investigation of laser milling process characteristics for micro tooling applications

Modeling micro - end - milling operations . Part II : tool run - out

The effect of run-out is clearly noticed in micro-end-milling operations, while the same run-out creates negligible change at the cutting force profile of conventional end-milling operations. In this paper, the cutting force characteristics of micro-end-milling operations with tool run-out are investigated. An analytical cutting force model is developed for micro-end-milling operations with too...
