We have auto measuring machine for checking the cranshaft diameters. the machine is PLC programmed & checking done by digitela micrometers by robots.
kindly tell me the procedure for checking gauge R&R.
as per my view--in above case Av will become zero. so the R&R =EV but is Pv is considered as measured parts varitaion then it is also coming very less(towards zero). so the TV value is almost getting equal to R&R. so when u are are calculating gauge %R&R/TV it tends to 100% which is not good.
but if the Pv is considered as full tolerance of the component dimension. then it satisfies the below 10% condition for %R&R/TV value.
pl tell me right procedure.
