@charlie_wallace that’s one heck of a tool right there. It returned crazy numbers though, 1.5875mm depth, 10000 RPM (seems reasonable), but 914.4 mm/min feed rate?
@Andy_Meyer so that is the proper feed rate for the tool to get the right chip load and cut the most efficiently. like i’m doing around 1200mm/min so it sounds about right. the problem is, can you achieve that rate and cut ok. if not you either have to lower the RPM or less flutes, try putting in 1 or 2 flutes for the tool type on fs-wizard, or running a larger tool if you can. that program tells you what you should be doing, so now you just have to adapt it to what you can do.
cheers
@charlie_wallace I might be able to pull 500 mm/min if I’m lucky, but my spindle couldn’t handle it, probably. Thanks for all the help!
@Andy_Meyer no worries, http://blog.cnccookbook.com/2012/12/23/why-use-a-single-flute-end-mill/ good article on single flutes to help with this issue. as an aside you can also run into the issue of aluminium welding itself onto the bit if its running too fast, the tapping fluid will help with that though. a9 also smells better
