I am using a sandvik 50mm r490 cutter - 1040 grade. Wanna get some advice to increase my tool life ... at the moment I do climb milling ... cause I thought that I wanna avoid conventional milling otherwise it creates too much heat ... which is as far as I know bad for machining stainless ... but entering the hard plama cut surface isn’t very good for the insert either .... should I try conventional milling .... or even maybe use a different tool ... maybe endmill - conventional milling ...just to get rid of the hard surface ... thanks in advance for any advice . Ben

I'm kinda with the using an end mill bent too. Only thing I can add is be sure to cut plenty deep so you're cutting beyond the heat affected zone. That is of course if you have sufficient spare material to play with.

Conventional cut with a doc deep enough to get under the crust. Might have to go a bit slower but be sure to get under it.

machining plasma cut stainless is a pain and killer on tooling as it usually creates chromium carbide preciptated at the surface. one or 2 parts, find the right cutter and feed it. if mass production, id be giving them a bath of passivation soloution first to remove the crap layer.
