Unlock flawless results when CNC milling acrylic parts. Learn the essential tools, optimal speeds, and troubleshooting solutions to prevent melting and achieve precision.

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.
