Main Article Content
Abstract
Combined rapid machining of incomplete spherical surfaces of parts is considered, formulas for calculating the cutting temperature taking into account the angle of contact between the tool and the workpiece are derived, the results of experimental studies of the temperature of the part and chips depending on the processing time, as well as modeling of cooling air flows in the tool and the cutting zone are presented.
