A method for the chip-producing machining of a gear wheel workpiece in a machine uses a cutting tool having at least two geometrically defined cutting edges, which produce material in chip form on the gear wheel workpiece during chip-producing machining. The chip-producing machining is defined by method parameters. The method includes computer-assisted analysis of the production of chips on the multiple cutting edges of the cutting tool and computer-assisted ascertainment of relative forces which will occur on the multiple cutting edges of the cutting tool during the production of chips. The method further includes optimizing the chip-producing machining to prevent the relative forces from exceeding a predetermined limiting value or reaching a limiting range. The optimization step includes providing adapted method parameters by modifying at least one of the method parameters. Chip-producing machining of the gear wheel workpiece is performed using the adapted method parameter(s).

The invention relates to a method for ascertaining topography deviations of a dressing tool. The method includes executing a predefined relative movement of a dressing tool in relation to a dressable grinding tool, wherein during the execution of the relative movement, at least one contour region of the dressing tool is transferred into a transfer region of the grinding tool. A plunging body made of material which can be ground in the machine is provided. The transfer region of the grinding tool is moved into the vicinity of the plunging body by a relative infeed movement. A rotational movement of the grinding tool around an axis of rotation is executed. Plunging the transfer region of the grinding tool into the material of the plunging body, to thus perform a transfer of the topography of the transfer region into an imaging region of the plunging body. A scanning movement of the topography is performed of the plunging body using a coordinate scanning sensor and a computational ascertainment by means of a computer of at least one item of coordinate information, which permits a statement about the actual geometry of the dressing tool.

Bevel gear cutting machine for chamfering and/or deburring edges on the teeth of a bevel gear. The gear-cutting machine comprises a workpiece spindle, which receives the bevel gear coaxially of a spindle axis. Furthermore, a deburring spindle is provided for the receiving of a deburring tool and several numerically controllable axes are given. A deburring blade head with several blade cutter-like blade inserts serves as deburring tool, whereby the blade inserts are insertable in recesses of the deburring blade head essentially radially oriented to a deburring spindle axis (E) and comprise edges for chamfering and/or deburring.

A bevel gear cutting machine, which is designed for, among other things, chamfering and/or deburring edges on the teeth of a bevel gear. The gear cutting machine has a workpiece spindle which receives the bevel gear coaxially. A carriage is provided, which receives a plate-shaped cutter head having multiple bar blades. The gear cutting machine has multiple numerically controllable axes, which are activatable via a programmable controller, one of the axes forming a workpiece spindle axis of the workpiece spindle. Another axis is used as the tool spindle axis of the plate-shaped cutter head. The numerically controllable axes are implemented and positioned so that by adjusting at least one of the axes, the workpiece spindle, together with the bevel gear, may be inclined in relation to the cutter head in such a way that the bar blades, while the workpiece spindle rotates around the workpiece spindle axis and the cutter head rotates around the tool spindle axis simultaneously, plunge one after another into tooth intermediate spaces of neighboring teeth and execute a chamfering or deburring motion in relation to the edge.

In a method and apparatus for machining spiral bevel gears a rotationally symmetric tool is driven about its axis of rotation as it is moved, along with a workpiece, into a respective initial starting position. The workpiece is rotated about one tooth index, and a complete tooth space is processed via a generating method to a preset generating depth. The tool and workpiece each reach first end roll positions and are then moved into respective second starting positions near the previously reached end roll position. The workpiece is once again rotated about a tooth index and another complete tooth space is generated using a roll direction reversed relative to the initial tooth generating process. The tool and workpiece reach a second end roll position near the first start position and these steps are repeated until all the tooth spaces of the workpiece have been processed.
