Adaptation of turning technological systems for obtaining complex profile surfaces in part cross-section

In this paper, an algorithm is presented for enabling software to predict the trajectory of machining allowance removal, which will provide the possibility to create various surfaces by the turning process. Economic realities in the manufacturing sector of the economy constantly push manufacturers to reduce production costs simultaneously increasing quality indicators. The analysis and application of an innovative processing method allows a fresh look at the application and modernisation of modern equipment available at a factory and expansion of its technological capabilities by reducing the number of operations performed by various types of metal-cutting equipment, as well as by automation of the process of obtaining the required surface configuration with the possibility of quick readjustment, which results in increased productivity and an expanded range of products. A pattern of surface obtaining under turning with a rotating tool is developed. The formulae for complex asymmetric product profile production are derived. The algorithm is compiled and the software code is developed in the Scilab environment for modelling in order to obtain the cutting tool movements along a complex path and its analysis. The tool movements per one revolution of the workpiece are calculated and a model of the tool trajectory is constructed. A table of profile modelling data obtained at various rotation speeds of the tool and workpiece has been compiled. The presented algorithm and algorithm-based software allow the trajectory of machining allowance removal to be predicted, which can facilitate the production of various surfaces by turning, e.g. ellipses, polyhedrons, cams in the form of flat spirals, etc.
