Solidworks all the way here (contains DWG editer which is just like autocad )
Thread: Parallelism.

I`d leave well enough alone at that setting 4 microns is precise enough for all but the toughest of tolerances even a modern cnc would find that tough to beat

Thread: Parting off on Myford lathes
18/02/2011 16:27:31
Again i still don`t understand guys If as you say the chuck jaws are bell mouthed surely i would get the same chatter in both forwards and reverse setup ( this is certainly not the case as there is a difference of night and day in my forward and reverse setups for parting )

seems to me at least that the belts cannot be an issue if the lathe will part better with rear tool post or in my case running in reverse with parting blade mounted upside down .
 
surely in this fashion all saddle forces are reversed ie. instead of pushing down on the ways of the bed, cross slide , compound slide parting conventionally we are now pulling up on the ways trying to lift the tool off the machine as it were . perhaps this method works because in tension the slides tighten up on any tapered ways wereas conventional parting pushes these tapers apart allowing them to move freely due to any minute amounts of play ? any thoughts guys
