| Summary: | The article is devoted to calculation of measurement error of
contact of active control devices (ACD) of product dimensions
using artificially created corundum tips. It is shown that most
of it is determined by the temperature error that occurs due
to its thermal expansion of the tip when heated as a result of
mechanical contact with the detail. The calculations are based
on the formation in the tip of the route of the input and reflected
optical flows at an angle to its front surface providing a complete
internal reflection in the contact area with the detail.
The calculation of measurement error is made when creating
a reference channel in the laser interferometer, fixing the
displacement of the back side of the tip from its thermal
expansion. A significant reduction of measurement error for this
case is shown. |
