METHOD AND MEASURING STATION FOR DETERMINING THE STRAIGHTNESS OF BAR CONDUCTORS
The invention relates to methods and devices for simply and precisely determining the straightness of bar conductors. Bar conductors to be examined are placed onto two supports which are spaced apart from one another, and a gravity-induced deflection of the respective bar conductor between the supports is determined. A nominal deflection of a perfectly straight bar conductor is determined implicitly from a mean value of deflections which are produced when bar conductors are placed onto the supports in two orientations which are turned by 180° about their longitudinal axis. The straightness of the bar conductor is extrapolated from a comparison of the deflection in one of the orientations of the bar conductor with the nominal deflection. The nominal deflection can be determined for each bar conductor individually from the two deflections in the case of a support of this bar conductor turned by 180°; in this case, the difference in the deviations specifies a measure of the deviation from the nominal deflection, without this needing to be explicitly calculated. As an alternative, the nominal deflection can be determined for identical bar conductors explicitly by way of two-sided measurement of one or more bar conductors; for further identical bar conductors, only a single deflection then needs to be determined which is compared with the nominal deflection. In this way, the straightness in the two planes which are perpendicular with respect to the flat sides can be determined for bar conductors with a rectangular cross section.

Method of producing rotationally symmetrical surfaces on a workpiece
The invention relates to a method, in particular a turning method, for producing a rotationally symmetrical surface on a rotating workpiece (1), wherein a cutting edge (3) is inserted into the workpiece (1) many times.

At least one transport module (8) can be displaced along the row below the positions of the stacks and said transport module supports a lifting device (21). One palette or a stack of palettes are moved from below by means of the lifting device. Said inventive preparation module can manage, in an economic manner, a large number of stack positions and palettes, and said stacks can also be stacked to a high level.
The invention relates to a process, in particular a turning process, for the manufacture of a rotationally symmetrical area on a rotating workpiece (1), where a tool cutting edge (3) is inserted many times into the workpiece (1). Each insertion produces a new profile section (11), also termed a groove. The insertion positions are so tightly spaced that the resultant profile (7) produced on the workpiece (1) is composed exclusively of residual profiles or residual grooves which adjoin one another and which derive from the new profile sections or grooves (11). Any interim profile sections produced between the insertion positions during the repositioning of the tool cutting edge (3) are in turn removed during subsequent insertion. The resultant rotationally symmetrical area is free from swirl effects. The process can be carried out with conventional lathes.
