Improper resulting outputs on a 1045 steel case

Hello,

Using trial version, so far have had good results and enjoy the GUI!

The following screenshot shows outcomes I received that were excessive on feed rate and surface speed.

For reference included is the HAAS chart for this HMEIM tool, a compact 5 flute 3/4" index mill.

Observations:

1. At 140m/min this tool performs correctly, good surface finish and blue chips

2. At their (HAAS) recommended 90 m/min there is BUE and poor outcomes. Their chip load is also 4x lower than HSM's recommendation (partially because this is a compact 5 flute).

3. I can imagine that with blue chips at 140, attempting HSM's recommendations (attached) would be over speed, 4400 to 13k RPM defies my normal logic in this regime.

Please let me know what is going on with this, thanks.
