That's on my list to try!
I made a rotational-to-linear translator with adjustable linear depth using 1/4" HDPE and a gigantic OMAX waterjet cutter. The pitches were perfect to within 0.0001", but the design was five layers of gears, some were planetary, others slid on cams. Trying to connect planar gears is very effing hard when you can't use a pass-through collet (e.g., the pinion has to be FLUSH but yet allow rotation).
- alacombe 6y agoI doubt you can get 0.1 thou tolerance out of a water cutter.
- tejtm 6y agoI would suspect GP is referring to precision as amplified through the gear chain
- SoSoRoCoCo 6y agoSorry, I was off by one decimal place. http://info.omax.com/precision http://info.omax.com/precision Average of ±0.003" (±0.08 mm) and up to 0.001” (±25 µ) About the same as a laser cutter. You set it to cut very slowly and it angles the head to account for motion and material deformation (you need to program the type of material).
