Always wonder how other people solve the challenge on the dial test indicator measuring error,
most of the dial test indicator have their cosine error, which deviate according to the angle of the level. (level is flexible). although there is correction factor to calibrate it but how accurate we can get the level angle?
from previous experience the measuring error is even bigger then the part tolerance. this make the measuring not accurate.
on the other hand, wonder how accurate to use dial test indicator to measure a embossed polymer part ( concern on the level force will affect the embossed height).
Thousand Thanks
