Another example is that when using a coordinate method on the tool microscope to measure the tooth shape error, due to the coordinate position error of the standard tooth shape and the actual tooth shape, the tooth shape measuring error will be caused.

   The cause of the measuring operation causes errors

1. For example, there is an error in the focus operation during the measurement of a tool microscope, resulting in unclear images. When adjusting the position of the tooth of the milling cutter, the tooth profile image does not reach the zero definition, causing the measurement error.

(Effect of error on tools)

1. Another example is to measure on the tool microscope, use the pressure line

There is an error on time on time, resulting in errors in the horizontal reading, which causes tooth -shaped measurement errors.

2. If the measurement operation is not skilled, there is a deviation in looking for the position of the tooth outline.
