Abstract
Although most of the 5-axis NC milling machine tool producers declare that their machine poses the function of 5-axis simultaneous machining, and most of the commercialized CAD/CAM software was reported it can support the 5-axis simultaneous machining, but there are very few analyses about their machining efficiency. I hope that the reader would be interested to know how the new method is highly effective. The paper did a good job in motivating the problem mentioned here. The model of this paper is extremely efficient ant. This is a highly effective way of surface machining. There are also some areas that need improving. The mathematic presentation is not clear, but much more pages are needed, if the authors like to make it clearer. In the resent paper “The Extreme Efficiency of the New Model in Milling of Complicated Surfaces” we discussed the extreme efficiency of the new model in milling of complicated surfaces in 5-axis machining for 2-dimensional contact. While this time let’s discuss the same problem but much complicated one, 5-axis machining for 3-dimensional contact. As the research activities conducted by Dr. Liu Huran opened a new field and wide horizons in 5-axis machining of sculptured complicated surfaces using mathematical theories, and according to the interesting results presented in paper, Dr. Liu Huran is strongly encouraged if he can submit a similar work but this time with a new title that corresponds to the purpose [1].

This paper introduces currency method of NC machining method, develops the machining efficiency and precision of NC machine, and comes to conclusion that the local contact tool path can increase machining efficiency and sweep surface of the cutting circle on close contact path can increase machining precision [3]
Summary
The small amount and high precision products provide wide application and developable perspective for 5-axis NC machine. It makes a fundamental change for NC programming [2]. This paper introduces currency method of NC machining method, develops the machining efficiency and precision of NC machine, and comes to conclusion that the local contact tool path can increase machining efficiency and sweep surface of the cutting circle on close contact path can increase machining precision [3]. This paper uses the NURB surface describing surface model, uses Boolean operation to simulate the machining process with the file of tool position and direction angle [6] [7] [8] [9]. Explanation to the Extreme Efficiency of New NC Method: the thinking Route [1]: a) The local development or the local reconfiguration of the surface on any one point; b) None vertical transformation in order to transformed into the vertical standard system; c) The condition of best machining posture in order to get highest efficiency of NC machining; d) The extremely efficient cutting method on the local point to be machined; e) The steps of calculation (take an elliptic ball for example); f) The Coordinate Transformation in order to be changed into coordinate system of the machine tool
