Much of the difficulty in assessing theories of consciousness stems from their advocates not supplying adequate or convincing characterisations of the phenomenon (or data) they hope to explain. Yet, to make any reasonable assessment this is precisely what is required, for it is not as if our ‘pre-theoretical’ intuitions are philosophically innocent. In what follows, I will attempt to reveal, us...
Assumption of cutting disturbances in hard turning process (caused by variations in depth of cutting, high passive force Fp or small tool nose radius) could be confirmed with several indicators. These indicators can be monitored during turning process(forces, vibrations, sound, etc.) or after process has been finished (roughness, temperature, wear, etc). Variation of depth of cutting as well as...
An experimental study has been performed to investigate the capabilities of dry, conventional and high pressure jet assisted turning of two different hard-to-machine materials, namely hard-chromed and surface hardened Ck45 and Inconel 718. The capabilities of different hard turning procedures are compared by means of chip breakability, technological windows, cooling lubrication efficiency, and ...
Surface roughness is an important parameter to evaluate the quality of a machining process in mechanical manufacturing. The construction surface model basis for predicting corresponding each certain case. This paper presents 080A67 steel turning. An experimental was carried out with total 15 experiments, designed according Box-Behnken matrix. cutting speed, feed rate, and depth were changed exp...
In this paper, multi-objective optimization of hard turning has been reported. A neural network model was developed in order to model the surface roughness and tool wear characteristics of hard turning when CBN tools are used. Objective is to obtain optimum process parameters, which satisfies given limit, tool wear and surface roughness values and maximizes the productivity at the same time. A ...
