WebThe thread milling operation is based on three-axes simultaneous movement so the profile shape on the workpiece is not a copy of the insert profile. In other words the profile is generated and not copied which is contrary to the thread turning operation. This fact causes a profile distortion, especially when machining coarse pitch internal threads.

WebNov 19, 2015 · I plan to install the RR by threading it through the 5/8"x24 UNEF threads all the way to the PCB. The problem, then, is that if I can't install the RR in its designed groove but that's not a huge issue. If I can run the RR all the way down to the bottom of the threads and leave it in a .022" thread relief it will be plenty strong and hold the PCB. WebMay 5, 2006 · I thought I could do this in just one equation where the thread relief formula would equal whatever the major diameter is of the thread. For the thread relief dimension needs to equate 1.5 threads. That answer will vary depending on what size thread I use. Hope all this makes sense. If I need to clairify please let me know.
