Abstract
A method for the machine-milling of intake and/or exhaust ducts formed in a cylinder head includes working off the inner wall surfaces of the intake and/or exhaust ducts at least in part, preferably completely, with a multi-axis, preferably five-axis, CNC-controlled cherry head in a stabbing movement. Grooves are thus formed in the inner wall surfaces that extend primarily in the flow direction of the ducts.
