The automotive industry is highly competitive. About 30% of global vehicle production originates from China, with Japan accounting for 10%. Worldwide annual production reaches 72 million units, generating thousands of distinct design variations each year.

Given that every vehicle requires at least two headlamps, plus additional lighting (e.g., rear windshield-mounted lights), this article details the prototyping process for automotive headlight light guide strips.

CNC machining strategies for acrylic (PMMA) - covering material selection, fixturing, cutting parameters, and post-processing. Learn how to achieve optical-grade finishes with ≤0.02mm tolerances for applications like light guides, display prototypes, and automotive lighting.
