Application And Research Of NC Reformation For Large Lathe

In the aspect of cost,difficulty of implementation,transformation period and operation difficulty,the membership function is used to express each index as the characteristic function of the fuzzy set,which involves many kinds of schemes.BP algorithm is used to establish the mathematical model,including the number of input points,BP network nodes,the number of output,genetic algorithm parameters to determine content.Optimization of multiple programs,derived transformation program.The transformation practice verifies the reliability of the optimization of BP algorithm,improves the objective weight of the index weight,and reduces the influence of the subjective factors to provide a new idea for the optimization of the scheme.During the debugging period,the use of FANUC LADDER software to achieve ladder and CNC system parameters of the import and backup.NC program through the CF card to facilitate the transmission of information for small and medium enterprises off-line CNC machine tools and parameters of the backup and restore methods and basis.The development function of Autocad software is used to develop the Lisp program,which realizes the calculation and solution of coordinate nodes during the interactive process of human-computer interaction.The problems of multi-size and multi-dimension in NC machining process during the course of cutting rolls are efficently and precisely solved.The effect is good After the transformation,the method and experience of the process during NC reformation can be used and referd in other traditional equipmentof the technological transformation.
