Guide to CNC Engraving – Carbide 3D
Engraving is a shallow cut into your part to create fine detail. Engraving is frequently used to add text for personalization or other information, like branding or serial numbers. Engraving can also be used to add markers, measurements, or alignment points to mechanical items. In most cases, engraving is decorative, so it’s more important to make the final part look good than to hit specific dimensions, which gives you a lot of freedom to pick the machine and cutter that will be most productive for you.
Understanding CNC Engraving
CNC (Computer Numerical Control) engraving machines are designed to create precise engravings on various materials, including wood, plastics, and metals. These machines utilize computer-controlled tools to achieve high accuracy and repeatability, making them ideal for both hobbyists and professionals.
