Method for measuring workpieces (26; 36), wherein the workpieces (26; 36) are of the same type and wherein, • for a multiplicity of the workpieces (26; 36) of the same type, in accordance with a measurement specification, a surface point of the workpiece (26; 36) is measured as a measurement point (27, 28; 38) designated by the measurement specification in each case at the same specified position with respect to a coordinate system of the workpiece and a measurement value is obtained as a result for each measured workpiece, • from a previously performed measurement of other workpieces (26; 36) of the same type, in which in each case the same designated measurement point (27, 28; 38) and a multiplicity of further surface points were measured as further measurement points for the other workpieces (26; 36), a piece of information relating to an existing correlation between the measurement values of the designated measurement point (27, 28; 38) and the measurement values of the further measurement points is available, characterized in that, • in addition to the designated measurement point (27, 28; 38), also at least one surface point is measured as an additional measurement point (29, 30) in accordance with the measurement specification during the measurement of the multiplicity of the workpieces (26; 36) of the same type for each of the multiplicity of the workpieces (26; 36), so that one measurement value for the designated measurement point and one measurement value for each additional measurement point is obtained as a result for each measured workpiece, • the additional measurement point lies in a surface region in which, in accordance with the piece of information from the previously performed measurement, a correlation between the measurement values of the designated measurement point (27, 28; 38) and the measurement values of the additional measurement point (29, 30) is expected, and • a check is carried out by evaluating the measurement values of the designated measurement point and the measurement values of the additional measurement point (29, 30) or the additional measurement points as to whether there is a correlation between the measurement values of the designated measurement point (27, 28; 38) and the measurement values of the additional measurement point (29, 30) or of the additional measurement points and/or how high the correlation is, and a result of the check is output. • for a multiplicity of the workpieces (26; 36) of the same type, in accordance with a measurement specification, a surface point of the workpiece (26; 36) is measured as a measurement point (27, 28; 38) designated by the measurement specification in each case at the same specified position with respect to a coordinate system of the workpiece and a measurement value is obtained as a result for each measured workpiece, • from a previously performed measurement of other workpieces (26; 36) of the same type, in which in each case the same designated measurement point (27, 28; 38) and a multiplicity of further surface points were measured as further measurement points for the other workpieces (26; 36), a piece of information relating to an existing correlation between the measurement values of the designated measurement point (27, 28; 38) and the measurement values of the further measurement points is available, • in addition to the designated measurement point (27, 28; 38), also at least one surface point is measured as an additional measurement point (29, 30) in accordance with the measurement specification during the measurement of the multiplicity of the workpieces (26; 36) of the same type for each of the multiplicity of the workpieces (26; 36), so that one measurement value for the designated measurement point and one measurement value for each additional measurement point is obtained as a result for each measured workpiece, • the additional measurement point lies in a surface region in which, in accordance with the piece of information from the previously performed measurement, a correlation between the measurement values of the designated measurement point (27, 28; 38) and the measurement values of the additional measurement point (29, 30) is expected, and • a check is carried out by evaluating the measurement values of the designated measurement point and the measurement values of the additional measurement point (29, 30) or the additional measurement points as to whether there is a correlation between the measurement values of the designated measurement point (27, 28; 38) and the measurement values of the additional measurement point (29, 30) or of the additional measurement points and/or how high the correlation is, and a result of the check is output.
