Speeds, feeds, plunge rates

What CAM tool are you using?

Current versions of Carbide Create have quite conservative feeds and speeds for many endmills in both hard and soft woods.

See Intro to CNC - Part 5: Feeds & Speeds - YouTube for concepts on this and see the series #MaterialMonday: #MaterialMonday on YouTube for specifics.

You should test feeds and speeds in a piece of scrap using the technique at: https://precisebits.com/tutorials/calibrating_feeds_n_speeds.htm

Another consideration is Climb vs. Conventional Milling and tooling engagement — where possible avoid slotting and add geometry and cut as a pocket (Making vacuum hose adapters and/or Adding geometry to cut as a pocket with a finishing pass ) and consider leaving a roughing clearance and taking a finishing pass.
