Abstract:According to the low measuring accuracy from a flexible coordinate measurement machine,the error correction and parameter calibration methods for the coording measarement machine were researched.An improving genetic algorithm based on optimization least square method was proposed to implement the parameter calibration.The kinematic model and the error model of the flexible coordinate measurement machine were established by Denavit-Hartenberg(DH) method.Firstly,a variable factor was used in least square meth...
Keywords:flexible coordinate measurement machine  parameter calibration  error correction  genetic algorithm  optimization
