In view of all sorts of questions existing in CNC machining, such as machining vibration, so proposed a new method of free-form surface NC machining path optimization based on constant scallop height. This method first discrete surface boundary into the knife touch point based on the maximum tolerance, then in accordance with the maximum allowable scallop height generates circular trajectory with the same scallop, and finally connects adjacent curve path using the diagonal to achieve a continuous cutting scallop height tool path. This method can reduce the number of tools cut in and out parts, reduce the processing vibration and tool wear, and the surface processed has the same precision. This method has simple calculation, suitable for free-form surface of CNC highspeed and precision machining.
