What Is Laser Cutting?
Understand how laser cutting transforms sheet metal into custom components with detailed contours and precise features.
Laser cutting is a manufacturing process that uses a focused laser beam to cut material along a programmed path. In sheet metal fabrication, it is commonly used to create flat components with defined outlines, openings, slots, and intricate profiles.
Based on a digital design, the cutting path can be programmed to match the part geometry, making laser cutting suitable for customized components without requiring a dedicated cutting die for every design.
From simple metal plates to parts with multiple holes and complex contours, laser cutting offers design flexibility for industrial equipment, enclosures, machinery, and other manufactured products. Material type, thickness, feature size, and dimensional requirements all influence the appropriate cutting process and achievable results.
Advantages of Laser Cutting
Complex Geometries
Create intricate contours, slots, openings, and custom profiles from digital designs, subject to material and feature limitations.
Flexible Design Changes
Programmed cutting paths make design updates easier to accommodate without creating a dedicated cutting die for every geometry.
Repeatable Cutting

Laser Cutting Design Guidelines
Good part design helps improve manufacturability, manage cutting costs, and achieve the required dimensions.
Design Guidelines for Laser-Cut Parts
Designing parts with the cutting process in mind can help reduce avoidable manufacturing issues and support consistent results.
Material Thickness
Select a material thickness that meets the part’s structural and functional requirements. Thickness can influence cutting feasibility, edge quality, processing time, and overall part cost.
Kerf Width
Kerf is the width of material removed during cutting. Account for the cutting kerf when designing narrow features, closely spaced contours, and small openings.
Hole Size and Feature Spacing
Very small holes and narrow slots can be difficult to produce consistently, particularly in thicker materials. Suitable feature dimensions should be evaluated in relation to material thickness and the required tolerances.
Edge Distance
Allow sufficient material between holes or cutouts and the outer edge of a part to help maintain structural integrity and avoid unwanted deformation or damage.
Dimensional Tolerances
Specify tolerances according to the functional requirements of the part. Critical dimensions, mounting holes, and mating features should be clearly identified on the engineering drawing.
File Preparation
Provide dimensioned 2D drawings and, where available, CAD files or DXF profiles. Clearly indicate units, material specifications, thickness, critical dimensions, and any special edge or finishing requirements.
Final design recommendations depend on the selected material, thickness, geometry, equipment, and project specifications.
