G34 rectangular box key program help

[Superiorforge]

Hi guys I am very rusty when it comes to manual programming(I always used work NC to generate my programs) I am on a Giddings and Lewis post mill using a GE Fanuc 160I control.I am trying to program a rectangular box key 4" long by 4" wide with a depth of 2 inches could someone write a program example using those dimensions.That would help me get started as I have alot of different box keys to do.My company is to cheap to buy mastercam or any other conversion software.Thanks Shawn.
