Used a two flute 1/4″ helix-shaped hss cutter which may have been a bit dull. The feed was very slow and the job shown above took 2.5 hours to complete

Ramblin Rollers sign V1

There was a lot of tearout on the first try so we lowered the feed rate quite a bit and also realized that on the first cut we were using an upcut bit rather than the desired downcut bit.

 

With a slower feed rate and a downcut bit the results were much better.

Nathan RJ’s settings and results.  A feed rate of 1 inch per second worked well.

 

Diego changed the feed rate to 150 inches per minute and it cut just as smoothly and the chips look better:

Good Afternoon Joe,

I just talked to Matt, and according to him  the answer to your question about locking the B  Axes is no,  Please try cutting your material at a slower rate, and that should take care of your issue. Please feel free to contact us if you have any further questions.
