Methods for machining may include: (a) providing a bevel gear on a workpiece spindle of a machine, the gear having a tooth having a head, (b) rotationally driving the gear about an axis of the spindle, (c) providing a first machining tool on a tool spindle of the machine, (d) machining the gear by means of the first machining tool, (e) providing a grinding tool as a second machining tool on the tool spindle or on a further spindle, (f) driving the grinding tool to rotate about a tool axis of the tool spindle, wherein the grinding tool comprises a concave machining region that has a ring shape and is arranged concentrically in relation to the tool axis, and (g) advancing the grinding tool in relation to the gear to bring the machining region into chip-removing operational connection with an edge in a region of the head to produce a chamfer on the edge by grinding.

Method for finish machining of a bevel gear in a region of a tooth head, machine for machining bevel gears, and grinding tool for use in association therewith

A method for operating a plurality of measuring machines (), wherein measuring machines () of the same type are concerned which are designed for the measurement of same parts (), having the following steps: &#x2014;measuring a first quantity of same parts () in a first measuring machine (); &#x2014;measuring a second quantity of same parts in a second measuring machine (); &#x2014;performing a comparison process, wherein within the scope of said comparison process at least one value (W) of the first quantity is correlated with at least one respective value (W) of the second quantity in order to determine therefrom; and deviations between measurements of the first measuring machine () and measurements of the second measuring machine ().
