Having a little issue with machine and will do my best to describe what is happening, i have been cutting wood and every now and then the routed bit is juddering as if it is not able to cut quick enough, i am using my #201 endmill form C3D so it could be that it is just getting blunt, but i wonder if someone could explain what chatter is as i think this is what i may be experiencing based on some reading / investigation i have done.
Thanks for reply, I ran the same Job on stock etc only thing I changed was the bit and it is working like a champ so must be my bit is now dull or dulling. I have done loads of cuts on it since I had the SO3.
