 This is just one example of why you MUST NOT make engineering decisions based on assumptions. You should check/measure your parts and make appropriate design adjustments. - Stu Bloom [more] |

Re: Waterjet accuracy?
If you look at the detailed dimensions of a AM or Vex gear box, they typically run + 0.003" to .0005" large between spur gears. In terms of reaming, we use a 1.125 as that's what's available.
This year we waterjet cut the entire structure of our robot. Accuracy would depend on the actual machine and it mechanical construction. It would make excellent gearbox plates. |
