I just ran a quick one-shot job off the 1100.
A dozen CRS (1020 ?) steel blocks. needed a slot taken across them in the middle. Blocks were 3" long, 1-1/2 wide and about 1" thick. The slot was across the 1-1/2 axis, 1-3/8 wide and .400 deep.
3/8 dia 4fl coated endmill, 1.25 sticking out. (what I had available, pretty much new)

Now normally I run aluminum and stainless (300 & 400 series) so it's one end of the spectrum and the other. These steel parts were an oddity so I played with Gwizard and come up with .050" DOC, 3000RPM and 5ipm feed
On the machine I ended up bringing the rpm down to 2200 and the feed to 3.6 to get a decent sounding cut. Now the first path through was full slot width and each one after was .260 width so I could have stepped it up but I just ran the pieces off.

Cycle time ended up somewhere near 18 minutes per.

Anyway, parts are done and gone and it's no big deal, just seems pretty excessive but was curious how others would have approached this
