It is the width of material removed during a cut. Knowing it helps correct dimensions and improve the fit between parts.

Understanding the terms also improves the result.
Short, practical definitions for laser cutting and engraving. This first version covers the basics and will grow with new entries on specific topics.
Kerf compensation
It is the correction applied to a path to account for material removed by the laser and achieve the intended final dimension.
Focus
It is the position where the beam is properly concentrated on the material. Incorrect focus can affect the width and quality of the cut.
Power
It is the energy level applied by the laser during an operation. It works together with speed, material and other process variables.
Speed
It describes how fast the head or beam moves during cutting or engraving. Its effect also depends on power, material and the machine.
Passes
It is the number of times a path is repeated along the same route. Multiple passes can complete cuts that cannot be made in a single pass.
Vector
A geometric representation based on lines, curves and shapes. It is commonly used for cutting paths, marking and technical design.
Raster
An image made of pixels. In laser work it is often used for engraving images or filled areas, depending on the workflow.
SVG
An XML-based vector format. It can preserve shapes and dimensions, but you should always check units and scale before fabrication.
