VERICUT is a three-dimensional software, which can not only perform the processing simulation but also can conduct program optimization, so that it can achieve the simulation of processing path and machine tool. This paper mainly introduced the technology of virtual machine tool, its common modeling methods and the simulation for processing path. At the same time, the modeling of machine tool is established and the simulation processing for one part is carried on by means of this virtual machine tool. The simulation can eliminate the phenomenon such as interference due to collision of tools during test cut, remove the cumbersome process of test cutting trial and effectively predict processing results. Furthermore it also can reduce the cost, improve the efficiency of programming and shorten the cycle of manufacturing. Subsequently this technology has broad application prospects in modern manufacturing.
