Method for the location determination of the involutes in gears

A method for location determination of involutes of a pre-gear cut workpiece within a gear-cutting machine using a gear-cut tool comprising the following method steps:

• generating a first relative movement between a workpiece and a tool, detecting a resulting first contact between a first tooth flank of the tool and a first tooth flank of the workpiece, and detecting a first set of coordinates for representing the first relative movement between the workpiece and the tool;
• generating a second relative movement between the workpiece and the tool, detecting a resulting second contact between a second tooth flank of the tool and a second tooth flank of the workpiece, and detecting a second set of coordinates for representing the second relative movement between the workpiece and the tool;
• and
• determining angles of rotation, feeds, an axial distance, and a crossed-axes angle of the tool and the workpiece based on the first and second sets of coordinates and calculating a location of the involutes based on the angles of rotation, the feeds, the axial distance, and the crossed-axes angle.
