    Default Hex Programming

    Can someone help me i have a Daewoo Puma with a Fanuc 21I-TB control and need a program to hex the end of a part. The diameter across flats is 3.490. I plan on using a 5/8 endmill in the z axis live tool holder. I plan on the diameter before starting to be 4.402 and the hex needs to be .63 deep. Any help would be greatly appreciated.
