Get QuoteSep 23, 2013 The limiting factor in the light, hobby, chicom stuff is machine rigidity and weak quillsspindles. The older machines are about 0.01 mm in accuracy or 10 microns. Limiting factor will be end mill deflection, at the end. The modern VMCs are about 5 microns - 2.5 by factory specs, and so a bit better than the old ones.
Get QuoteHowever if you dont work the CNC router too hard any errors in the finished milling process will be minimal, and achieving sub-micron precision in a material such as timber is probably a moot point anyway.

Get QuoteClimb vs Conventional Milling Assume Nothing About Which is Best for Finish. This is a complex topic. Climb milling reduces cutting forces and ordinarily that would be the best answer for finish. But, climb deflects into the wall and conventional does not.

Get QuoteOct 12, 2011 Its very common in Australia where we have been working in mm since the 70s and are culturally prone to lazily abbreviate to say things like thats a couple of mils too big meaning mm. Also mill is a very common piece of equipment, AND a common workshop verb, that just happens to be closely tied with measurements.
