Abstract : Gear form grinding had been applied in gear manufacturing for decades. The relative theories and the mathematical models had also been accomplished very well. However, the profile accuracy of the gear is directly dominated by the wheel profile, which is calculated by the corresponding gear flank. The dressing points of the wheel are determined by the nodes on the gear flank. Usually, the nodes on the gear flank are selected with an equal radial increment about its gear center. In this study, we proposed a method for selecting the nodes on the flank by an equal rolling arc of the involute profile, which is similar to the relative motion in involute gear measuring. To analyze the results, a mathematical model for calculating the error between the theoretical involute and node path which is form by the connecting the nodes with linear sections. We compared the errors of the node paths which are form by the different node-selecting methods, the equal radial increment and the equal rolling arc increment, respectively. The numerical examples show that the nodes selected with an equal rolling arc provide better profile accuracy nearby the gear base circle. However, the nodes with an equal radial increment provide better profile accuracy near by the gear tip circle. Finally, we combined the previous method to get a better and smoother profile error distribution. Keywords - Gear; Involute; Grinding Wheel; Form Grinding; Nodes; Node Path
