Genral tolerance = Unless specified tolerance So once you add Max or Min Radius, it was specified

I guess it refers to a region of the forging that experiences the highest mechanical stress during its intended service, which means different depth(t) will be applied on different parts

440C, high abrasion resistant + stainless steel

Thread inserts like we common used in aluminium castings are more stronger than aluminium threads, you can make the inserts much bigger than thread size, and add multiple groves to avoid to be pulled out.

Cant see the thickness, but its a really challenging project for only bending, as I can see thickness according to drawing scale. Use thicker material and grinding after bending is a not bad idea.

Cause 3# is very rare in CNC program. Machines are more trustable than human beings, 99.999% CNC defects are caused by human factors. In factory, if there are a complex CNC processe involve multipe clampings, especially for large quantity orders, factory will use more machines, each machine...

Windows 11 system, my CATIA is V5R21

Two galvanization methods, hot galvanization and cold galvanization. Its helpful but not necessary to added anti-rust oil on cold galvanization part, because anti-rust performance of cold galvanization is not stronger enough for severe environment, its salt spray test time is 24-72 hours...

Try to use guides instead of coupling

This is a part we are producing, using 17-4PH H1075

Different thickness will have different effects on heat treatment. Compare the hardness, depth of hardness between part and specimens, maybe helpful to know the reason

No need to worry about fastening force of shoulder screw if make it like this.

If you use Electric torque wrench, do not design according to 216Nm, its just a static torque, impulsive torque while tightening must be considered.

It'll be better to machie threads before heat treatment, to reduce stress while machining.

Sure, like these
