| The invention concerns a method of machining a workpiece, wherein an end-facing tooth edge of a gear profile of the workpiece that was generated by a chip-removing machining process is reworked at a first location into a chamfered edge by way of a plastic forming operation. The material which in the plastic forming operation was displaced towards the end surface of the gear profile is pushed outward as a material protrusion in the end surface of the tooth, while the material displaced towards the flank of the tooth is pushed outward as a material protrusion on the flank side of the chamfer, and the resulting material protrusions in the end surface and on the flank side are removed. The workpiece, while still carrying the material protrusion on the end surface of the gear profile, is transferred to a second location where the protrusion on the flank side of the chamfer is removed. | ||||||

| A machine tool re-machines a workpiece after positioning drive motors, a hob and the workpiece by stopping the drive motors with the rotational positions of the drive motors, the hob and the workpiece corresponding to their respective zero positions. For this purpose, a drive control section recognizes, based on the rotational-speed ratio of the drive motor corresponding to the hob and the hob and/or the rotational-speed ratio of the drive motor corresponding to the workpiece to the workpiece, and detection signals from detection sensors detecting that the rotational positions of the drive motors are at their respective zero positions, detections signals when the rotational positions of the drive motors and the rotational positions of the hob and the workpiece correspond to their respective zero positions, and stops the drive motors with the rotational positions of the drive motors, the hob and the workpiece corresponding to their respective zero positions. | ||||||

| In a method for producing toothed sections on workpieces, a toothed section is firstly produced by means of a first tool in the region of a first end face of a workpiece to be toothed. The produced toothed section is reworked on the peripheral face by means of at least one second tool in the region of the first end face, while the toothed section is further produced. If the toothed section is also produced in the region of the second end face by means of the first tool, the reworking in the region of the first end face is already completed, so the toothed section can also be reworked in the region of the second end face. Short cycle times are thereby achieved with a low machine-related outlay. | ||||||

| A method for cutting teeth in workpieces, wherein, in a roughing operation, a substantially uncut blank receives rough teeth using a cutting tool having cutting teeth. Operation teeth are produced, the tooth width of which is defined by the spacing between the flanks of the teeth and is greater than the target dimension. In a subsequent deburring operation, a chamfer is incorporated into the end face edge of the tooth flanks, accompanied by the removal of an end face burr. Lastly, in a smoothing operation, the tooth width of the teeth is brought to the target dimension by machining the tooth flanks. | ||||||

| In a method for manufacturing a gearwheel, a gearwheel blank is clamped in a workholder of a multi-axis machine tool. A milling head is clamped in a tool holder which is rotated by a spindle drive to enable the milling head to mill out tooth spaces of the gearwheel blank to thereby create a gearwheel having teeth. After replacing the milling head in the tool holder with an inductor, the inductor is inserted successively between two adjacent teeth of the gearwheel and supplied with alternating current from a current supply device of the spindle drive to inductively heat at least one of the two adjacent teeth. The inductor in the tool holder is then replaced with a machining tool to remachine the teeth of the gearwheel. | ||||||

The second tool is moveable with the second stock along a line extending substantially perpendicular to and intersecting the work axis. The first stock is moveable to engage the first tool with the blank to form rough teeth. The second stock is moveable to engage the second tool with the blank. | ||||||

| An operating method improves the running behavior of gearwheels negatively noticed upon gearwheel testing and is performed by a burnishing device. The gearwheels that were rejected from the production process may be optimized rapidly and in a targeted way so that they may be returned back into the production process. The tooth flanks of a gearwheel to be machined are, in a first method step, mechanically freed of particles adhering to the surfaces of the tooth flanks or slight protrusions protruding therefrom using a first gearwheel machining tool having a machining wheel coated with an abrasive agent. Subsequently, in a second method step in a second gearwheel machining tool known as a burnishing machine, the gearwheel is chucked between gearwheel-shaped rolling tools, the so-called burnishing wheels, and rolled without material abrasion. | ||||||
