A method for fine tuning of a robot program for a robot application comprising an industrial robot, a tool and a work object to be processed by the tool along a path comprising a number of desired poses on the work object, the robot program comprises a number of program instructions containing programmed poses corresponding to the desired poses, wherein the method comprises: defining a fine tuning coordinate system Xft, Yft, Zft, selecting one of said programmed poses pi, calculating said selected pose in the fine tuning coordinate system, producing program instructions for said selected pose in the fine tuning coordinate system, running said one or more program instructions by the robot, determining the difference between the pose obtained after running the program instructions and the desired pose, adjusting the fine tuning coordinate system in dependence of said difference, producing program instructions for said selected pose in the adjusted fine tuning coordinate system Xft&prime;, Yft&prime;, Zft&prime;.

Method for fine tuning of a robot program

A method for programming of a robot application comprising an industrial robot having a robot coordinate system, a tool having a tool coordinate system and a work object ( ) to be processed by the tool. The application is programmed by means of a position-measuring unit ( ) adapted for measuring positions relative a measuring coordinate system (db). The programming method comprises: selecting an object reference structure ( ) on the object, defining a mathematical model for the object reference structure, defining an object coordinate system (o ), providing measurements by the position-measuring unit on the surface of the object reference structure, determining the object coordinate system in relation to the measuring coordinate system (db) by best fit between said measurements and said mathematical model of the object reference structure.
