So chatter is caused by the Milling machine and not the actually part. |
Not true. Usually the setup, speeds/feeds, and tooling are to blame. Most chatter can be eliminated with heavier chiploads coupled with lower sfpm, reguardless of what machine it's on.
The reason for my asking is I have a thin walled monolithic structure which I want to vibrate rapidily, however I believe that this is not called chatter due to the source. The source being the thin wall feature and not the machine and the tool.
I use a tuned carbide 1/2 4 flute straight cutter with 3 in over hang. So I guess I should have explained my better the first time. What are your guys thoughts on this.

The thin wall feature should work well, after you get your speeds/feeds set.
Don't be shocked to notice that on finish cuts, you could end up at 1500rpm at 15ipm with that 1/2" EM.
