摘要
A method of machining mechanical workpieces, in particular of machining the brakingsurfaces (2, 3) of a brake disc (1) for vehicles is described and comprises the steps of loading theworkpiece onto a work station (8) and clamping the workpiece in a median reference plane (A)between the opposed braking surfaces (2, 3), as well as defining the excess material thickness to beremoved from each of the said surfaces, with respect to the positioning coordinates of the said planein relation to a system of working axes of the station, to achieve a balanced, centered division ofexcess metal removed from the said surfaces (2, 3). The method also comprises the steps ofpreliminary loading and clamping the workpiece on a handling device (7) operatively controlled bythe work station (8) for the machining of the workpiece, the workpiece being gripped on the handlingdevice (7) in the region of the said median place (A), of bringing the said device (7), towards aworkpiece-holder chuck (10) of the work station (8) with subsequent measurement of the positioningco-ordinates of the said median plane (A) in relation to the system of working axes, and of clampingthe workpiece on the chuck (10) of the workstation and releasing the handling device (7) to allowboth of the opposed workpiece surfaces (2, 3) to be machined in the said work station (8) by removalof the preselected excess material thicknesses calculated in relation to the positioning co-ordinates ofthe said plane (A).[IN227799A1]
