Abstract: A method for establishing different parameters of a surface of a work piece during machining of the surface using a spindle supporting a tool and displacement sensors for measuring displacement to which the spindle is subjected during machining. The method involves machining work pieces with different back off times to create sets of sensor signals representing spindle deflections. The machined work pieces are measured and then the stored sensor signals are compared with the measurement results of the same work pieces. Transfer constants are calculated representing the influence of the total deflection of the machine stiffness on the sensor signals. Displacement sensor signals obtained upon machining subsequent work pieces are processed with the transfer constants to give a series of sensor signals representing the true total deflection of the loaded and running machine stiffness chain to permit calculation of different parameters of the subsequently machined work pieces.

Abstract: Patent Method for manufacturing improved contact surfaces, particularly contact surfaces in rolling bearing components such as rings or rolling bodies, is disclosed. The method subjects a surface of the rolling bearing component to a hard turning machining operation for forming by means of a hard turning tool a rolling or sliding contact surface. The hard turned surface is subjected to a finishing operation to remove the basic turning groove structure in a light machining way such that micro-pockets created in the hard turning operation remain. The hard turning tool during the hard turning machining operation is subjected to a vibration, substantially in the longitudinal direction of the tool, thereby creating in a controlled manner in the hard-turned surface a number of indentations, which are substantially arc-shaped in cross-sectional direction, prior to the finishing operation. Indentations improve lift-off and lubricating properties during later operation of the rolling bearing.
