Laser Cutting Process

Laser Cutting Turns CAD Geometry into Flat Metal Parts

Laser cutting is commonly used as the first step in sheet metal fabrication. A digital drawing is converted into a cutting path, then the required profiles, holes, slots, and openings are produced from flat sheet.

The cut parts can later move into bending, welding, machining, hardware installation, finishing, or assembly depending on the drawing.

Basic Laser Cutting Workflow

01 · Drawing Review
Check part profile, holes, slots, material, thickness, quantity, and downstream fabrication requirements.

02 · Cutting Layout
Parts are arranged on the sheet with consideration for geometry, material use, and cutting sequence.

03 · Machine Setup
Cutting parameters are selected according to material type, thickness, and part requirements.

04 · Laser Cutting
The machine follows the programmed path to create the required external and internal geometry.

05 · Part Removal & Inspection
Cut components are removed, checked, and prepared for the next manufacturing step.

What Influences the Cut Result?

MaterialSteel, stainless steel, aluminum, copper, and coated sheet behave differently during cutting.

ThicknessSheet thickness affects cutting speed, heat input, edge condition, and process settings.

GeometrySmall holes, narrow slots, sharp corners, and closely spaced features may need additional review.

Common Materials

● Carbon steel and cold-rolled steel

● Stainless steel

● Aluminum sheet

● Galvanized and coated steel

● Copper and brass where the project is suitable

Why Laser Cutting Is Useful in Sheet Metal Fabrication

● No dedicated cutting die is normally required for the flat profile

● Suitable for custom geometry and frequent drawing changes

● Holes, slots, cut-outs, and external profiles can be produced from the same CAD data

● Cut parts can move directly into bending or other fabrication processes

Typical Laser-Cut Parts

● Brackets and mounting plates

● Enclosure panels and covers

● Chassis and cabinet components

● Battery and energy-equipment parts

● Machine guards and industrial sheet components

Laser Cutting Is Usually the Beginning, Not the End

A laser-cut blank often becomes part of a larger manufacturing route. Depending on the drawing, the next steps may include bending, welding, tapping, CNC machining, hardware installation, powder coating, anodizing, or mechanical assembly.
