Laser beam cutting (milling)

 •        A laser spot reflected onto the surface of a workpiece travels along a prescribed trajectory and cuts into the material.

•        Continuous-wave mode (CO2) gas lasers are very suitable for laser cutting providing High-average power, yielding high material-removal rates, and smooth cutting surfaces

Advantage of laser cutting

 •        No limit to cutting path as the laser point can move any path.

 •         The process is stress less allowing very fragile materials to be laser cut without any support.

 •        Very hard and abrasive material can be cut.

 •        Sticky materials are also can be cut by this process.

 •        It is a cost effective and flexible process.

 •        High accuracy parts can be machined.

 •        No cutting lubricants required

 •        No tool wear

 •        Narrow heat effected zone

Limitations of laser cutting

 •         Uneconomic on high volumes compared to stamping

 •         Limitations on thickness due to taper

 •         High capital cost

 •         High maintenance cost

 •         Assist or cover gas required
