This paper is to simplify the keys on the control panel of the numerical control machine and use two keys to replace the traditional multi keys for cyclical selection of the working mode of the numerical control machine. The key signals are linked into the PLC by several signal wires on the control panel for the selection of the working mode, making the design of the panel structure and the signal circuit extremely complicated. This paper proposes the scheme in which there are only two keys "Working Mode +" and "Working Mode -" on the control panel, and works out a corresponding PLC program based on the FANUC system. The program deals with the cyclical selections of all the working modes and a quick entrance to the commonly used mode. The "Double Keys Scheme" reduces the number of keys on the panel, simplifies the control circuit, lowers the manufacturing cost, improves the stability and realizes the shortcut selection of the modes.

A general universal vertical lathe was studied in this paper which comprises two columns. The lathe can be used for roughing the cylindrical workpiece, end surface of inner hole and the inner and outer cone etc. The lathe structure and hydraulic system were improved on the basis of keeping the basic operating functions. After improvement of the lathe structure, it is more convenient for finding the exact position of the workpiece and the loading capability was improved. Meanwhile, the spindle can work smoothly and precisely. According to the improvement of the hydraulic system of the machine, the level of automation was enhanced and the working ability of the lathe was improved.

Based on the internet technology, it has become possible to complete remote monitoring and fault diagnosis for the numerical control machine. In order to capture the micro-shock signal induced by the incipient fault on the rotating parts, the resonance demodulation technology is utilized in the system. As a subsystem of the remote monitoring system, the embedded data acquisition instrument not only integrates the demodulation board but also complete the collection and preprocess of monitoring data from different machines. Furthermore, through connecting to the internet, the data can be transferred to the remote diagnosis center and data reading and writing function can be finished in the database. At the same time, the problem of the IP address floating in the dial-up of web server is solved by the dynamic DNS technology. Finally, the remote diagnosis software developed on the LabVIEW platform can analyze the monitoring data from manufacturing field. The research results have indicated that the equipment status can be monitored by the system effectively.
