Heat Error Modeling Methods of CNC Machine ...

According to special accuracy require of mounting holes and slots of wooden door hardware, the principle of CNC processing of mounting holes and slots of wooden door hardware was put forward. Heat error is an important factor of processing accuracy of machine tools. The way of improving machine tool s accuracy by using thermal deformation compensation is a necessary intelligent module of high quality CNC machine tool s. The heat error modeling principle and methods based on genetic algorithms for processing of mounting holes and slots of wooden door hardware on the CNC machine tool were raised, which are the key for compensating heat error. The most optimized heat error can be obtained by error modeling based on genetic algorithms, which c an compensating the heat error of machine tools fo r processing of mounting holes and slots of wooden door hardware
