Abstract
Currently, the bike frame quality check (QC) mostly relies on human operation in industry. However, some drawbacks such as it being time-consuming, having low accuracy and involving non-computerized processes are still unavoidable. Apart from these problems,measured data are difficult to systematically analyze for tracking sources of product defects in the production process. For this reason, this paper aims to develop a 3D geometry mathematical model suitable for bicycle frames QC using robotic arm-based measurement. Unlike the traditional way to find coefficients of a space sphere, the proposed model requires only three check point coordinates to achieve the sphere axis coordinate and its radius. In the practical work, the contact sensor combined with the robotic arm is used to realize the compliance items measurement in shaft length, internal diameter, verticality, parallelism, etc. The proposed model is validated based on both mathematic verification and actual bike frame check.

Bike riding has become a popular leisure sport around the world. For this reason, analysts forecast that the global high-end bicycle market will grow with a compound annual growth rate (CAGR) of 4.82% during the period 2017–2021 according to the report from Research and Markets. The check items of bike frame for quality evaluation mainly include the shaft length, internal diameter, verticality, and parallelism located in different shafts. The proposed mathematical model provides the solutions for checked point coordinate calculation.
