Greetings, All
I just finished cutting some parts from .375" Baltic Birch and thought that I would share some information that may benefit others in the future.
The odd shaped parts did not offer much surface area so I used vacuum (two Feins on four zones pulling 7hg) and tabs to hold them.
I only had exactly the amount of material that I needed so testing was limited. The following settings may be conservative, but they worked nicely for me and I had plenty of time figured into the job.
To cut the parts out I used a profile strategy (conventional direction) with a final pass thickness of .06" and a final pass allowance of .005"
Tabs were .060" thick. I cut the parts loose with a knife and then cleaned them up with a flush trim bit on the router table
Cutter Onsrud 60-113 .25" Compression
Step Down .25"
Feed Rate 4 ips at 15,000 rpm
Plunge Rate .5 ips
The cutter made no squealing noises while cutting and was a little above room temperature when complete.
Kind regards,
JIM
