Patent ID: 7137865

Claim:
A method for the division of a single crystal material with a cutting tool of a cutting device, the method comprising: orienting the single crystal material in the cutting device such that a specified crystallographic orientation (K) lies in the cutting plane (T); positioning the single crystal in the cutting device so that an angle (ρ) between the specified crystallographic orientation (K) and a direction of advancement (V) of the cutting through the single crystal material is formed such that forces acting on the cutting tool during cutting in a direction at right angles to the cutting plane (T) compensate one another or add up to a predetermined force; cutting the single crystal material in the cutting device by moving the cutting tool relative to the single crystal material in the direction of advancement (V); measuring a deflection (X) of the cutting tool during the cutting; and turning the single crystal as a function of the measured value with the specified crystallographic orientation (K) in the cutting plane (T).
