Abstract
Flatness testing machinery and equipment is one of the regular maintenance of the parts to the shape of tolerance testing. Since the use of quasi-traditional instrument, level instrument, electronic instrument and a model for the level of ruler to measure the parts, such as flatness, low efficiency and a larger error. Laser Tracker or the Tracker can measure the magnetic field of arbitrary direction of any error of flatness, its accuracy can fully meet the needs of the relatively high prices for higher environmental requirements, and complicated to operate.
Simplify the system as far as possible, the above two questions. Due to special circumstances in some of the precision used in small parts of its flatness error of demanding small parts for this particular error of flatness measurement, made using high-precision eddy current displacement sensor, automatic multi-point for small parts of the plane measurement, the use of genetic algorithms for data processing, resulting in small parts of the flatness error.
