About

Jingqi Sun is a leading figure in precision measurement and manufacturing metrology, with a primary focus on the kinematic modeling and accuracy enhancement of nonorthogonal coordinate measuring machines. His most cited work, "A Kinematic Model for Parallel-Joint Coordinate Measuring Machine" (2013, 15 citations), addresses a critical challenge in portable coordinate measuring machines (PCMMs)—improving measurement accuracy through advanced structural design, data processing, and parameter identification. This foundational contribution has informed subsequent research in error compensation and calibration techniques for flexible measurement systems. Sun’s research bridges theoretical kinematics and practical industrial applications, offering robust solutions for high-precision manufacturing environments. His work is particularly influential in the development of more accurate and reliable PCMMs, which are essential for quality control in aerospace and automotive sectors. By systematically tackling the mathematical modeling and identification of kinematic parameters, Sun has provided a roadmap for reducing systematic errors in parallel-joint systems. His contributions continue to shape the field of coordinate metrology, making him a respected authority for students and researchers working at the intersection of robotics, precision engineering, and manufacturing science.
