Threading Reference

[jlv3901]

I know everybody has a machinist handbook and most of you will think this as a lame question but does anyone know of a downloadable and easy to use threading guide for writing cnc programs. We get into a lot of different threads but at very low quantity and trying to solve the handbook for each one can be time consuming, especially british and metric tapered threads.

Can't help with taper threads, but I made a tap drill calculator for english and metric cut and form taps. If anyone has a formula for taper taps or STI (helicoil) taps, let me know and I'll incorporate it.

I have a very inexpensive program that gives you everything you'll need for programming over 1100 thread sizes. It covers a lot of metric threads, but nothing for metric tapered types (yet).
