In the 1988/1989 timeframe I ran a Mori Seiki (SL25?) with a Fanuc control. I built a tool holder to hold 3 tools on one tool station on the turret. I had a spot drill, drill and small boring bar mounted. The tools could be varied as I used small round shank collet holders. Ex. T0101 would be tool station 1 offset 1 This would spot drill and move back (Z positive to a clearance point)
T0111 would be tool station 1 offset 11 This would (without the turret rotating) drill the hole and move back (Z positive to a clearance point) T0121 would be tool station 1 offset 21 This would (without the turret rotating) bore the hole and move back (Z positive to a clearance point) \Ex. One lathe I ran (I wish I could remember what the control was) would allow me to change the value of the offset while the control was running. The offset change would be applied (interpolated) during the running of the next block of code. The control would read the offset value at the beginning of every line of code and interpolate to the end point while applying the offset value. I thought this a very useful feature. Never saw it again. Most of the controls I ran have had wear offsets available. I never used them. I thought they were confusing and just one more opportunity for human error and forgetfulness (maybe this is just my way of self protection/compensation). I probably would not use wear offsets today. I don't see the point.
