Technical Q & A

Feeds and Speeds
Here is the best info we have here in support. This is one of the hardest things for people to get right as it is a learned skill to come up with and adjust feeds/speeds. There is no set in stone number for any project:

The info I am providing is on feeds/speeds and calculating them using chipload. I am including some document links and want to throw in a couple of reminders that chip-load values are key, so finding you bits chipload from the manufacturer and then finding the federate plus 12k-18k rpm that gets you the chipload:
A good place to start -http://www.woodguide.org/files/2014/...bit_basics.pdf

A good reminder to use chipload calculations -http://www.talkshopbot.com/forum/sho...-find-the-data

And an extra reminder that chiploads are based on a 1x full depth cut. 1x full depth is the diameter of the bit. So a ¼” bit has a 1x full depth of cut of ¼”.
