Cutting 3/8" Baltic Birch

[jim_vv]

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
