Hi. I am a little conserned about wood chips wrapping around my bit (It seems that the bit is strong enough to get rid of them, but one time it got really tangled up so I had to pause the job and clean it), I was using a 1/4 up cut bit at 18.000 R.P.M 40% stepover and 60 feed rate doing a roughing pass on oak following the grain. What can I do to avoid this? Should I go against the grain?
Here is a video of this happening:
Thanks.
assuming the bit is properly sharp, I think the feeds and speeds need some tweaking. ideally you want chips. Play with the +/- 10% controls and the spindle speed to see what works for you. The video sounds off to me.
Are you positive this is oak ? (I don’t know, the color looks very light to me)
I’ve have some woods turning out to be stringy
Cutting cross grain should help, as well as using a downcut endmill. 60ipm @ 18.000RPM sounds like reasonable feeds and speeds, but it’s probably either the wood or a dull endmill.
That looks very much like Birch. I get similar strings, particularly with smaller bits. Cross grain would eliminate most of that.
So many variables
Have you looked at your stepover , maybe a larger stepover would create chips feather than what you have
I had same issue and speeding up the feed did not help but a larger stepover did as it was cutting more wood rather than shaving the wood
Just my opinion
