Making use of function of NC programme provided by Pro/NC, aiming at general NC milling machine and using general milling cutter, this thesis attempts to establish the tool path of straight bevel gear’s finishing machining and then put forward the idea of processing piece by piece. In this way, “over cutting” and “short cutting” can be avoided and the precision of process can be improved. Finally, the accuracy of product designing and manufacture can be tested by post-processing of numerical control program of straight bevel gear’s finishing processing with the VERICUT’s simulating.

To develop the numerical control program of mill-turn machine, the traditional method is to apply the computer-aided design and manufacture software to construct the geometric model, then to generate tool path and convert the path to NC program. For complex numerical control program of mill-turn machine, such as the multiple turret synchronized motion machining, because of the need to control time sequence, the NC program is highly required on using of dedicated software system. The objective of this paper is to establish a mill-turn machining system with window interface of via the language of Borland C++ Builder. The developed system can plan the machining path of simple mill-turn features, including turning shape, axial slot milling, and radial packet milling, and generate the corresponding NC program. For the milling functions, after the offset coordinates are calculated along the polygonal angle vector in the center point of cutters, the NC program is generated. For the turning functions, through importing the 2D DXF (Drawing Exchange Format) file and inputting related configurations, the entity coordinates can be retrieved and the corresponding NC program is then converted. By means of the solid cutting simulation software and practical cutting experiment for the generated numerical control program, the accuracy of the tool path generation algorithm is confirmed. Hence, the cost of purchasing commercial software can be saved and the time of generating program can also be decreased so that the working efficiency can be enhanced.

CAM software is generally used to generate tool paths for 5-axis controlled machining. However, adjusting its several parameters and settings is difficult. We propose a system for tool path generation to be applied to 5-axis controlled machining. The system allows machining movements to be established by manipulating haptic devices in a virtual environment. Therefore, the cutter location for 5-axis machining can be easily controlled by operating a virtual cutting tool. The contact between the cutting tool and the target shape is reflected to the user through the haptic device. The generated path can be converted into a numerical control program for the actual machining of the target object. We detail the implementation of the proposed interface using two haptic devices and a method of tool path generation that improves rough cutting by smoothing the generated cutting points and simplifying the tool postures. The effectiveness of the developed system is confirmed through machining simulations.

Manufacturing industries such as the aerospace industry and the molding industry need to process products of complex and high-precision curved surface. Multi-axis machine tool with two rotational axes plays an indispensable role in processing such products. However, in a fiercely competitive market, each manufacturer is devoted to reduce processing time and costs. Therefore, how to efficiently create multi-axis numerical control program has become an important issue. Typical multi-axis machining parts often have specific machining features such as hole, groove or even engraved text on the inclined plane. Although the tool path can be generated by the advanced multi-axis CAD/CAM system, the prices of such systems are very high. This study proposed a methodology for defining the inclined working plane of the multi-axis machining tool. According to the defined working coordinate system proposed in this study, the tool path files of the traditional three-axis machine tool can be transformed to the five-axis NC program through post-processing calculation. As a result, the required NC program can be obtained for the same machining feature on any inclined plane in shorter time. Finally, this study tested and confirmed the accuracy of the numerical control program by solid cutting simulation software.

Computer Numerical Control Machines (CNC) totally changed the scenario in manufacturing industries in terms of production volume, easy flexibility and with fewer deviations.    As customers expect high grade of accuracy, precision, reliable and prompt supply it became essential in the manufacturing sector to reduce the time for developing and proving out new products. Normally programming and proving out the same plays a significant role in the product development cycle. Nowadays several software packages are there to stimulate the tool path, sequence of operations and validation of the program to ensure flawless performance. These packages do serve additional role of optimizing the program sequence and reduce the cycle time involved to manufacture the parts concerned.

The tool trace of turning is intensive and complex, and its virtual manufacturing with high confidence level needs to be solved urgently. In response to this pressing need, based on the general mathematical model of master-slave alignment for shaft part profiles, efficient and low-redundancy "dynamic grid" for data structure and "tool driving" exact algorithm for cutting path, the paper built a database that was flexible to adapt the data structure, packaged an Open Graphics Library (OpenGL) to form the automatic three-dimensional engine, and developed a three-dimensional virtual manufacturing system with high confidence level for turning, with numerical control code analysis, error correction, tool path simulation of turning process, parts management, all-round display, virtual manufacturing process control and other functions.

The realization of the handwheel function is a key problem for development of numerical control system of micro milling machine. This paper introduced the interface specifications and hardware connecting methods of handwheel NK100AB2, developed control program based on PMAC (Programmable Multi-Axis Controller) and industrial personal computer, finally achieved the function of axes selecting and the feed rate selecting. Based on the traditional edge detector tool setting method, an improved tool setting method is proposed. The inverted micro milling cutter hilt is used to replace the traditional edge detector, which avoids the opposite reamer error caused by the irregular cutter blade shape, finally, tool setting function is achieved through the collecting of electrical signal. The research will provide a useful reference for the realization of handwheel and tool setting of micro milling machine based on PMAC.

Standard for Exchange of Product Model Data (STEP) is a Standard associated with representation of product data model to enable data communication between different Computer-aided Design (CAD), Computer-aided Manufacturing (CAM) and other engineering systems without any ambiguities and any possible data losses. The development of Open Architecture (PC-based) Numerical Control (OAPC-NC) Interpolator has enhanced the possibilities of data communication between the systems. A tool path data interface to OAPC-NC interpolator is proposed and developed; and a hierarchical-based algorithm is used to extract the tool path data from STEP-NC tool path file of a product model. The generated output of the interpolated data is computer simulated for 3D straight-line path to verify the validity of the interpolator input generated by the proposed interface.
