Abstract
This paper presents the results of experimental studies on the influence of the turning process parameters on the values of specific cutting force kc. with the use of different grades of carbide inserts. Three variables were analyzed, i.e. cutting speeds vc, depth of cut ap and feed f, for dry turning of the difficult-to-cut titanium alloy Ti6Al4V ELI. In the cutting tests, two types of inserts were used and made of two different grades of cemented carbides, ie, H13A and 1115. To determine the specific cutting force (SCF), a measuring system was used to trace and record the circumferential cutting force Fc. According to the adopted research plan, a total of 36 test systems were determined, on the basis of which the values of the kc coefficient were determined. The significance of the influence of the machining parameters on the SCF values was analyzed. The tests showed that the specific cutting force kc depends primarily on the cross-sectional area of the cutting layer, that is, directly on the feed value and depth of cut. Furthermore, it has been shown that turning with coated inserts results in a lower specific cutting force, which can directly translate into an increase in tool life. The mean value of the kc coefficient for the use of a cutting insert without coating differed from a cutting insert with a coating of 282.7 MPa (1952.2 MPa compared to 2234.9 MPa). Furthermore, a higher tendency for surface hardening and built-up edge was observed in the cutting tests for uncoated tool turning. The obtained results allowed to present the recommended ranges of machining parameters for dry turning of the processed material. The presented results can provide practical guidelines for the selection of cutting parameters for the machine industry and contribute to the reduction of costs and the negative impact on the environment of machining with the use of cutting fluids. The obtained research results were analyzed and concluded according to the Taguchi method. Based on the desirability function and the response surface methodology, cutting speed vc = 80 m/min, depth of cut ap = 1.0 mm and feed f = 0.2 mm/rev were selected as optimal machining factors.
