  • Optimum process parameters for efficient and quality thin wall machining
           using firefly algorithm
    • Authors: Akash Dutta, Argha Das, Shrikrishna N. Joshi
      Pages: 3 - 22
      Abstract: The manufacturing requirements of the aerospace industry makes it imperative to use thin wall machining techniques to machine parts that would otherwise have to be assembled from a number of parts. To achieve high productivity, there must be increase in material removal rate, which is constrained by the geometrical accuracy and surface finish requirements. Thus, a compromise must be made between productivity and product quality. This paper presents an optimisation scheme to improve the productivity while keeping the surface finish within acceptable limits during thin-wall machining operations. Initially full factorial experiments were carried out on machining of closed thin walled pocket by varying feed, cutting speed and tool diameter. Surface roughness and material removal values for all experiments were recorded. Analysis of variance was carried out to find out the most significant process parameter. Later firefly algorithm, a nature inspired swarm optimisation technique was employed to obtain the optimum process parameters for desired performance. A confirmation experiment was carried out which indicates an error of 1.27% and 1.03% between predicted and experimental results of surface roughness and material removal rate respectively.

  • Fundamental characteristics of material removal and surface formation in
           diamond turning of porous carbon
    • Authors: Mehdi Heidari, Jiwang Yan
      Pages: 23 - 41
      Abstract: Porous carbon is an important material for manufacturing ultraprecision air bearings. This paper investigates the material removal mechanism and surface quality of porous carbon in diamond turning process. A total of 32 diamond turning tests were performed and the effects of feed rate, depth of cut, cutting speed, and tool rake angle were investigated. Scanning electron microscopy of the machined surface showed that three types of material removal mechanisms occurred in the diamond turning process, which was influenced by experimental conditions. Analysis of variance of experimental data demonstrated that feed rate had the most dominant effect on surface roughness, followed by depth of cut, whereas cutting speed has little effect. Tool rake angle effects material removal behaviour in a different way from that of diamond turning of other brittle materials, showing that a negative rake angle is disadvantageous. The results also indicated that by controlling the machining conditions, surface roughness, core roughness and the bearing area curve of the machined surface were controllable, and there was a 25% decrease in the percentage of porosity after machining. It was demonstrated that diamond turning can be used as an efficient method to fabricate high-precision surfaces on porous carbon for air bearing applications.

  • A study on curved surface laser ablation using beam profile approach
    • Authors: Vivek Garg, Deepak Marla, Suhas S. Joshi
      Pages: 42 - 56
      Abstract: Laser ablation process was used to generate micro-scale curved surfaces that find applications such as micro-lens and hydrophobic surfaces. Curved surface laser ablation to produce micro-scale features generally involves altering the spatial beam profiles using masks with varying spatial opacity. The surface profile obtained mainly depends on the altered laser beam profile. This work aimed at understanding the influence of laser beam profile on the generated surface in curved surface laser ablation. The study was based on a 2D finite element model of laser ablation that considered target heating, heat transfer and vaporisation on a poly methyl methacrylate (PMMA) target. Using this model, surface profile was predicted for various profiles of laser intensity and a qualitative analysis of curved surface profiles was carried out. The quantitative comparison of the ablation depths for uniform beam was used to validate the numerical model. The results of ablation depth were found to be in good agreement with that of the experiments.

  • Weld speed effects on quality of Ti/Al dissimilar metal joints using
           laser beam welding
    • Authors: K. Kalaiselvan, A. Elango, N.M. Nagarajan
      Pages: 57 - 66
      Abstract: Laser beam welding produces good quality welds with minimum shrinkage for sheet metal joints. The quality of welded joint depends upon surface morphology, hardness, mixing of liquid phases and metallurgical non-homogeneity induced by gradients of temperatures and cooling rate at the weld interface. In the present investigation, Titanium Grade5 (Ti) and AA2024 (Al) alloy dissimilar sheet metals are joined using Nd:YAG pulsed laser beam and the effect of welding speed on crack tendencies, the strength of weldment based on hardness and composition changes are studied. Test results reveal that higher welding speed eliminates cracks in weldment and improves surface morphology. From hardness test, it is observed that the strength of fusion zone is considerably improved at higher weld speed and the findings are supported by SEM and EDS studies.

  • Optimisation of honing process parameters for reducing surface roughness
           and power consumption on grey cast iron (FG-260I)

      Abstract: Optimisation of cylinder liner surface characteristics is being done in honing process for (FG-260I) grey cast iron. Response surface methodology (RSM) and design of experiment (L54) has been used with six input variables to conduct the experiments. The parameters influencing the surface finish and corresponding power consumptions were selected on the basis of available extent literature. Second order RSM approach has been applied to develop a suitable model in honing process having six inputs and single output parameters (R<SUB align="right">a). The significant effect of input parameters on surface roughness with corresponding power consumptions has been analysed using combined effort of RSM modelling and analysis of variance (ANOVA). The RSM modelling for the honing process on FG-260I gives significant correlation coefficient (R<SUP align="right">2</SUP>) of 96.7% and adjusted correlation coefficient (R<SUB align="right">adj)2 96.5 %. The minimum surface roughness has been found by optimal parametric combinations using root mean square error (RMSE) approach. The optimised process parameters will yield acceptable surface finish at least power consumption.

  • Building without melting: a short review of friction-based
           additive manufacturing techniques
    • Authors: Sivanesh Palanivel, Rajiv S. Mishra
      Pages: 82 - 103
      Abstract: Fusion additive technologies have pushed the boundaries beyond what was previously envisaged in the metal community. Championed by laser-based and electron beam technologies, metal additive manufacturing has captivated the interests of aerospace, defence, energy, automotive, and medical sectors. Though game-changing, these fusion-based techniques suffer from solidification related issues which play a critical role in applications where high premium is placed on materials' performance. Furthermore, only limited number of alloys can be built due to complexities associated with melting. To address these drawbacks, parallel work on solid state technologies was initiated in the last decade. An outcome of these efforts has been the development of additive manufacturing technologies based on friction which has now reached a stage where compilation is possible. In this article, fundamental principle and features of these friction-based additive technologies are reviewed with special emphasis on their individual advantages and differences between them. In addition, further scope, challenges and potential of these technologies are highlighted.

  • Femtosecond laser micromachining of zirconia green bodies
    • Authors: Hyesung Shin, Wonjong Jeong, Youngsam Kwon, Dongsik Kim
      Pages: 104 - 117
      Abstract: In this study, we developed micromachining processes using a femtosecond Ti: sapphire laser for zirconia green bodies, i.e., composites comprising zirconia particles and polymer binders. The laser ablation characteristics of the zirconia composites were analysed to optimise the process. In comparison with bulk zirconia, ablation of the zirconia green bodies occurred at lower fluences. In the high-fluence regime, laser irradiation directly ablated the zirconia particles, causing aggregation of resolidified particles. The ablated depth increased with fluence (F) and overlap number (N) initially, but saturated when F and N became larger. Microchannels with a minimum width of 4 µm were fabricated. The microchannel width decreased with decreasing fluence and overlap number. Microholes, microchannels and three-dimensional structures with a size of several tens of micrometres and aspect ratio of 5-15 were successfully fabricated using the zirconia composite.
