My team got an Omio X8 router at the beginning of this season, and we are slowly trying to be more efficient at using it. Please bear with me here, as I am definitely new to manufacturing and such (this is the first CNC machine my team has successfully used).
When we first got the router, people in the CNC router thread here said they were able to cut at ~40ipm at ~.05" DOC with a 4mm Huhao endmill (if I recall correctly). When we tried to step up our feed rates to get to this number, we were not able to get anywhere close with our setup before bits started breaking. During the season, most of our parts were cut by a 6mm Huhao endmill at 0.0625" DOC at ~25ipm. When we tried to push it any faster, our bits would start breaking again.
Just recently, I saw the post below:
Our setup is not dramatically different from what is shown here, but there are a few potential differences. First, our coolant setup is just the operator spraying some water-soluble coolant from McMaster with a spray bottle (no auto misting setup for us yet). Second, our router is not very well secured to anything – it sits on a table and it’s not bolted down.
What differences could lead to such dramatic differences in cutting speeds between the OzzyBoards video (and the recommendations from before the season) and what we’ve done in the past?
