A method and apparatus for producing a measuring graduation for position measuring systems as well as measuring standard

摘要

The invention relates to a method and a device for the production of the measurement members (1) as well as a measuring graduation. Around the pole boundaries (6) between the in the measuring standard (1) a agne tisi though poles (n, s) to configure and sharply to both sides of the pole boundaries (6) to achieve symmetrical magnetization, is provided according to the invention that at least one track of the measuring standard at least in sections with a coarsely magnetization field (13) with a first relative to the surface (8) of the measuring standard aligned field directions occur at each of the (f_G) is magnetized and alternately poles (n, s) of different polarity are generated (2, 3). In the region between the the coarse magnetization field (13) of the magnetic poles of the track is generated at least in sections with a finely magnetization field (15) with a second, to the field direction (f_G) the coarsely magnetization field (13) substantially vertical field direction (f_F) magnetized. In the case of the measuring standard is produced in this way, the magnetic saturation of the track at the pole boundary (6) in contrast to the direction of the track (sr) adjacent sections of the pole boundary (6) is reduced.
