Rockwell B scale

[BrianP.]

I have a job I am looking at for my boss. It has a call out on it for ........

From what I have been able to find the Rockwell b scale is for softer materials. The part is .750 square and .300 thick but has a .001 flatness call out on the bottom with a .002 parallelism to the bottom of a .656 pocket. I am wondering if I should rough, anneal and then finish machine or will it be too hard to machine after.

Rockwell B scale is for softer materials than the C scale.

anneal= as soft as possible.

seems customer needs to correct their callout.

Thanks. Kind of what I thought I was getting on what I read. Not real hard to confuse me though. 🙃
