Tool offsets

[Handi-andi]

Hi all
I was just wondering if anyone used a 3D Taster in their CNC lathe in order to help them set up tool offsets? Having used one a lot on my Bridgeport Interact Milling machine and having regularly having had to reset the tool table on my Denford Easiturn CNC lathe it would seem like a relatively quick way to do it rather than having to turn bar stock and check diameter or touching off tool on a known diameter and risk breaking insert etc. Obviously one would nee to move back and forth along Z-axis when setting X-offset to ensure one picked up the centre of the spherical probe tip, but that's relatively painless. Interested to hear other people's thoughts on the matter
Thanks
Andy

hy handi a 3d taster is too complex for such a task

i would recomand a "zero setter"; please check the photos from here ( one uses the chuck for Z offset, and other uses the tailstock for X axis ) : https://www.cnczone.com/forums/okuma...ter-using.html

idea behind all these is to use a "zero setter" instead of the "touch setter" thus, the idea is ok when there is no touch setter, or for setups where you can not use it ( for example when having a loooong part between spindle and tailstock, that makes it impossible to use the touch setter )

there are also other faster methods : if you can grid-shift XZaxis, and offsets origin, you may do stuff like this :
... z offsets represents the distance between the tool nose and the turret face
... z program 0 represent the distance between part face and chuck face
*and so on


last but not least, if you can use system variables for offsets, you can do many little checks, turret real layout save, off-line colisions check, in machine checks, computing custom positions for indexing the turret, and other tricks / kindly
