Historically, vibration–based condition indicators from employed component monitoring equipment are derived from both temporal and spectral domain analysis. However, these indicators failed to accurately capture high order correlations for the gearbox study addressed in this paper. An improved approach is necessary to overcome limitations of traditional vibrational monitoring techniques. The proposed condition indicator is derived from the Morlet continuous wavelet .transform The power spectra obtained from the wavelet transform coefficients at a certain scale or frequency are added together and then are normalised to one composite signal, denoted by a numeric index. Concepts of the wavelet index are discussed. This index is applied using real–world vibration data from a tail rotor gearbox with an output seal leak as part of condition–based maintenance practices. Results demonstrate potential of the proposed wavelet index to more effectively capture the fault when compared to gearbox condition indicators.

Due to their twisted feature, the application of flank milling to these blades would inevitably cause significant interference between the cutter edge and the machined surfaces. In view of the advantages of flank milling operations, this paper proposes a combined approach to flank milling these blade surfaces with acceptable precision and fairly high efficiency. Centring on the minimisation of the interference, the non–developable blade surface is divided into a number of strips, the cutter profile is modified accordingly, and then the tool paths are calculated strip by strip. Along with the basic idea, related issues are investigated in detail focusing on the strip width determination, cutter profile modification, and cutter location calculation. For practical use of the proposed approach, necessary algorithms are also provided. Finally, a case study is presented, together with numerical simulation of the cutting process. The results show that the proposed approach is not only feasible but also much more efficient than the conventional point milling method.

Important process parameters include the tool rpm, travel speed, tool dimensions and the downward force on the tool. Heating is caused by rubbing of the tool faces against the workpiece and by visco–plastic dissipation of mechanical energy. There is a unique combination of shear and normal forces in FSW. In this present study gaps of FSW were determined and two very much important process parameters effect on FSW (i.e., tool plunging force and shoulder size) was presented. This study investigates the effect of tool plunging force and tool shoulder size on heat generation of FSW by using 3–D finite element (FE) transient thermal analysis. It was noticed that both plunging force and shoulder diameter have considerable effect on FSW process. Suitable correlations have been made between shoulder diameter vs. peak temperature and tool plunging force vs. peak temperature. Also generalised optimum parameters were established by considering the above said parameters. The present developed FE model results were well matched with experimental results.

In this paper, Mamdani-based fuzzy logic (FL) controller has been developed to predict the quality of the parts produced using plastic injection moulding machine. It is to be noted that the quality of the parts produced depends on various geometrical requirements, such as global warpage, lower edge surface planarity and hole circularity of the manufactured part. However, these geometrical requirements depend on various input process parameters, namely melting temperature, mould temperature, packing time and packing pressure. As the input-output relationship of the injection moulding process is highly non-linear, FL technique is considered to model the process. It is important to note that the performance of the FL system depends on its knowledge base (that is, rule base and database) developed by the human expertise. In the present paper, genetic algorithm (GA) is used to optimise the optimal knowledge base of the FL system. Further, the prediction accuracy of the developed models has been tested with the help of 20 test cases and found reasonably good accuracy.","PeriodicalId":154059,"journal":{"name":"Int. J. Manuf.
