Abstract
One or more workpieces having a desired gear geometry may be produced by means of a suitably dressed tool which is respectively dressed by a dresser after the carrying out of one or more machining steps before further machining steps are carried out at the same workpiece or at further workpieces. A relative position between the dresser and the tool may be changed by a corresponding additional adjustment of the axes of movement of the dressing machine in a later dressing process with respect to an earlier dressing process in addition to the smaller center distance resulting from the smaller tool diameter.
Claims16
A method of manufacturing one or more workpieces having a desired gear geometry by means of a suitably dressed tool, wherein, after the carrying out of one or more machining steps, the tool is respectively dressed by a dresser of a dressing machine before further machining steps are carried out at the same workpiece or at further workpieces, wherein on a later dressing procedure, the relative position between the dresser and the tool is changed with respect to a prior dressing procedure in addition to the smaller center distance resulting by the smaller tool diameter by a corresponding additional adjustment of the axes of movement of the dressing machine.
A method of manufacturing one or more workpieces having a desired gear geometry by means of a suitably dressed tool, wherein, after the carrying out of one or more machining steps, the tool is respectively dressed before further machining steps are carried out at the same workpiece or at further workpieces, wherein in a later dressing procedure, the profile angle of the tool is changed with respect to an earlier dressing procedure so that the workpiece or workpieces is or are gear manufacturing machined with a different profile angle of the gearing of the tool after the later dressing procedure than after an earlier dressing procedure performed before the later dressing procedure, wherein the profile angle is respectively selected such that a deviation of the gear geometry resulting on the workpiece is reduced or minimized with respect to a desired gear geometry;
- and/or wherein a stretching and/or compression of a modification produced on the tool by a modified dresser is reduced or minimized by the change of the profile angle.
A method of manufacturing a workpiece having a desired gear geometry by means of a tool suitably dressed by a modified dresser, comprising the steps:
- specifying a desired gear geometry of the workpiece;
- and
- determining a suitable profile angle of the tool and a suitable relative position between the dresser and the tool during the dressing of the tool for providing the desired gear geometry of the workpiece at least within a permitted tolerance in the machining by the tool.
A method for the modified dressing of a tool which can be used for the gear manufacturing machining of a workpiece on a dressing machine, wherein a modified dresser is used for dressing the tool, wherein the axes of movement of the dressing machine are set during the dressing of the tool and/or the macrogeometry of the tool and/or of the dresser, and wherein the number of starts and/or the diameter and/or the profile angle and/or the conical angle of the tool and/or the diameter of the dresser is/are selected such that the modification of the dresser is applied to the tool compressed or stretched by a specified amount and/or is applied to the workpiece compressed or stretched.
