download Fusion360 its great for just about everything from Design to Manufacture and its like only 20 bucks a month . And does a great job posting a file for just about any machine easy to create a threadmill program
Five passes??? That's nuts. One pass for fine threads and two passes for course. Especially on a size like this. (Note this will not be relevant to every single material out there.) Try to get used to programming thread milling in incremental. One small sub can do a hole at any location, as long as you start the tool typically, but not necessarily, centered above the hole. For the two pass version, just set up a different D address comp for each pass. Cut something around 70% of thread depth the fist pass and full the next. You most definitely will need thread gauges for thread milling, as you'll have no multi-million dollar tap company working for you to make things just right.
