  • Reliable tool life measurements in turning — an application to cutting Fluid Efficiency evaluation
    International Journal of Machine Tools & Manufacture, 2001
    Co-Authors: Dragos Axinte, Walter Belluco, Leonardo De Chiffre
    Abstract:

    Abstract The paper proposes a method to obtain reliable measurements of tool life in turning, discussing some aspects related to experimental procedure and measurement accuracy. The method (i) allows an experimental determination of the extended Taylor's equation, with a limited set of experiments and (ii) provides a basis for the quantification of tool life measurement uncertainty. The procedure was applied to cutting Fluid Efficiency evaluation. Six cutting oils, five of which formulated from vegetable basestock, were evaluated in turning. Experiments were run in a range of cutting parameters, according to a 23–1 factorial design, machining AISI 316L stainless steel with coated carbide tools. Tool life measurements were associated to an estimation of their uncertainty, and it was found that by taking three repetitions the uncertainty calculated with a coverage factor of two was on average three times bigger than the experimental standard deviation.

  • A multicriteria model for cutting Fluid evaluation
    Proceedings of the Institution of Mechanical Engineers Part B: Journal of Engineering Manufacture, 2003
    Co-Authors: Dragos Axinte, M. Axinte, J D T Tannock
    Abstract:

    AbstractThis paper describes the results of a comprehensive evaluation programme for cutting Fluid Efficiency, when machining the aerospace ‘superalloy’, Inconel 718. The machining methods used were milling, drilling, tapping and VIPER grinding. Results from three cutting Fluids were evaluated: a water-based semi-synthetic, a water-based synthetic and a high-oil emulsion Fluid. Cutting forces, torque and spindle power were acquired during machining, while geometrical accuracy, surface texture and surface integrity of the workpiece were analysed afterwards. The experimental results demonstrate the difficulty of identifying the ‘best’ cutting Fluid, especially when several different machining methods are to be employed on the same machine tool. It is unlikely that a single Fluid will show the best performance on all machining trials and output measures. Therefore, prioritization of the output measures and specification of the relative importance of each machining operation becomes essential, in order to eva...

  • communicative Efficiency and miscommunication the costs and benefits of variable language production
    Cognitive Science, 2015
    Co-Authors: Alexandra Paxton, Jennifer M Roche, Michael K Tanenhaus
    Abstract:

    Although negotiating joint action through dialogue can be difficult, dyads may be able to improve collaborative performance by managing communicative Efficiency in language production, balancing effort (words per turn) with output (turn-level success). Comparing dyads with high, medium, and low levels of accuracy in communication, growth curve modeling revealed a negative relationship between success and excessive variability in levels of Efficiency. Dyads performed better by maintaining moderately Fluid Efficiency (seen in high-success dyads) or minimizing Efficiency variability (seen in medium-success dyads), rather than scrambling for Efficiency only as needed (seen in low-success dyads). Balancing Efficiency variability in language production may create flexible but relatively stable interaction structures, laying the groundwork for successful communication.
