This got me thinking
schmidtmotorworks said On a master at 0.0001" and 0.1 degree steps, the faceting is noticeable and needs to be polished out.
I did a CAD test. I used a 30 mm circle and wanted to see how accurate a step I may need. The cam is not a circle but if I put in a 'safety' factor of 2 or 3 for the ramp, I should be in the ball park. So if you traverse a circle in 0.1 deg increments, how much does the X axis have to move.
At 0.1 deg increments, the X axis has to move 0.000028 mm on a 30 mm circle.
Even at 1 deg movements, it is only 0.0023 mm Say the cam has a really steep lobe and it is 5 times that rate, its still only 0..01 mm.
Where am I going wrong ? It looks like 1 mm steps will be more than accurate enough.
