Hi
Finally took the courage and started to cut some wood this evening after so much checking and double checking of a new replacment build.
Using a CRP2448 with the 2.2kw spindle i did the model in Fusion then output to Mach3.
I want to cut 'sapele' and i have set a 10mm Bull Nose cutter in an adaptive cut at 8000rpm and 3800mm/min. This seems to be what i keep coming too with various checks.
So i start the climb cut and it goes down to 10mm doc and as far as i can see 2mm width (although in fusion it says opt load 4mm), it runs sweet along the grain but when it went across it chattered like hell and i had to stop it.
It may be that i have not secured it absolutely rock solid and its that, but tbh i had got it much more secure than any i have done before due to the nature of the beast i am now using (used a High-z 720 before.)
Can anyone who may have cut this type of wood before offer any advise please
thank you malcLast edited by BernieNUFC; 21-05-2018 at 08:56 PM. Reason: 'climb' added

Sapele is quite hard. 10mm doc is probably way too much for an aluminium framed machine. Might work if your bit is razor sharp

The cutter is brand new, i would not normally cut to this DOC but the rave is that adaptive is able to do just that so hence why i tried it out :-)
cheers for reply

Machine rigidity is key to cutting capability.
You think that's too expensive? You're not a Model Engineer are you? :D

Ball Nose Cutters all suffer from zero cutting speed at the very tip, have you considered roughing with a straight cutter and finishing with with the Ball Nosed cutter?
