Click HERE to retrieve the part used in this exercise.
Make a round thread pattern for a 3/4" dia. rope on the O.D. of a round bar using a 1/2" dia. round insert.
15" major dia.
** 1) On the Thread Menu make sure the Major Dia. is set to 15". 2) Hi-light the Minor Dia. field and ALT+Click the point at 3 O'Clock to input it's value into the Minor Dia's. field. 3) Hi-light the starting "Z" field and ALT+Click the same point (-3.455). 4) Hi-light the ending "Z" field and ALT+Click the same point and then modify that value to represent the end of the thread (-3.455 - 7 = -10.455). 5) Subtract a 1/2" from the Minor Dia's. value to force the tool tip to the correct diameter ( Minor Dia. value - [1/4" TNR x 2].
I alternated the thread passes from leading edge to trailing edge of the thread for each dia. step in order to make balanced cuts.
