Abstract: The herein proposed invention relates to mechanical engineering. The essence of the invention resides in the fact that a contrivance for setting the table position includes two disks provided with drives for moving the table in a horizontal plane and disposed eccentrically one above the other as to be free to rotate about their pivot pins, the upper disk being rotatably mounted with respect to the pivot pin of the lower disk. The pivot pin of the lower disk mounts one device for reading the length of table movement in a horizontal plane along one of the coordinate axes, and a pin is fixed in position on the upper disk a distance from its axis equal to the amount of eccentricity between the pivot pins, the pin being movably associated with the table so as to carry another device for reading the length of table movement in a horizontal plane along the other of the coordinate axes.

Abstract: A device and method for locating a point with preset coordinates x and y in an orthogonal system of coordinates with an X and a Y axes. The device has a planetary train kinematically connected to a mechanical arm via a single four-link parallelogram. The mechanical arm is kinetically connected to another four-link parallelogram. The planetary train is provided with a body and a carrier having a rotation axle pivotally secured in the body. The axle provides a center of the orthogonal system of coordinates around which is moved, through an angle .beta., is a point which is a base point for locating a sought-for point with preset coordinates x and y in the orthogonal system of coordinates. The planetary train further includes a satellite gear rigidly connected to the carrier rotation axle and has its own rotation axle that serves as a center of an angular turn, through an axle .alpha. of a point which represents the base point.
