Greetings all; I am attempting to rewrite yet again, the G33.1 code driver to do this tapered threading, either on the OD or the ID, emphasis on the ID ATM.
I know that the taper angle is 7 degrees I have converted all the inputs that were inches into mm's so I have a common base numbering system. And I know the threads length is 14.9mm's from start of the G33.1 motion to the end. So, I will also work with the equ of a 1.0 in the thread depth which is as deep as I can cut at the inner start, and back inward for retrace clearance without running into the back side of the hole with the tool retraction. And that the thread depth is nominally .866 times the height/depth of the thread. And that each thread at 27 tpi advances z by 0.940740741mm's. What I don't seem to get is the method of determining the ending X radius, and how to arrive at both the new x as the threads are cut ever deeper This latter x start, ending at x-taper seems like simple addition. If that is accompanied by a Z starting increment that is added to both Z start, and z end, it looks like adding or subtracting from both z_start and z_end by the pass number, at which point I get lost in a sea of variables trying to get that magic 30 degree angle where all the cutting is done on the front edge of the tooth. in other words do the taper exclusively with X, and the 30 degree angle as x is advanced, by adjusting both ends of the z travel Can I find simulated code for that anyplace on the innertubes? ====== $40.16 + local taxes will get me bearings for both of those motors. Playing with the inverter settings, I have made those motor's reverse hard enough to make them jump off the table a fraction of an inch in under a second. But by the time they've set back down they are just a few milliseconds from doing the same speed in reverse. So I don't think I'll have a bit of trouble running them with LCNC. Unscrewing the screw on chuck will be a bigger problem. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
