On the heels of the previous post.

YouTuber Breaking Taps has just published another of his interesting videos:

In it he is testing various High-Speed Machining techniques on his benchtop CNC router.

Also it is mentioned that HSMAdvisor does not seem to like those small high-feed cutters: at some point some calculated values become negative.

This is a legitimate criticism and it actually happens because default cutting depth of 0.024" becomes too large for the 0.24" Lakeshore high feed and mill and an actual Flute length of 0.015" must be entered in order to get proper values:

With actual 0.015" flute length entered the recommended speed and feed values are now in the safe end of the ballpark suggested by the manufacturer.

Task added to the issue tracker!
