I have a question regarding the usage of test indicator for measurment.I already know the answer,but would like some feed back from other metrologists.I work for a small company in canada,we make mold parts mostly for Husky.the usage of test indicators is rampant here at this facilty.tolerances are .005 microns total or .0002 inch.remember I said test indicator not dial indicator.Most employees use these the wrong way ,but the owners of the company do not realize how small 5 microns is(they are also managing the place)cosine error is rampant but i can't seem to get thru to them.Angle correction factor for the tip is never implemented.Most are measuring the underside of a shoulder 10mm +.005 with the tip almost vertical.Any articles or info that anyone could share would be great.Our
