    I remember most of that, but you are wrong, the Navy could afford them TOO! I helped install an NC mill on Mare Island Naval Shipyard in 1965. I had the keys to the shop before I retired in 2005, now all I have is my home shop with a CNC mill a lathe and a Bridgeport W/ digital readout.

    I can remember translating tapes many years ago, but with the new machining methods we have now it's better just to just use the blueprints redraw in a CAD program and go from there.
    I remember when all the programs were tool path and you HAD to use the right size tool to get a part that had the right dimensions. Now you have tool offsets right on the machine and the tool dimensions can be adjusted for. Back when tapes were punched you had to program toolpaths from point to point and if you went around a corner you had to choose the type of corner you wanted (sharp, rounded or just remove the sharp edge with a .005" 45 deg nick) and then calculate the tool path to make it. To round a corner you needed to figure out where the cutter needed to stop going straight and then where it would end up after going around the corner plus where the center of the arc was from where you stopped going straight. Now you can just tell the CAD program to round all corners and you are done. If you want to try something fun program the rough and finish cuts for a pocket shaped like a triangle (3" length down one side - point to point) with none of the sides either horizontal or vertical, do a step over of 75% and leave .02" for finish using a .125" end mill.
