Abstract: In order to well lubricate the industrial machine and decrease the consumption of lubricating oil, it is necessary to develop a system to monitor and control the density of oil mist. This paper introduces such a system based on LPC2214 of ARM7. The system can monitor 10 parameters, give an alarm to the status of factors which affect the quality of the oil mist and store the relative information into high capacity SD card through I2C bus and SPI bus. All the status information can be shown on LCD so that the operator can realize the system in real-time. System supplies input interface which can set some parameters and display other information on LCD, including history status information of system.Keywords: LPC2214, Oil mist, SD card, LCD

Abstract: A lot of lubricating oil is consumed in the process of the cold rolling of stainless steel. The oil recovery is very important due to some reasons, such as the cost of production and environmental pollution. A set of lubricating oil recovery system is designed and constructed, which is equipped with a set of expanded size recovery oil pan for recycling splashed oil, a high efficiency two-level mist recovery system for recycling the oil mist, and an oil collection platform for recycling the oil rolled. The system is effectively to recovery more of lubricating oil through actual use and measurement.

Abstract: Large amount of cutting oil consumption is one of the issues for environment. The Minimum Quantity Lubrication (MQL) technique has been applied to the near-dry cutting process. However, MQL technique generates oil mist which is harmful to the working environment and the health of factory workers. In this study, a new lubrication system called Direct Oil Shot Lubrication System (DOS) was developed and applied to milling processes. The performances of DOS technique was evaluated by measuring the floating oil mist and carrying out the cutting tests. The amount of floating oil mist of DOS system was considerably reduced compared to the MQL. The behavior of small oil drops supplied from DOS nozzle to cutting edge was analyzed by means of a high speed video observation, and the optimum setting for DOS was obtained. The experimental result shows developed DOS system realized the smaller density of oil mist floating than the MQL technique while the DOS attained the almost same lubrication effect in milling process as the MQL technique.
