It is at the beginning of the birth is mainly based on the workstation, but with the rapid growth in the development of PC hardware and individual users, its application in PC has achieved rapid growth, has e a mainstream application of three-dimensional design of mold industry. The goal of UG is to use mathematical technology, namely the local adaptive mesh refinement, multigrid and puting, provide a flexible and reusable software base for plicated practical problems. Model module using UG plete the 3D product modeling design, Manufacture module and UG for NC simulation machining and production procedure of.
