A novel tool path generation method for robot milling process

Robot milling process is an important development direction of robot technology, and the automatic tool path generation method is the key step of it. In this paper, an improved CC route method is presented to generate the tool path based on the geometric development platform of Open Cascade. By adjusting the distance of constrain planes dynamically, the inhomogeneous problem of traditional CC method is avoided and the robot milling precision can be improved. Based on the above, a corresponding CAM system is developed. Tool path of rough and fine milling process for free surfaces can be generated through this system. At last, the feasibility and precision of this method are validated by simulation and experiment.
