Reducing energy consumption in manufacturing is essential for using energy effectively and minimising carbon footprint. In this study, the equation for selecting optimum cutting conditions to minimise energy footprint was extended by considering the fact that as tool wear increases, power and specific energy also increase. This new model enables selecting optimum conditions for energy-smart machining by considering energy footprint, cutting tool utilisation and the volume of material to be removed. This timely research improves the integrity of energy models in machining and their suitability and impact in practical machining conditions.

This paper shows a process of selection of optimum conditions for laser remelting of nodular cast iron. The optimisation takes into account a specified depth of the hardened layer, for which an appropriate energy input is specified while taking into account the mode of guiding the laser beam. Strain criteria are given for the optimisation of the remelting process, i.e., minimum energy input at a given depth of the hardened layer, minimum distortion of the machine part and a desired variation of residual stresses across the hardened layer. Practical tests of optimisation showed the logic of adhering to the aforementioned criteria, because we can significantly influence the quality of the product at lower costs of manufacturing.

The research in the last decade regarding their cutting machinability have highlighted the insufficiency of the data for establishing of the optimum cutting processing conditions and the optimum cutting regime. The purpose of this paper is the optimization of the tool life and the cutting speed at the drilling of the stainless steels in terms of the maximum productivity. A nonlinear programming mathematical model to maximize the productivity at the drilling of a stainless steel is developed in this paper. The optimum cutting tool life and the associated cutting tool speed are obtained by solving the proposed mathematical model. The use of this productivity model allows greater accuracy in the prediction of the productivity for the drilling of a certain stainless steel and getting the optimum tool life and the optimum cutting speed for the maximum productivity. The obtained results can be used in production activity, in order to increase the productivity of the stainless steels machining. Finally the paper suggests new research directions for the specialists interested in this field.

A versatile radioimmunoassay for serum oestriol in pregnancy has been developed which requires 10 μ| of serum (for total) or 50 μ| (for unconjugated). Selection of the optimum conditions for the hydrolysis of serum oestriol conjugates, the isolation of free oestriol, the displacement of tritiated oestriol by cold oestriol and the separation of the free and bound fractions is described. Total oestriol levels doubled between weeks 34 and 38 of normal pregnancy, very little change occurring in the mean level after the 38th week of gestation. In a random series of pregnancy sera there was a significant correlation between total and unconjugated oestriol.

Poor Outcomes

<p>This talk will report on the multiple research streams resulting from the Living Well Within Limits project. The Living Well Within Limits project investigates the energy requirements of well-being, from quantitative, participatory and provisioning systems perspectives. In this presentation, I will communicate individual and cross-cutting findings from the project, and their implications for the engineering research community. In particular, I will share our most recent results on global energy footprint inequality, implications of redistribution, as well as modelling the minimum energy demand that would provide decent living standards for everyone on earth by 2050. I will show that achieving low-carbon well-being, both from the beneficiary (“consumer”) and supply-chain (producer) sides, involves strong distributional and political elements. Simply researching this area from a technical, social or economic lens is insufficient to draw out the reasons for poor outcomes and most promising avenues for positive change. I thus argue for the active engagement of the research community.</p>

This paper presents a program for the automatic design of special tools developed under a CAD/CAM (computer aided design/manufacture) system. In particular, the special tools made with standard components have been considered. Since the design of these types of tools was essentially related to the selection of their components, this paper deals with this aspect, insisting upon the selection of those components directly related to the removal of material: the toolholders or cartridges and the inserts. To select these components it is necessary to take into account not only geometrical or technological rules but also economical ones, owing to the high amount of possible components they can select. Consideration of economical aspects required the formulation of the cost equation associated with the use of these types of tools, characterized because their cutting edges coincide with different cutting velocities. Likewise, consideration of economical aspects allows the selection of the optimum cutting conditions and the cutting components to take place at the same time. Some of the geometrical and technological parameters related to the selection of cutting components are automatically identified by the system through an automatic identification of the workpiece profile.
