摘要：A method of assisted mounting and error compensation for absolute grating ruler comprises: (1) when mounting a CMOS sensor and a grating ruler body, the CMOS sensor reads an upper and a lower sample windows, and due to an angle existing between the grating ruler body and the CMOS sensor, a difference exists between the numbers of the upper and lower sample windows, and by continually adjusting the grating ruler body or the CMOS sensor, the code reading difference minimized so that the angle is zeroed (2) when mounting the grating ruler body and a mechanic housing, it is moved by a fixed displacement in a motion direction, and a grating encoding reading is recorded and an error compensating amount is obtained which serves as error compensation value in an actual motion to correct a cumulative error introduced by the angle between the grating ruler body and the motion direction.
