Abstract: In the past years parallel machine tools (PMTs) have drawn more and more interest for the advantages of high rigidity, low cost, high accuracy, high velocity and high acceleration. Parallel machine tool prototype design includes conceptual design, kinematic detail design, dynamic design, etc. The conceptual design is an iterative, complex, decision-making and creative process. Conceptual design mostly focuses on parallel manipulators enumeration in current research. The purpose of this paper is to provide a computer-aided conceptual design approach for parallel machine tool design. Firstly the design procedure and system architecture framework of parallel machine tool is proposed. Then a virtual conceptual design method is put forward which includes three steps: ①Design requirement specification. ②Motion dispatching. ③Parallel mechanism and other mechanism configuration design. ④3D modeling and simulation. The conceptual design software park for PMT is developed by UG development with Visual C++. The whole virtual conceptual design process and essential technique are illustrated by examples.
