Abstract
The main purpose of this project is to develop a low cost, effective, user friendly interface software for staff and students to integrate the designing and manufacturing facilities in the Institute of Technology and Engineering (ITE) at Massey University, Palmerston North, New Zealand. The project involves establishment of an integrated CAD/CAM/CAE system, the identification of software requirements, selection of software development tool kit, definition of hardware configuration, software development and final experiments and tests. ITE has a laboratory, where are equipped with one CNC milling machine, one CNC lathe, one Injection Moulding machine, one desktop 3D scanner and one 3D plotter. In addition, all the CAD/CAM/CAE software have been installed on the PCs. Based on the analysis and utilisation of these existing facilities, it is found that they are not smoothly integrated; no linkage between the CAD/CAM/CAE system and desktop Rapid Prototyping facilities; file formats used by each of the system are not compatible. Through this project, the investigation of the possibility to integrate the system and the feasibility to develop a software to bridge the 3D scanner and the CNC mill, was carried out. A first try was successfully made using Borland C++5.0 to convert the 3D scanned data into NC program. Then, using Borland C++ Builder 5.0 created a user-friendly interface for conversion of 3D Digitizer to CNC Mill. Next, the different scales of wax models were satisfactorily processed on the CNC milling machine by inputting the converted NC program.
