Realization of Automatic Programming and Machining Simulation System of NC WEDM Based on VC
WEDM(wire electrical discharge machining)is an important part of non-traditional machining,which is widely applied in aerospace part-processing.In order to solve the problems of complicating operation and defective drawing func-tions of automatic programming system of WEDM machine,through in-depth analysis of WEDM process,one simple and clear project of auto-program and simulation is put forward.The system framework and each function module are con-formed,including each function module interface.Meanwhile,the COM technology and dynamic link library(DLL)are used to realize part graphic input.Then,NC code simulation is implemented by ActiveX,and the whole support database is set by Access.Finally,AutoCAD graphic input is realized in the interactive environment,including the content of calculating cut-ter locus,generating post-processing documents and achieving all the NC code animation simulation.The work above highly improved the success rate one time of WEDM,also meet the needs of actual processing.
