What is the proper technique for squaring / shaping the 4 sides of a 3/16" steel plate. I've never worked w/ steel before only aluminum and never played around w/ thin plate material. I've got a piece of 4142 pre hard (hardness 28-32) steel plate that I need to square the sides w/ my manual milling machine.
How would you go about clamping the plate and squaring up the sides?? Would you lay the plate flat or upright in the vise?? What type and size of tooling would be best for this. What about RPM and feed rates??
I know this is a basic milling project and I have just about enough machining knowledge to be dangerous...........Thanks in advance
