Your drawing showed you using "Climb" milling vs conventional milling direction. Climb milling can be problematic on some materials. You were climb milling. In climb milling sometimes the cutter will want to grab and walk up over the part if feeds and speeds aren't correct. There are Feed and Speed charts to determine proper cutter RPM and feed rate for for a given type of material. Using the charts, especially with new and exotic tooling inserts, saves unnecessary wear and tear on cutters and slitting saws. (and a lot of money) Especially on exotic materials like Stainless steels, Titanium, and alloys etc. there are also proper lubricant/coolants that are optimized for certain materials. If you are a newbie machinist guessing is a big mistake!! Get a used copy of Machinery's Handbook and do it right! you won't regret it. As a machinist the best investment you can make when new to the craft. Starting slower is better, too fast with a slitting saw makes it get hot, warps the blade and then it won't cut straight and bind up.
