Quality Control of Rough Automotive CV Joints

Automotive CV joints are critical drivetrain components that endure steering forces, torque transmission, and continuous operational loads. Although rough blanks have not undergone final machining, defects such as cracks, material shortage, or surface damage generated during forging, cutting, handling, and pre-treatment can still compromise subsequent machining yields and final component reliability.

In mass production, failing to intercept defects at the rough stage increases subsequent machining and inspection costs, leading to unnecessary process waste. For these magnetizable metal workpieces, MPI can be applied to make cracks, lack of fusion, and near-surface discontinuities visible, which are then interpreted and localized by iEagleAI.
