I believe specs for that bit are 150-200 ipm / .004-.006 chipload / 20K rpm
At your 300 ipm & and .37" DOC what rpm and chipload are you at?
I’m curious b/c your DOC is 1.5 X tool diameter…
Isn’t chipload et al independent of DOC? I thought DOC was limited only by how much horsepower you could dump into the bit…
It’s my understanding the standard calculations are based on DOC being the tool diameter.
Amana, for example, list the caveats for reducing ipm when running deeper.
Depth of Cut:
1 x D Use recommended feed rate
2 x D Reduce feed rate by 25%
3 x D Reduce feed rate by 50%
Well this combo works great. Thank you.
It was with the pseudo-equivalent Whiteside UD2102 compression bit.
Obviously needs a good dust collection setup to avoid re-cutting chips during the second pass.
I’ll have a go with some of the other suggestions as well.
Awesome…glad to hear! Don’t hesitate to reach out in the future!
Hack,
Are you running this bit at Whiteside’s recommended 20K rpm?
That’s a .0075 chip @ 300ipm - much bigger than their recommended .004-.006
Not doubting your success…
So interesting that Amana recommends a .0031 chip for their equivalent 2-flute 1/4" compression bit… flute depth play a role here maybe, bit design balancing core rigidity, chip and extraction characteristics?
I am running it at 18000 rpm currently. I did not really calculate the chip load tbh. Just sounds good to the ear and I am getting good cuts. I will have to watch bit life to see if adjustments need made.
I’ve recently been using this bit and I’ve been really impressed with it.
Single pass in 3/4" BB plywood with no need for tabs.
18k rpm, 60 ipm, 35 degree ramp
Very clean
