Across precision manufacturing, in fact, teams widely use it as a safer alternative to glass and brittle plastics for safety guards, optical windows, and industrial structural parts. That said, PC reacts very strongly to cutting heat, and rushed or unoptimized machining often causes issues like melting, sticky tool residue, hidden stress cracks, and cloudy surface finish. For this reason, it demands more careful process control than most standard everyday plastics. In this guide, we break down the full CNC machining system, parameter selection logic, surface finishing [&hellip;]"}
