Abstract
This paper presents an Android-based system for assisting manual machine tool machining. We developed some programs used on the PC for reading data from DXF (Drawing Exchange Format) files with C# language. These programs extracted the data from DXF files, formed custom EXF files and uploaded these files to the file server. The EXF format files were used as data source for an Android application. This application got files from the file server and displayed two dimensional engineering drawings by using OpenGL ES. Meanwhile, it was connected with the digital display device of the grating scale through Bluetooth in order to realize the real-time tracking of tool path and improve machining efficiency. Experiments proved this system can accurately display coordinates of the tool in real time and improve machining efficiency.
