Embodiment Construction

[0081] figure 1 A machine tool assembly for machining a workpiece is shown in schematic form in FIG. 3 and is generally designated 10 .

[0082] The machine tool assembly 10 includes a clamping device 12 by means of which a workpiece 14 can be clamped. The workpiece 14 , also referred to here as a workpiece blank, comprises a cylindrical workpiece surface 16 , in the present case in the form of a drilled hole. The cylindrical workpiece surface 16 defines an annular edge 17 on the front side of the workpiece 14 .

[0083] The clamping mechanism 12 is designed to rotate the workpiece 14 about the longitudinal axis 18 , to be precise by means of a schematically shown rotary drive 20 which can rotate the workpiece 14 at a rotational speed n W turn.

[0084] The clamping mechanism 12 can also be equipped with a workpiece axial drive 22 , whereby it is possible to move parallel to the longitudinal axis 18 at a feed rate v W The workpiece 14 is driven. In some cases, the clampin...

Abstract

The invention relates to a method for fine machining a cylindrical workpiece surface (16) of a workpiece blank (14) by means of a fine machining tool (26). Said method comprising the following steps:generating a relative rotational movement (nW) between a tool (26) and a workpiece blank (14) about a machining axis (18) which is concentric to a cylindrical workpiece surface (16) of the workpiece blank (14); generating a relative feed rate (vW; vF) between the tool (26) and the workpiece blank (14) along the machining axis (18); detecting an actual value (TPIST; FPIST) of a process variable (TP; FP), which is a function of a relative force between the tool (26) and the workpiece blank (14) and which can assume a plurality of process variable values; and continuously controlling the processvariable (TP; FP) by changing the relative feed rate (vW, vF) in such a way that the more the relative feed rate (vW; vF) changes, the more the actual value (TPIST; FPIST) of the process variable deviates from a desired value (TPSOLL; FPSOLL) of the process variable (TP; FP).

Description

technical field [0001] The invention relates to a method for finishing a cylindrical workpiece surface of a workpiece blank by means of a finishing tool. The invention also relates to a device for machining the surface of a cylindrical workpiece, with: a clamping mechanism for the workpiece; a tool for machining the cylindrical workpiece surface of the workpiece; a rotary drive device so that between the workpiece and the tool producing relative rotation; and axially driving the device to produce a relative feed rate between the workpiece and tool. Background technique [0002] The present invention relates generally to the field of finishing of cylindrical workpiece surfaces. This type of finishing refers in particular to the machining process in which a cylindrical workpiece surface has been produced on the workpiece blank by means of a cutting tool, such as a turning tool, a drill, etc. The obtained cylindrical workpiece surface still needs to be improved in its quality...
