I'm making Luiz Ally's slim vise. I'm cutting the pieces out of a 3.5 x 8 x 1/2 inch plate of aluminum.
I'm using a .250 HSS end mill, 4 IPM at 2500 rpm, .050 D.O.C., .120 step-over, and two operations, first a spiral roughing leaving .010 for a profiling finishing operation and then a two pass full depth profiling at .005 per pass. The time adds up to about 6 hours.
I'm using my approximation of Terry's excellent no-fog mister.
6 hours is a long time to sit there and watch it. I'm running with a pretty peppy PC and LinuxCNC.
The Sherline motor reads 140F in my non-a/c garage here in sunny Delray Beach. But it doesn't seem to get any hotter with time.
Questions:
1. Do I really need to give this my undivided attention?
2. Would any of you let this run with a look-see say every 1/2 hour?
3. What if I inserted pauses in the g-code say every 30 minutes?
4. What if I paused the LinuxCNC, turned off the mill, did somthing else, then turned the mill on and continued? I've tried this on other things and didn't seem to lose any steps, but ???
I encourage criticism here. I do want to cut the parts at once, mostly to improve chance of getting consistent dimensions on the two jaws.
