This case focuses on the aluminum precision component processing project of a high-end American automobile manufacturer, and uses high-speed five-axis CNC technology to achieve mass production of red, orange, and blue multi-color anodized components. In response to the customer's special design requirements for sharp edges, the team uses customized tool path optimization and 3D contour detection technology to perfectly present sharp corners while ensuring structural strength. Combining concurrent engineering with intelligent scheduling systems, the delivery cycle was successfully shortened by 30%, and quality was guaranteed through salt spray testing (≥500 hours) and three-coordinate detection (±0.02mm). The customer highly recognized the innovation and execution efficiency of the solution, and added 5 new parts orders, further consolidating the long-term cooperative relationship between the two parties.
