Application Cases for Conceptual Design of Mechatronics is authored by the faculty team of Guangxi Technological College of Machinery and Electricity, targeting students in equipment manufacturing and mechatronics related majors at science and engineering colleges, as well as engineering and technical personnel in the manufacturing industry. The textbook focuses on the NX MCD module, guiding students through three stages—foundational, intermediate, and comprehensive application—to master the fundamental principles of mechatronics design and software operation. Emphasizing practical and innovative skills, the book enables students to learn case setup and simulation from simple to moderately complex scenarios. Models are provided by instructors, allowing students to dive directly into the MCD module, with a focus on digital and intelligent design applications.
