For maintenance or environmental protection requirements in marine engineering,it needs to complete a certain underwater cutting,and the operation can be done with a wire saw.Underwater wire saw is a flexible grinding cutting machinery,which can cut a variety of materials and has clean and environmentally friendly features.Proper cutting parameters are the prerequisites for ensuring safe and efficient work.The influencing factors of wire saw in the cutting process were analyzed,based on quality function configuration,Euclid norm analysis method was introduced,and several sets of the wire saw machine cutting parameters were studied to obtain reasonable cutting parameters.The result is experimentally proved,which provides a theoretical basis for wire saw efficient work.
