Facing the challenge of industry 4.0, the level of tool machinery must be promoted. Aesthetic appearance plays a crucial role in exhibiting the level of a machine. This paper introduces the grey-based Kansei engineering scheme in conjunction with an innovation process to provide a complete design process, from concept formulation to prototype making, so as to add the additional value of a machine. In this study, a computer-numerical-control (CNC) machine is chosen as the target since it ranks as high as the 3rd biggest enterprise in Taiwan. The CNC machine products in the marketplace were analyzed in two aspects: form decomposition and descriptive words. Then the Multiple Regression and Grey System Theory were applied to establish their relationship. Based on this relationship, the weight of each form element on a prescribed descriptive word can be obtained and used as design reference. With this reference, an image board of creativity can be established. A final innovative product form can be obtained by extracting the idea from this image board. Furthermore, a verification was performed and a satisfying result of the proposed Kansei-innovation manipulation procedure was obtained.
