Old Guy CNC

Hi. I'm David. During my working career I was very fortunate to do 3 things that I loved: machining, (C)NC programming, and software engineering ("jack of some trades, master of none"). When I started in the '70's, "CNC" was fairly new and "NC" was the norm. CAD/CAM was really in its infancy back then and we did all of our NC programming using a computer language called APT. We used teletypes to enter our code, compiled it on mainframes, and punched the g-code on paper tapes which was read by the machine tools via reel-to-reel controllers. I've always been awed by the smarter-than-me folks that imagined, designed, engineered and built the machines, computers and software that we have today. I hope someone can make use of my app "ShopSolver" (which I dearly would have loved to have back in the day when running and programming Tree Mills and Hurcos), and continue to learn along with me. Thanks for watching!
