Abstract: NC code to machine arc-surface of the transmission box had been obtained in UG CAM module. Then, the code was imported into Vericut in order to control the virtual machine to mill the box’s arc-surface. As a result, the simulation process machining the typical arc-surface of the transmission box was achieved. Meanwhile, the collision and interference were all verified as well. The accuracy of NC code was not only tested but also modified in this process. Due to this work has been finished, the production cost will be decreased and the production cycle will be shortened. It is of great guiding significance for the actual production process.

Abstract: In this paper, a method of automatic NC code programming is studied. The data structure used to store graph information is the base of automatic programming system. By utilizing the object-oriented tree data structure proposed in the paper, the disadvantages of the method caused by using simple data structures can be overcome. In processing information, the judgment of topological relationship between two outlines is very important. The Loop Extremum Method is easy, convenient and with no limitations. The system adds plenty of technological parameters, provides multiple machining patterns. In the end, an example is given to test and verify the system`s functions.

Abstract: Programming of graphical interaction and modular structure are adopted in this wire cutting machine software by analyzing the structure of DXF file, picking out the part’s outline information in Visual C++ 6.0, and combining the manufacture conditions in this paper. The NC codes are obtained which are consistent with the high-speed cutting machine processing system automatically. This system software greatly facilitates the process of high speed cutting machine, shortens programming time and improves the accuracy of the programming.

Abstract: This paper presents a new simulation system for ultra-precision diamond turning of optical free-form surfaces based on fast tool servo (FTS). The functions including evaluation and analysis of optical free-form surfaces manufacturing errors, optimization for tool path, etc, are proposed. The simulation modules and functional structure of the system are designed in accordance with the functions. The errors in the process of machining can be found in advance through the simulation. Then the NC code will be modified timely. The proposed method can be used to improve product quality, shorten the development cycle, reduce costs and optimize machining process.
