So I’ve been reading up and watching all things feeds and Speeds and can’t seem to wrap my head in understanding what to do. There are times I hear my makita router make high shiver pitch sounds that is just as annoying and nerve wracking. Not sure if its caused by the bit going against the grain or not.
I typically just set the rpm from what CC or Vcarve pro says and let the software do the rest.
What am I missing?
With CC the rpm is at approximately 10k rpm.
With Vcarve pro the rpm is at 16k or 18k rpm.
What I understand is it’s about the chip load and to derive at the correct chip load depends in the rpm and feed rate (ipm). Then there is depth of cut (doc) which should not exceed no more than 50% of the bit diameter.
