The existing sheet metal dieless forming technology has the problems of high device cost and the needed support not easy to be manufactured.To slove the problems,a method is proposed to realize the sheet metal dieless forming based on CNC machine tool and the related techniques such as forming fixture design,support manufacturing and forming tool path generation.A forming experiment has been done to verify the practicability of the method.
