Prediction of Parameters for the Burr Dimensions in Short-Hole Drilling

A simple analytical model for burr type prediction in drilling of ductile materials

“…Burr is usually described by its height and its thickness, tagged as h0 and bg for example in [10] and [11]. Other geometrical parameters may be necessary to characterize more precisely the burr geometry, see for example rf and bf in [11].…”

Comparison of machine learning algorithms for optimization and improvement of process quality in conventional metallic materials

“…The numerical results obtained through the calculation of finite elements which include a model of the damage, fractures and the effect of wear of the tool are used to train the simulation environment developed through the neural network. Heisel et al [13] propose a method based on empirical tests of the cut and the correlation between the burr generated and the operating conditions of the machine such as the speed of the cut or the geometry of the tool. Lauderbaugh [17] presents a method to combine different experimental tools, simulation and statistics with the aim of predicting the height of the burr, the strength and flow of the heat and the temperature.…”

Burr formation in intersecting holes

“…If the course of the burr value as a function of feed is compared with the course of the yield stress k f of steel materials, a dependence of the yield stress and thus also of the temperature T GB in the burr forming area can be established [8].…”

“…In [8] an analytical model is presented which, based on empirical cutting examinations, can calculate the expectable dimensions of arising burrs depending on the given machining parameters. The model was established and verified for the materials 16 MnCr 5 and C45E in the case of dry machining.…”

“…If the parameters are substituted into the equation, and if, based on the calculation method presented in [8], the burr value is determined for the square indexable insert with chamfer in the case of perpendicular exit surfaces, then the courses shown in Fig. 5 result for the exit surface angles of a S = 15°and 30°.…”
