Research on the detection and amendment method of the fine processing to propeller of the submarine Kai Mao1, a Peiren Chen2,b and Yumei Sun3,c 1 Department of basic science, Naval aeronautical and astronautical university, Yantai, Shandong, China 2, 3 College of computer and electrical automation, Yantai Nanshan university.
The accuracy of the fine processing of the propeller will be affected by the back lash of the mechanical movement, the inhomogeneity of the material, the nonlinear distribution of the thermal stress and the change of the physical environment condition from the change of time and space of the weariness and cutting of the blade.
