Abstract: In the technical field of composite fiber placement, the tool presetting strategy of similar rotation component is a key factor to judge the manufacturing precision and determine the component manufacturing quality. With the help of laser ranging probe setting at the pressure roller of fiber placement head, every tool presetting point and check point can be monitored. With those probe results, the mold manufacturing precision and adjusting precision can be checked. Based on the mold rotation and probed data, aiming at disposable molds with low cost and reusable molds with high precision respectively, this paper put forward the setting method and tool presetting strategy about mold tool presetting points. And, the experiment of S airplane inlet tape laying is carried out to validate the tool presetting strategy. The tool presetting problem of complex similar rotation component can be solved effectively by using this tool presetting strategy.
