Optimizing Punch/Laser Combo Machines for Precision Fabrication

February 10, 2025

As reported by The Fabricator in their article, “Optimizing the Punch/Laser Cutting Combination Machine”, punch/laser combo machines have become indispensable in modern metal fabrication, offering a versatile and automated solution for punching, forming, tapping, and laser cutting. Companies like Special Products & Mfg. (SPM) have refined their approach over the years, leveraging advanced programming and automation to enhance efficiency and run lights-out operations.

The Power of Punch/Laser Combo Machines

Punch/laser combination machines merge the precision of laser cutting with the speed and forming capabilities of punching, making them an ideal choice for complex sheet metal production. Key advantages include:

Automated Tool Changes – Machines can switch between tools from large tool magazines, reducing downtime.
Efficient Part Handling – Suction grippers and chutes streamline the removal of finished pieces and internal cutouts.
In-Process Tapping & Forming – Eliminates secondary operations, improving productivity.

Best Practices for Optimization

Experts at SPM emphasize strategic nesting and toolpath sequencing to ensure process stability and efficiency. Key considerations include:

Balancing Punching & Laser Cutting – Using the right process for the right feature to prevent bottlenecks.
Managing Skeletal Integrity – Ensuring stable material handling to prevent shifting during forming and cutting.
Height-Sensing for Laser Cutting Over Forms – Slowing feed rates to allow sensors to adjust cutting height when working over raised features.

By refining programming techniques, manufacturers can push the limits of punch/laser combo machines while maintaining repeatability and precision.
