Full depth cut with end mill?2/1
Hi guys, just wondering how everyone runs their end mills. I have a Guhdo 19 mm chip breaker (not rougher) that I use for my roughing workhorse. I usually run it in helical tool paths for side roughing out of my material. I usually take off anywhere from 1/8" to 1/4" of material from the side, with a finaly cut depth of roughly 3". Does anyone just say the heck with it and and use full cut length engagement with one pass? How does it behave for you? Most of our parts are screwed to MDF and placed on pods, oak and poplar mostly, some white oak.
I always rough it out and then run a finish pass at that thickness.
The thought off going right to depth with a finish cut has never been considered and probably never will be.
Hope this helps,
I'm was never interested in torturing the spindle that much, to make a 3" deep cut in one pass.
What material? What kind of work? 3" depth of cut in foam? Sure.
Read the last sentence Mark B.
This is theoretically possible, and the tool wouldn't even likely mind, however, you'd need a fairly high torque/high HP spindle to do it at any speed. This is just ignoring any runout/tram/vibration/etc related issues. and sticking to "can my spindle physically do this".
The calculations are not perfect but should tell you what is theoretically possible. You need to get into the torque calculations to get a real answer.
The real answer is probably somewhere between 10-20hp for the above, depending on actual (not bullshit) spindle torque and RPM used.
If you want 200ipm, double it.
I just think in terms of much time it took to load the part and I preach this to the staff. I donít want shredding. I want completed parts We take up to 6 passes just to lengthen tool, spindle life etc.
We have 40hp travini on one cnc that we had to just go to return onion skin to hold the pieces because of ipm to increase tool life.
We are running a 25 horse Beckhoff spindle with hsk 63 f collet holders. The op in question is only for dimensional roughing
