Let's try this again , let's establish axis., y, x , and z. Z would be direction of the axis. Axis w would be rotating of the entire part. Are want to rotate ot move in the z axis?

4 jaw chucks are great, if in good condition. Each jaw can move independently. There fore adjust and true up the casting. Inside collet really depends the length and diameter size of the part. Hope fully they are boring and facing simultaneously. This will true up to each other. If there is an...

There is no added value to redesign existing flanges. And the reason is as posted by above of all post. This is standard reliable practice. Stick to what works and not deviate.

Use combination of ultrasonic inspection device. Measure the wall thickness, in the surrounding area not having corrosion. Take hand grinder remove one small area with deep corrosion. Measure with pin depth mic . Inspect the difference. Then decide

Let's take vote, I vote remove and replace

Here are some standard practices. Depending on the type of manufacturing. For machined parts guide Standard internal radii .015-.040 R Standard edge break .005-.025 Standard linear dimensions ÷/-.005, ÷/-.010 +/-.020. Reason is tolerance stack up. During manufacturing to achieve final drawing...

A good starting point is the manufacturer of the machine. Contact them for the settings. And procedure. Then AWS

I believe a 3D stress analysis would be helpful. As Well. There will be a cone around the bolt head, except for a partial section.

I agree with Dave's and your thoughts on AI. But not all books all equally. I could make a spread sheet from 45 years of experience as a guide. How ever it would be obsolete in short Time. When I started. I used manual machines. Manual engine lathe, manual turret lathe, Hand operated OD and ID...
