So, yesterday I had finally time to make something beside chips. I tried to make a pair of parallels, square a block, and make a pocket. I am still trying to understand mostly how to optimize things in the workshop, what I need and what I do not need. Here are my observations.
1) I am a bit lost without a DRO. It's kind of difficult for me even to read the scale I have, as it is most of the time covered by the vice.
2) I made a pocket 63x40mm 20mm deep. For using this I made plunge milling using a 16mm endmill. I was using a 300rpm. This operation created strong vibrations. It managed to move the head out of the axes and I think also the vice. The table was shaking. I was not brave enough to check if pushing the RPM would make things better. I understood I need to move the machine on a new table and this must be heavy. I am not sure if this can be optimized changing the overlap strategy.
3) I am using Feed and Speed from the CNCCookbook. I am a bit puzzled by the results, as most of the time it tells me to go at the maximum of the RPM and feed. This does not really match with what I see, even if I set up the software with the most conservative configuration.
4) I tried a 50mm face mill and it works OK, the surface it's not 100% mirror, I can still see the cutting circles, but it's acceptable.
5) One thing I feel it's missing is the boring head.
6) One thing I learned is to cut bigger pieces, as my parallels are too short, after I cut out the part I used for holding them.
I would appreciate your comments, as most of you have probably been there.
Regards,
Davide
