Noob facing question

[MBX5]

Hello....noob facing question here...bare with me....

Running Fadal 4020HT....10k rpm, 20hp. Bt40 holders.

I have a 12 x 12 x 2" thk A-36 plate that I need to square and face.
The plate is flame cut and has rough edges all around...

I am wondering what cutters to use in squaring and facing. I have pockets to do and have an SGS Z-Carb AP cutter 3/4" for roughing and finishing the pockets....

I am not sure what to use for facing - indexable cutter? What brand would be ok for someone who isn't doing full production constantly?

Also - do I have to worry about "hardening" due to flame cutting process or should that not really concern me? Would I use an indexable cutter to face all the flame cut faces?

Thanks and any advice would be greatly appreciated!!!

4" face mill with indexable inserts,( I like sandvik but any quality ones will work) for the sides a 3/4" solid carbide 4 flute 2.5" in length,
but first on the sides clean them up with junk endmills and just offset the cuts to the side a tad as you go deep so you dont rub the non cutting part of the endmill. then take your 3/4 dia endmill and run a finsh pass, this way you dont screw it up on the interrupted flame cuts

then suface grind the top or lap it

The heat affected zone from flame cutting can be NASTY, especially with higher carbon steels. Delw has a good suggestion in the junk end mill removing junk metal.

I keep all my broken/ worn out endmills just for that purpose. jagged edges/inturupted cuts and flame cut stuff.
