ROTARY TABLE COMPENSATION

Disclosed is rotary table compensation. The present invention discloses a Coordinate Measuring Machine (CMM) system comprising a CMM, a rotary table, and a rotation arrangement, wherein the CMM system is configured to be calibrated by determining the 6 dof pose of a jig, and to a method for calibrating a CMM system. The jig can e.g. be mounted to the rotary table or to at least one component of the rotation arrangement, such that a current pose of the jig is associated with a current pose of the rotary table with respect to the CMM. The rotary table can be moved into multiple poses, and the 6 freedom of degree pose of the jig is measured for each of the multiple poses of the rotary table. An error map is generated, based on the angles associated with the poses of the rotary table, and is used to generate a coordinate transformation from the CMM coordinate system to the part coordinate system, which is associated with the rotary table, based on the error map.The present invention further relates to a computer
