ABSTRACT:
A method and apparatus for the compensation of guiding errors in an incremental measuring instrument used in conjunction with machine tools or measuring machines is disclosed in which the measuring graduation is corrected in its mounting position in accordance with the error values of the machine. A preferred embodiment of this method is disclosed in which the error compensation is accomplished by the application of equal longitudinal compression or extension forces to the ends of the measuring graduation.
