I am asked to deduce from these lines of code the angle (per side) of the taper being machined. The tnr is .031. I am also given the selection of 30, 25, 45, or 63 degrees. Can anyone show me how this is done?? If this is the wrong forum for this type of question, please forgive me and kindly forward me to the proper one. Thanks.
