• 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
