Dear Experts In a VMC with Fanuc 0i, as operator did not select the right program, spindle tool banged with fixture causing huge damage to spindle and downtime. We continue training operators to keep feedrate at 0%, check distance to go, reset if distance to go looks alarming, check work offsets & then slowly release feed, still this is not being followed. Request to suggest any other fool proof way of avoiding this Regards

Hi there, I am currently using a custom G-code on our lathe to safely call up a tool and turn on spindle, coolant etc. Here is the calling code: G800 T0101 X1.7 Z.05 S500. M8 I would like to be able to program in the tool nose radius and tool tip direction using the system variables. So based off of the tool offset value (TXXXX) in the calling G-code it could automatically set the correct tool nose radius and tool tip vector from the program. Something like this: Where V = tool tip vector R = tool nose radius G800 T0101 X1.7 Z.05 S500. M8 V3. R.032 I have considered automatically assigning a tool offset value based on the turret pos which I think I could get to work, but would like to be able to leave Turret position and offset in calling program if possible. I am not sure if there is a way to do this? Any ideas / help appreciated. Thanks
