Feb 06, 2009· The tool's lengthtodiameter ratio is significant in any milling process. The larger the ratio, the less rigid the setup. However, the difference in performance between different levels of L:D becomes even more pronounced when tools are particularly small. This video shows machining footage involving tools as small as 0.008 inch in diameter.
