Abstract：In recent years，social economy has developed rapidly，and the level of science and technology has been greatly improved. Mathematics is the basis of the development of science and technology. It has been applied to scientific and technological research，data analysis，economic and financial， mechanical design，military，astronomy and art and other fields. It has provided powerful guarantee and technical support for the development of national science and technology. With continuous specialized research，people’s understanding of mathematics has made breakthrough progress. Mechanical design must use a large number of mathematical methods to calculate huge data，and ultimately get scientific，effective and accurate research results. Curve fitting is the most commonly used mathematical method in mechanical design. Mechanized operation is the inevitable trend of the development of the times. In this paper，the application of mathematics in the field of industrial machinery is analyzed by taking the design of cam for mechanical parts as an example. The design process of cam for mechanical parts and the concept and method of curve fitting are introduced，and the application of curve fitting mathematical method in mechanical design is discussed.
