I’ve got an upcoming project I’ve been thinking about, and I decided to do a little proof of concept since I was making a stand for my drill press.
It turned out ok. It’s mostly plywood from the scrap heap that was way past it’s prime, so it’s not great. I used a 90 degree v-bit at 100in/min. I started out around 20k rpm, then when I noticed it start heating up I played with the speeds some… Didn’t help. There’s some pretty gnarly scorching throughout.
I really need to get these feeds/speeds down before trying to tackle nicer projects. I’m thinking about a database of decent feeds/speeds for different bit types and materials that we can all contribute to, but I don’t have the skills (yet) to make it happen.
Also, does anyone know how to change feedrate mid-job on ugs platform? There’s already been a couple times I’ve wished I could.
