In this paper, based on the analysis of the concept and connotation of virtual machining, some of its key techniques are discussed, including geometry modeling, numeric control code translation, interference detection and material removal simulation. A typical architecture of virtual machining system is presented, based on which, a virtual machining system named as General Machining Procedure Simulator (GMPS) is implemented at the national CIMS Engineering Research Center (CIMS-ERC) in Tsinghua University. Now the system has been applied to practical engineering projects and some benefits are gained., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null,
