Method for designing and machining a gear wheel, and corresponding machine tool and software

Method for the grinding of a gear wheel workpiece using a dressable worm grinding wheel, wherein the worm grinding wheel is rotationally driven about a tool axis of rotation and the gear wheel workpiece is rotationally driven about a workpiece axis of rotation, and relative movements are executed between the worm grinding wheel and gear wheel workpiece, and wherein after the execution of a dressing procedure of the worm grinding wheel, which is carried out by means of a rotationally-drivable dressing unit, the following steps are carried out:

Method and grinding machine for grinding a gear wheel workpiece

A method for continuous generating grinding of at least two gear workpieces with a topologically modified grinding worm comprising a topologically modified worm region to grind tooth flanks which are topologically modified on the gear workpieces, wherein the method comprises at least the following steps:

Grinding machine with control system and method for topological grinding of gear workpieces

Method for the face-side chamfering of gear teeth of a workpiece () in a CNC-controlled multiaxis machine including inserting a tool () in the multiaxis machine, wherein the tool () has at least one cutting tooth () having a first rake face and a second rake face, driving the tool () in a first rotational direction, executing first CNC-controlled relative movements while the tool () rotates in the first rotational direction to chamfer a first face-side edge () of a first tooth of the gear teeth using the first rake face of the tool (), and executing second CNC-controlled relative movements while the tool () rotates in the first rotational direction, to chamfer a second face-side edge () of the first tooth or another tooth of the gear teeth using the second rake face of the tool (), and apparatus therefor.

Method and device for the face-side chamfering of gear teeth of a workpiece

Method for power skiving a workpiece () having a workpiece axis of rotation (R) and having a rotationally-symmetrical, periodic structure using a power skiving tool ().

Power skiving method having multiple cut strategy

A method and an apparatus for skiving a work piece that has a rotationally-symmetric, periodic structure, by applying a skiving tool. The skiving tool has a tapering collision structure. During skiving, a coupled relative movement of the skiving tool in relation to the work piece is performed. The skiving tool is rotated about a first rotation axis and the work piece is rotated about a second rotation axis. A negative tilt angle is set during skiving, and the first rotation axis runs skew with respect to the second rotation axis.

Method for skiving and according apparatus comprising a skiving tool

A power skiving tool for producing multiple tooth gaps by means of a power skiving method on a ring-shaped or disk-shaped workpiece, which has a workpiece axis of rotation is provided. The power skiving tool includes a tool axis of rotation, a skiving conical body, which is in the form of a hyperboloid or truncated cone, and which is arranged rotationally-symmetrically to the tool axis of rotation, and multiple cutting teeth, which protrude essentially radially out of a lateral surface of the skiving conical body. Each of the cutting teeth has a rake face and at least one cutting edge, and all rake faces have a cutting surface normal, which encloses an acute angle, which is less than 40&#xb0;, with the tool axis of rotation, and wherein the power skiving tool is designed for axially-offset power skiving of the workpiece.

Power skiving tool for power skiving gear teeth on a crown wheel workpiece

Apparatus and method for skiving first and second work pieces using the same skiving tool to machine both work pieces. Flank cutting edges of the skiving tool subjected to a stronger load during machining of the first work piece are subjected to a lesser load during machining of the second work piece and vice versa. Accordingly, a substantially uniform load is subjected to both flank cutting edges overall, resulting in improved uniformity of wear to both flank cutting edges.

Semi-completing skiving method and device having corresponding skiving tool for executing a semi-completing skiving method

Method and an apparatus for setting up and plunging a skiving tool with respect to a work piece, on which a rotational-symmetric, periodic structure is to be manufactured with application of the skiving tool, wherein a radial feed motion in the direction of the work piece is performed, so to bring the skiving tool in contact with the work piece for the first time, and the skiving tool is plunged from the moment of the first contact down to a predetermined depth in a radial plunging movement, before the proper skiving of the rotation-symmetric, periodic structure is carried out.

Robust method for skiving and corresponding apparatus comprising a skiving tool

A skiving tool for manufacturing a rotationally symmetrical periodical structure on a work piece by means of a power skiving method. The skiving tool comprises a base body comprising a central rotation axis and a plurality of receiving openings and a plurality of cutter bars, fewer than or equal to the number of receiving openings. Each of the receiving openings has an elongate shape having a longitudinal axis, and the receiving openings can be arranged uniformly around the central rotation axis. The longitudinal axes of the receiving openings are generators of a rotation hyperboloid, which is arranged rotationally symmetrical to the central rotation axis.

Skiving tool comprising cutter bars

Method for the optimization of the surface geometry or of a variable, dependent on this, or variables, dependent on this, of bevel or hypoid gears for their production on a free-form machine which can be mapped to a free-form basic machine with at most six axes uniquely in a reversible way, even to symmetries, which has a gearwheel to be machined and a tool which are in each case rotatable about an axis, and the tool and the gearwheel to be machined are moveable, preferably displaceable or rotatable, with respect to one another along or about a plurality of axes, the optimization of the surface geometry or of the variable or variables, dependent on this, of the bevel or hypoid gearwheel taking place in that one or more control parameters, which has or have influence on the surface geometry or the variable or variables, dependent on this, of the bevel or hypoid gearwheel, is or are varied by means of a simulation of the gearwheel production process and/or a roll and/or a load-contact analysis on the free-form basic machine, until the surface geometry or the variable or variables, dependent on this, of the bevel or hypoid gearwheel thereby corresponds at least to a predetermined target value.
