【正文】 rcular feature ? R charts from the X bar – R charts represent the range of measurement error ? Control limits are calculated using statistics for the wrong distribution – the normal distribution 169。 2023 Bob Doering All Rights Reserved CONCLUSION ? X hi/lo – R charts represent the GDT characteristics of a circular feature: diameter and the zone represented by roundness (or length and parallelism for a linear dimension) ? X hi/lo – R charts provide more valuable data, such as tool wear rate ? X hi/lo – R charts use the correct uniform distribution for precision machining 169。 2023 Bob Doering All Rights Reserved CONCLUSION ? X hi/lo – R charting techniques can be expanded to control taper ? Automated tool wear pensation is not statistical process control ? The algorithm for pensation bees the process, not tool wear ? Lose some benefits of SPC because the constant adjustment masks the information ? Would help if the pensation was tracked 169。 2023 Bob Doering All Rights Reserved CONCLUSION The total information is given by the observed distribution.” Dr. Walter A.
