It doesn't matter, the wheel diameter is going to change in time due to use so
it will effect the final part dims, this is why cam grinding requires multiple
passes [one reason].
I've seen machine tools that use lasers to measure wear on end mills and such,

Ries, I'm curious as to how you calculated or quantified your RIO on your
CAD/CAM package? I've been looking for a direct way
to do this for years, w/ little in the way of clear or concise results.
I completely agree with your assessment of CAD/CAM and it's level of
integration. I've done CAM
As a comparison I typically route wood at +/-100ipm [80-130 typically] and 1/2

you need to be cranking at 18K or so [using a 3hp spindle]. This equates to a
0.011 chip on a bit w/ two cutting edges (100ipm x 2)/18000rpm=

Just make sure the ones you buy are rated for the torque you need. The level of
transmittable torque is the weakest link in a HD.

Hey there Aram, I built my own router. I work as an industrial designer
build heavy equipment for steel mills and the like. Designing and
building my own machine was a natural fit. My router is 20 x 10 [ft]

Thanks VERY much for your help and advice..

My suggestion is to just replace the pinion as most of the wear is
there. At some point it maybe necessary to replace the rack as
well.
Of course if the amount of engagement is adjustable there may
well be a
lot more service gotten out of the pinions as well.
