I’ve seen some Excellon files that have a format like this…
%
T1C0.0350F200S100
X-007350Y001700
X-000160Y001700
.

Does anyone know what the “F200S100” means?

I think that indicates the spindle speed (rpm) and Z-axis speed (how fast to lower the drill bit). [APCircuits has a summary. I would think that most manufacturers would want to supply their own values for those parameters…](http://www.apcircuits.com/resources/information/nc_codes.html)
