CNC automatic programming design method and system and computer storage medium thereof

The invention relates to the technical field of intelligent mold design and manufacturing, in particular to a CNC automatic programming design method and system and a computer storage medium of the CNC automatic programming design method and system. Performing UG execution; performing background execution; drawing file names are double-clicked; obtaining interface data and drawing file data; the serialized data are sent to the background execution end and the NX execution end; the NX external mode client unit and the NX internal mode client unit receive data respectively; performing deserialization on the received data; an NX external mode is adopted to execute related functions; executing a corresponding function by adopting an NX internal mode; the execution completion data is returned to the interface. The technical problems that in the prior art, an existing CNC automatic programming design mode is limited in machining cycle shortening capacity and low in working efficiency are solved, the machining cycle
