On-line Cutting Quality Recognition in Milling Using a Radical Basis Function Neural Network

Tool wear, chatter vibration, chip breaking and built-up edge are main phenomena to be monitored in modern manufacturing processes, which are considered as important factors to the quality of products.They are closely related to the cutting parameters, which are to be selected in manufacturing process.However, it is very difficult to measure directly the cutting quality based on on-line monitoring.In this study, the relationship between the cutting parameters and cutting quality is analyzed.A Radical Basis Function (RBF) neural network based on-line quality recognition scheme is also presented, which monitors the level of surface roughness.The experimental results reveal that the RBF neural network has a high prediction success rate.

Elementary Investigation of Increasing Polarization Performance of Air Electrode for CO2 Transfer

Air electrodes are the key components of Electrochemical carbon dioxide concentrating(EDC) cells. Therefore, the improvement of the polarization performance is beneficial to the increasing of CO2 transfer and cell stability .The preparing process of air electrode is improved by means of the pretreatment of active carbon(AC) and the selection of preparing method of platinum/carbon(Pt/C) powders. Besides, based on the analysis of orthogonal test results, the optimum preparing conditions of Pt/C powders in air electrode are achieved, that is, hydrazine hydrate concentration is 5%～10%, platinum capacity is 8mg/cm2, chloroplatinic acid concentration is 10.0mg/ml and water both temperature is 40℃.
