Abstract： Aiming at the limited usage of macro programs in actual CNC programming due to its relatively high risk caused by unavoidable manual programming errors，macro program for an actual milling example i.e. milling of grooves in a planar spiral way was demonstrated，logic calculation of the macro program was illustrated and simulation in Vericut was carried out. Every step of calculation in the macro program was checked and distances between machined surfaces to design model were measured. The results indicate that all steps of execution of the macro program on CNC machine can be simulated by Vericut，and the distances between machined surfaces to design model are in accordance with the setting values of R parameters in the macro program，i.e. the correctness of macro program is verified. This example indicates that by combination of macro programming and Vericut simulation，the efficiency，university and safety of CNC programs have all been improved.
