The invention relates to a method for the chip-removing production or machining of a workpiece by means of a tool, in which method a liquid, which mixes and accumulates with the chips produced during the machining process, is used for lubricating and/or cooling the machining process, and the chips are discharged from the accumulation counter to the downhill force along a discharge path by means of a magnetic force, wherein a return flow of the liquid carried by the discharged chips occurs due to the downhill force, and the return flow is deflected out of the discharge path and/or the discharge path has at least one point at which the supporting surface is temporarily withdrawn from the discharged chips.

The invention relates to a method for generating a workpiece () having a second tooth system () incorporated into a first tooth system () having a specified tooth system geometry, wherein a first generative processing engagement, intersecting the second tooth system in the kinematics of the generating skiving, is made on the workpiece, which is in particular oversized in relation to the specified tooth system geometry, in particular on a transition from the first to the second tooth system, and then a second processing engagement, matching the specified tooth system geometry, in the kinematics of the generating skiving is carried out on the transition and a remaining oversize is in particular removed while doing so. The invention further relates to tools and to tooth-cutting machines suitable therefor.

The invention relates to a method for machining a workpiece, wherein, in particular in the skiving process, a toothing is produced on the workpiece in a first machining operation, in which a toothed cutting wheel, which rotates about the axis of rotation thereof and, on a first end face, comprises cutting edges on the toothing thereof, is coupled in a rolling manner to the workpiece which rotates about the axis of rotation thereof, and a cutting movement of the cutting edges, which has directional components in parallel with the workpiece axis, ends at an axial side of the workpiece toothing, the cutting edges of the cutting wheel forming a first operating region which can be positioned with respect to the workpiece by means of movement axes, and in which, in a second machining operation using a second operating region, the workpiece is machined on the side of the workpiece toothing at which the movement ends, wherein the second operating region can be positioned with respect to the workpiece by means of the same movement axes as the first operating region, and in particular is coupled for movement to the first operating region.

The invention concerns a method for the machining of the tooth edges between an axially facing surface and the tooth flanks of a gear with a machining tool that has a toothed contour. For the material-removing cutting operation, the machining tool, rotating about the axis of its toothed contour, is brought into rolling engagement with the toothed workpiece under a crossing angle different from zero between the rotary axes of the machining tool and the toothed workpiece.

A coolant delivery system which serves to deliver a cooling agent whose purpose is to carry away the heat that is generated in the process of machining a toothed profile by means of a skiving wheel rotating about its rotary axis. The coolant delivery system provides for a delivery path section which, seen in a projection onto a plane extending orthogonal to the rotary axis, is arranged closer to the axis than the toothed profile of the skiving wheel and has a dimensional component in the axial direction.

A profile gauge that embodies a measurement geometry for a tool that has a toothed profile designed in particular for the skiving of toothed work pieces, wherein the profile gauge serves to determine at least one measurement quantity which can be used for a machining process, specifically a skiving process, that is to be performed with the tool and wherein, in a phase of said process, the toothed profile of the work piece that is to be generated is formed by a meshing engagement with the teeth of the tool, wherein the profile gauge is distinguished by having a toothed profile section with which, for determining the measurement quantity, the teeth of the tool are brought into a meshing engagement that corresponds to the tooth engagement between the tool and the work piece during the profile-forming phase. The invention further concerns a measuring device and a measurement method.

The invention concerns a method of grinding a toothed workpiece in which a central axis of the toothed contour profile is defined, wherein the method encompasses at least two work operations. In a first work operation a grinding zone of a grinding tool whose selection is determined by the grinding process to be performed, which rotates about an axis of rotation and is set up for an infeed in the direction of the shortest distance between said central axis and the rotation axis, is brought into grinding engagement with a tooth flank of the workpiece. In a later, second work operation, the tooth flank is brought into grinding engagement with a grinding zone of a grinding tool whose selection is determined by the grinding process to be performed and which is advanced in the infeed direction of the first operation. The grinding zone that is active in the first work operation is dressed in a first dressing operation with a dressing tool, and the grinding zone that is active in the second work operation is dressed in a second dressing operation with a dressing tool, wherein in the first dressing operation a first dressing tool zone is brought into dressing engagement with the grinding zone that is to be dressed, and in the second dressing operation a second dressing tool zone which is spatially separate from the first dressing tool zone is brought into dressing engagement with the grinding zone that is to be dressed.
