The effect of cutting conditions on power inputs when machining

Any technological process involving modification of material properties or product form necessitates consumption of a certain power amount. When developing new technologies one should take into account the benefits of their implementation vs. arising power inputs. It is revealed that procedures of edge cutting machining are the most energy-efficient amongst the present day forming procedures such as physical and technical methods including electrochemical, electroerosion, ultrasound, and laser processing, rapid prototyping technologies etc, such as physical and technical methods including electrochemical, electroerosion, ultrasound, and laser processing, rapid prototyping technologies etc. An expanded formula for calculation of power inputs is deduced, which takes into consideration the mode of cutting together with the tip radius, the form of the replaceable multifaceted insert and its wear. Having taken as an example cutting of graphite iron by the assembled cutting tools with replaceable multifaceted inserts the authors point at better power efficiency of high feeding cutting in comparison with high-speed cutting

Liberalist Fantasies: Zizek and the Impossibility of the Open Society

In this paper we engage with the liberalist project in organization and management studies. The first `face' of organizational liberalism is expressed through post-bureaucratic discourses which very much define the mainstream of management thought today, highlighting the need for organizational openness which can only come through a liberation of management from the closed structures of the bureaucracy. The second face of organizational liberalism defends the bureaucratic ethos of liberal-democratic institutions and points to the Popperian concept of the `open society' that requires rational, procedural laws to reconcile conflicting values in societies and organizations, thus ensuring the existence of a plurality of ways of life. We point to the limitations of both `faces' of organizational liberalism by discussing key aspects of Slavoj ?i?ek's work. ?i?ek displaces the liberal conception of institutionally sanctioned `openness' by claiming this actually constitutes a closure and puts a challenge to us. How can we create real openness? How is a real difference possible
