Semi-completing single indexing methods for machining the tooth flanks of a face coupling workpiece. A tool is used which includes at least one cutting head having two cutting edges or two grinding surfaces. Exemplary methods include executing at least one first relative setting movement, to achieve a first relative setting, finish machining a first tooth flank of a tooth gap of the face coupling workpiece using a first cutting edge or using a first grinding surface of the tool and simultaneously pre-machining a second tooth flank of the second tooth gap using the second cutting edge or using the second grinding surface, executing at least one second relative setting movement, to achieve a second relative setting, and finish machining the second tooth flank of the same or a further tooth gap using a second cutting edge or using the second grinding surface of the tool.

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.

The present disclosure relates to a method for the gear manufacturing machining of a workpiece by a diagonal-generating method, in which the workpiece is subjected to gear tooth machining by the rolling off of a tool, wherein an axial feed of the tool takes place during the machining with a diagonal ratio given by the ratio between the axial feed of the tool and the axial feed of the workpiece. According to the present disclosure, the diagonal ratio is changed within the course of the machining of a workpiece.

A disclosed method utilizes virtual representations of gear profiles produced in view of accuracies and capabilities of specific machine and tool combinations to validate profile finishing parameters. The virtual representations are utilized to identify modifications needed to account for process capability and are implemented into the process to change the nominal profile utilized for producing the finished gear profiles. The resulting nominal gear profile accounts for process variations and thereby provides a more accurate and repeatable gear tooth profile.

The cavitation processing method, includes: immersing a nozzle that ejects a jet of a processing liquid of cavitation, a workpiece including a groove portion extending in a left-right direction and having edge portions at a front and a rear as viewed from the nozzle, and a guide member including a rectifying portion that flows the jet in a front-rear direction and a closing portion that closes a front end of the rectifying portion in the processing liquid; moving the closing portion to close to a front edge portion; ejecting the jet from the nozzle; and introducing the jet to the rectifying portion from the rear to cause the jet to collide with the closing portion for changing a flow direction of the jet to cause the jet to collide with a bottom portion of the groove portion.

A parallel axis gear configuration constructed in accordance to one example of the present disclosure can include a first gear having a first gear tooth that includes a lead crowning across a face width thereof. The lead crowning can include (i) a first lead crown defined from a centerline to a transition point and (ii) a second lead crown defined from the transition point to a first end point. The lead crowning can include a drop-off magnitude that is greater at the second lead crown than the first lead crown.

A machine tool and method for incorporating undercuts in left and right tooth flanks of teeth of a toothed gear blank by hob peeling, wherein the gear blank and a cutting wheel having cutting teeth with right and left cutting edges arranged at an axis intersection angle to the gear blank are continuously rotationally driven at a fixed speed ratio, the cutting teeth engage in the tooth flanks in a manner that removes shavings and the feed has at least one movement component in the direction of extension of the teeth of the gear blank.

The invention relates to a method for loading and unloading an internally toothed workpiece or a workpiece that is to be provided with internal toothing into/out of a clamping position, in which the workpiece, which is held by a retaining device, is brought into the clamping position by means of a conveying movement so that said workpiece, when clamped, has internal toothing cut by a gear cutting tool that occupies a cutting chamber and, after cutting, said workpiece, which is held by the retaining device, is returned from the clamping position in a return movement, wherein, prior to cutting, the retaining device is permitted to carry out an evasive movement that is different from the return movement/reverse conveying movement and that frees the cutting chamber, or the cutting chamber is already kept free of the retaining device as soon as the clamping position is reached.
