The virtual noncircular gear grinding NC machine tool is set up in VERICUT.Based on the principle of noncircular gear grinding by forming grinder

the movement data is calculated and G-code is compiled.The machine tool model is built up in VERICUT

the qualified controller is choosed and the corresponding parameters is set.The simulation of noncircular gear grinding is carried out in VERICUT

and detailed analysis and discussion of the interference of virtual machining is given

and solutions is provied to these problems.Through this virtual machine tool

the correctness of the theory of noncircular gear grinding is verified and a reliable basis is provied for the actual machining.
