The tool nose of the CNC tool has two forms of optical and photoelectric alarm aiming, and the aiming precision is high. It is equipped with a microcomputer system for tool measurement, data display and print storage. It can also directly communicate with the CNC system of the CNC machine tool and the machining center host to realize the online function. The tool pre-adjustment measuring instrument or the tool setting instrument has a two-dimensional coordinate measuring system. In order to directly measure the vector error of each point in the instrument space, the instrument is error-compensated, and the workload is very large. In order to simplify the error measurement work, the instrument is first simplified to a certain physical model. Then, the model derives the exact relationship between the spatial point position error and the instrument mechanism error source. When the position coordinate value displayed by the instrument is X and Z, the corresponding point position error value $X, $ is obtained from the relationship. Z, after error compensation, the exact position coordinate values ​​are Xc, Zc, where: Xc=X+$XZc=Z+$Z. The influence of force deformation on the instrument error: For the instrument with cantilever structure like the tool presetter, due to the structural characteristics of the instrument itself, the instrument has deflection deformation and cross section under the self-weight of the photoelectric sight and the beam. Corner deformation. Its deformation is mainly affected by the following three aspects: 1 The self-weight of the photoelectric sight is equivalent to adding a concentrated load P at the end of the beam. The load P will cause the beam to have a deflection ZP and a section angle HP at the end points. 2 The self-weight of the beam will produce a uniform load q so that the deflection Zq and the section angle Hq are also generated at the end of the beam. 3 The force column is affected by the bending moment MA, so that the sinking amount ZA and the corner HA are generated at the end of the beam. Obviously, the total deflection at the end of the beam is Z=Zp+Zq+ZA, and the total section angle is deformed by H=Hp+Hq+HA. These two deformations are affected by the position of the beam and column and are a function of the position of the beam and column. The additional displacement X(x,z) in the X direction and the additional displacement Z(x,z) in the Z direction produced by the deformation are both binary functions of X and Z.
