Evaluation of machinability by high speed milling of two steels by means of cutting forces
Journal Title: Proceedings in Manufacturing Systems - Year 2015, Vol 10, Issue 2
Abstract
One of the criteria used in order to evaluate the materials machinability by milling is the size of mechanical solicitation of the milling technological system. Usually, this mechanical solicitation is evaluated by means of cutting forces and moment. By knowing the sizes of milling forces and moments, one can adequately establish the values of milling process parameters and design or test the behavior of distinct components of the technological system under the action of the milling forces and moment. A systemic analysis of the end milling process highlighted the main groups of factors able to exert influence on the sizes of milling force components and moments. Taking into consideration the available conditions, an experimental plan was elaborated and materialized, in order to establish mathematical empirical models which could highlight the influence exerted by the workpiece material hardness and the parameters of milling process on the sizes of milling force components. Power type empirical models were determined by mathematical processing of the experimental results. The empirical models allowed the highlighting of the influence order of the considered factors. A more suggestive illustration of the influence exerted by the input factors on the sizes of the end milling force components was obtained by means of some graphical representations.
