The Meaning of Probe Calibration in XY

[mayu]

By definition is calibration in XY really the difference between the true center of the ring gauge and the center of the probing points when running a calibration macro? That difference is then stored in the system variables, and our macros use those values to compensate their probing point positions?

[Leon82]

Yes.

 

It's taking actual stylus diameter and lag time between the probe strike and the triggering of the skip signal.

 

But but you have data for x minus x plus y minus y plus and vector angles

For the lag time is it #3001 time information variable that is being utilized? In what variables are the actual differences stored in, both for the lag time and the positional differences?

[cncappsjames]

It's not really lag "time", it's lag distance. #502 and #503 for X and Y non vector calibration respectively and #510-#518 for probe radius trigger points on vector calibration.

So if a ring gauge location is X100. Y100. in the MCS, and the probe calibration results in X100.05 Y100.05, the macro stores .05 in both #502 and #503?

That's it - that's the calibration?

Every machine here  has their own individual program based on the machine position of our gage fixture which is mounted on pallet a.
