**7. Conclusions**

A new five-DOF hybrid robot manipulator and two experimental platforms were developed. For this robot manipulator, a new robotic deburring methodology for robotic deburring tool path planning and robotic deburring process parameter control was presented. The major contributions of this article can be summarized as follows:


In future work, several meaningful attempts need to be carried out, such as offline path correction, compensation for vibrations and/or chattering, backlash of ball screws and robot manipulator structural deformations, suppression for high frequency oscillations, and structural rigidity improvement of the robot manipulator. The two proposed methods are expected to provide some insight into the foundational aspects of robotic deburring tool path planning and robotic deburring process parameter control.
