n How to defined (0.6; 0.3) at 30 um removal?
- What kind of indicator for judgment? e.g. spindle current, roughness, die strength, wheel wear out?
- Why use 2 steps instead of 3 steps?
- Any available data of process window confirmation for feed rate? e.g. (0.7; 0.35) or (0.5; 0.25) at 30 um removal.
n Base on the defined feed rate, is it sensitive for thickness variation?
- For example, if we met some instable IPG issue. It caused randomly over-travel 10 um at GR2 (total removal 40 um)
