With the increasingly fierce competition in the global market, technological innovation is regarded as an important factor for manufacturing companies to ensure their future competitive advantages. Modern mechanical design and manufacturing technology has become the mainstream trend of the machinery industry, and the rise of micro-processing production technology is an unstoppable international trend. Therefore, the machinery manufacturing industry must increase its efforts to develop and update micro-processing production technology and keep up with the pace of upgrading of the machinery industry. At present, most of the processing technology innovation activities are highly dependent on the personal knowledge accumulated for a long time in the previous projects, and the success rate of the innovative methods is low. TRIZ theory (Theory of Inventive Problem Solving) provides a systematic theory and method tool for people to discover and solve problems creatively, due to TRIZ theory is mainly applicable to product innovation design, it lacks specific parameters and principles for process innovation. In recent years, the Computer-Aided Process Innovation (CAPI) introduced on the basis of computer technology provides designers with an effective way to obtain process innovation inspiration and improve process technology innovation efficiency. This paper takes the innovative solution of the micro-turbine machining process problem as an example to verify the effectiveness of the computer-aided process innovation solution method.
