Hey all, so i am machining some 1/4" bar stock of C36000 (360 half hard) Brass and when i cut the slot (only one end is open) the part naturally is springing open. I assumed it would but not as badly as it has. Closed end measures 1.730 open end after cutting is measuring 1.76-1.77. I tried placing the open end in a vice and closing it on joe blox but i have a large run and that is not repeatable enough for me to leave it to the floor guys to replicate. Does any one have any suggestions? my thoughts are as follows:
Would annealing help?
Would grain direction make a difference to this? (slot runs with the grain)
I could buy over sized material then cut a small slot, open vise, machine outside and slot to size..etc (i was trying to avoid turning this into 4-5 ops)
tolerance on slot is +/-.001
any ideas would be great
thank you
