Embodiments of the present invention relate to a method and machine tool for machining a workpiece on the machine tool comprising at least 5 axes with a tool by using an NC program, the machine tool comprising a clamp for clamping a workpiece and a work spindle including a tool holder for holding a workpiece. The workpiece is clamped on the tool holder of the work spindle of the machine tool, the tool is clamped in the clamp of the machine tool, and the workpiece clamped in the tool holder of the work spindle is controlled in a program-controlled manner in relation to the tool clamped in the clamp for removing material from the workpiece.

Method and machine tool for machining a workpiece

A disclosed example method for generating control data for the formation of a tooth flank by milling a workpiece on a numerically controlled machine tool with at least 5 axes, at a universal machine tool, through successive passes with a milling cutter on the machine tool based on generated control data involves defining a geometry of a tooth flank, determining a contact pattern area on the predefined tooth flank geometry, determining parameters to vary the predefined tooth flank geometry, and generating control data on the basis of tooth flank geometry modified based on the defined contact pattern area and of the defined parameters.

Methods and apparatus for generating control data for the formation of a tooth flank by milling a workpiece on a machine tool

A process and an apparatus for generating control data, wherein a first tooth flank geometry is determined which corresponds to a geometry of a first tooth flank of the herringbone gearing, a second tooth flank geometry is determined which corresponds to a geometry of a second tooth flank of the herringbone gearing, a transition section geometry is determined which corresponds to a geometry of a transition section between the first tooth flank and the second tooth flank, an overall tooth flank geometry is determined which comprises the first tooth flank geometry, the transition section geometry and the second tooth flank geometry, and the control data is generated based on the overall tooth flank geometry and machining paths are indicated, each extending transversely to the profile direction of the tooth flanks and along the first tooth flank geometry, the transition section geometry and the second tooth flank geometry.

Process for producing a toothed wheel having a herringbone gearing and a process and an apparatus for generating control data to form a herringbone gearing on a workpiece

A disclosed example method for generating control data for forming a tooth of a spur gear toothing which has an intended widthwise crowning by milling a workpiece at a numerically controlled machine tool having at least 5 axes, at a universal machine tool, by successively moving a milling cutter of the machine tool along a plurality of machining paths based on the generated control data, involves providing a tooth flank geometry of at least one tooth flank of the tooth of the spur gear toothing. The method also involves determining parameters for specifying a change of the provided tooth flank geometry according to the intended widthwise crowing of the tooth. In addition, the method involves generating control data based on a tooth flank geometry which is changed based on the determined parameters, wherein the changed tooth flank geometry corresponds to a tooth flank geometry of the tooth having the intended widthwise crowing.

Methods and apparatus for generating control data for forming a tooth of a spur gear toothing by milling a workpiece at a machine tool

The present invention relates to a machine tool and a corresponding process for machining a workpiece by means of one or more tools controlled by means of control data, the machine tool comprising at least 5 simultaneously controllable axes. A control device being suited to control the tool supported in a support means by means of the control data along a tool path to remove material from the workpiece clamped in a clamping means. The machine tool being suited to machine a first workpiece to provide the first workpiece with a first gearing, the first workpiece being a counter piece to a second workpiece having a second gearing. The machine tool also comprising a test system suited to determine after and/or during the machining of the first workpiece on the machine tool whether a current geometry, in particular a current tooth flank geometry and/or current tooth gap geometry, of the first gearing of the first workpiece differs from a target gearing geometry, in particular from a target tooth flank geometry and/or target tooth gap geometry, of the first gearing of the first workpiece.
