Re: [SherlineCNC] g21 Metric on Sherline 2000 - feed units are?
- Hi John,
You could start by looking through the archives of this very list because this has been discussed before. There is a thread begun on Friday January 13th 2006 with message number 7645 entitled "Sherline Speeds and Feeds", but there is a lot more additional material avaialble by searching or even looking through past messages. This group has been going for 10 years so there has been a wealth of information exchnaged over that time.
Perhaps this might also help:
I would also suggest you try it for yourself starting with very conservative figures as regards depth of cut and feed rate and working up from there. I would encourage you not to begin with a small cutter such as 1 mm and to test with a cutter in the 6 to 10 mm range, small cutters require very high spindle speeds and extremely careful attention to depth of cut and feedrate there are just too many variables introduced with them for a beginner to handle.
Check your ego at the door, we all have to begin somewhere.

Thanks again. I was pretty sure that was the case, but I find myself fairly hard pressed to find any meaningful calculators or rules of thumb when it comes to speeds and feeds on a Sherline 2000 when running in metric… my Google chops are failing me.
If anyone has any pointers that might get me started with test cuts that won't cost a fortune in time, tools, cash or ego, I'd truly appreciate learning about them.
