What is the difference between cutting, engraving, scoring, etching, and marking?

Short answer

Cutting separates a part by passing through the material. Scoring traces a shallow line without cutting through. Engraving removes or alters a broader surface area to create text, images, or texture. “Etching” is often used for a shallow surface effect, while “marking” can mean a visible change with little measurable removal, such as a color or contrast change.

Cut, score, engrave and mark shown as cross-sections through a sheet Four cross-sections of the same sheet of material, side by side. Under “cut” the beam passes fully through and the sheet is separated into two pieces. Under “score” a narrow shallow notch is cut into the top surface without passing through. Under “engrave” a broad shallow recess is removed from the top surface. Under “mark” the surface is unbroken and only a band of changed color appears, with little or no material removed. Cut through the material Score shallow line Engrave surface removed Mark color change only
Sorted by the result, not the vocabulary. These five words are not standardized across software and manufacturers — name the result you want, then find the control that produces it on your machine. “Mark” generally means little or no measurable removal.

These terms aren’t used the same way everywhere: labs and laser software apply them differently. The most reliable classroom instruction describes the intended result—through-cut, shallow line, filled surface image, or contrast mark—and then maps that result to the local machine’s controls. Students should confirm the operation in preview before a job begins.
