Hi Steve, Here's my take on G76:
> I don't understand the implementation method, in particular the "drive > line" mentioned in the manual. The drive line is the safe clearance outside the thread. It is the current X axis position when you call G76. I normally use thread peak + 1mm. I is the distance from the drive line to the thread peak K is the distance from the thread peak to the thread root (cut depth) > Was that program written for radius mode? Undoubtedly. Diameter mode is pretty recent. > > Wouldn't a XZ start point and an XZ end point and a return clearance > distance have been more practical? And less confusing. G76 gets the job done for parallel threads but you do have to really think about it. > > It would appear from the parameters that the G76 doesn't support taper > threads. No it doesn't. I had to do a taper thread today and the only way was with G33.
