description Automotive body panel quality is imperative, particularly in the automotive industry where radically shortened product development cycle time remains a crucial differentiating factor between the best performing companies and the rest of the industry. Automotive body panel checking processes aim to produce higher quality parts, reduce cost, and achieve higher productivity. Checking fixtures design is required in the automotive parts manufacturing, specifically to check the accuracy of the produced part according to the standard design and reduce the human error by incorporating computer programming. The primary objectives of this thesis were to develop a Portable Checking Fixture Device (PCFD) in order to check the surface accuracy for automotive stamping parts, analyse the surface accuracy of the automotive stamping parts and validate the system of PCFD. The development of a PCFD starts from the design of the gantry system, hardware and software part until the validation of the data.
