I am new to the "Quality" environment so maybe someone can shed some light for me....I was recently sent a 5ft caliper to measure vinyl cut parts...sizes and style vary....why?? I was told because our tolerances our +/-1/32, our tape measures are not accurate because the operator may have to judge between whether the length is nominal or off by a 1/32, if it is between they feel that everyone rounds it down to the nominal and feels the process is not in control. I don't understand how a 5 ft. caliper will be more accurate??? It seems to be alot of money spent on a possible 1/64th difference. Any comments???
