This ME Consultant program, with free, quite usable demo, is available from:
You choose the metal and operation, defaults appear and you can change work diameter, feed rate, max RPM for your machine, etc. Even the required horsepower is shown giving you an idea of what your machine can (in theory) handle.
You can also edit the material table and add your own or modify others. It also has threads and other good stuff. Den
