Depth of Cut/Cutting Forces
Hey,
I haven't had much time to play around with this program yet, but initially it looks rather interesting and helpful.
I'm a bit curious about the default depths of cuts as well as the cutting forces. It seems that the default depth of cut for a 0.5" mill is 0.9029". Perhaps I am misunderstanding this parameter because I wouldn't use a depth of cut near that in wax... It also appears to not take the material into account when determining this so maybe that's a possibility in the future?
As far as cutting force goes, the values don't seem to make much sense given the depth of cuts for some different bits, but again I think I'm just not quite understanding what the DOC parameter is asking for. Any resource you could point me toward as far as acceptable cutting forces for various sized bits would be greatly appreciated. I do have the 23rd edition of the machinist's handbook, but have not yet had the chance to consult it.
Thanks for the time and any help you may have!

Hello,
Default depth of cut is material and tool type dependant.
Solid HP endmills (roughers) can take twise the depth of cut of standard generic endmill.
Tougher materials will give shallower deoths of cut raher than soft ones.
Also Recomended DOC (depth of cut) is dependant on length of the endmill and on WOC (width of cut)
The longer the endmill, the shalower cuts tou can take with it.
Also if you take small WOC, you are suggested higher DOC.
HSMAdvisor tries to balance the cut in such a way as to maximize productivity.
It can calculate how much the cutter can take and tries to maximise the output.
As to DOC being way high again it depends on lots of different things.
See my youtube channel for examples of various cuts programmed with my tool.
I am sure you will find cuts deeper than what you used to see before.
There is a link to it on top menu.
A lot of data is actually taken from books like MH and others.
Bye.

Alright, I must just not have had enough time to completely figure out how to manipulate all the parameters correctly. I've seen you're channel but again have not had a ton of time to really dive into it yet.
I appreciate the quick feedback and look forward to playing around with this tool more. It ought to be a great resource and I'm rather surprised there aren't very many of these sort of programs out there given the constant struggle to find optimum machining conditions.
Cheers.

The reason there are not many of them around is its a very limited market.
Also many machinists beleive they know better than any 'puter.
I have guys with 20 year experience dropping their jaw when they see in person how fast new tooling is supposed to run
