Greetings; I'm in the process of making yet another encoder disk for the lathe as I fine tune the code to get the correct width(duty cycle) of the slots, and making the center hole a couple thou bigger as it turns out the high spot corresponds to the peak of the thread where it is sitting on the spindle shaft trapped between the two bearing nuts.
But it occurs to me that this code is dig cutting, meaning the bit as it dulls, will skid rather than shave at first contact and be pushed farther and farther off the line until it snaps. That seems like it would equal narrower than programmed slots long before it snaps off. IMO, climb cutting would eliminate much of that as the cutting edge would be straight at the point of first contact, cutting a clean, tapering to zero thickness chip. So I am inclined to do a bit more editing and re-arrange the move order for the individual slot such that it will be climb cutting, aka chopping into the leading edge. That, combined with a fresh mill would seem to me as being the preferred method for precision work. Right? Wrong? Thanks.
