I read from that information that you will probably want to do profile cuts 0.75" deep (all the way through?) with that 1/8" endmill ?
While the 22mm length of cut would allow it, slotting 0.75" with a 1/8th endmill in hardwood could turn out to be a big challenge. Even more so because you reference a compression bit, which has poorer chip evacuation than a regular upcut endmill
That said, here’s a summary of how I would approach the feeds and speeds, as mentioned in the ebook:
- pick a RPM value, the highest you can bear (with respect to loudness). When using a trim router my goto value as a balance between noise and efficiency is 18.000RPM
- select a target chipload. The ebook has a guideline table, but basically 0.001" is the answer in most cases, at least for a safe starting point
- feedrate is then derived from RPM, chipload and number of flutes, like so:
Feedrate (in ipm) = chipload (in inches) x RPM x number_of_flutes
so that would be 0.001 x 18000 x 2 = 36ipm in this example.
- plunge rate in hardwood: 30% of the feedrate should be fine in most cases
- depth of per pass: stick to 50% of the cutter diameter or lower. In hardwood, and considering the fact you will likely be slotting, I would say stick to 1mm or less with a 1/8", and 2mm or less with the 1/4"
As you experiment, you will be able to increase feedrate/chipload, and possibly depth per pass. The machine will tell you when you are entering the danger zone (shrieking sound/chatter)
