We have an Amada 3kW CO² laser with a 3000 x 1500 bed, and use this to cut mild steel, stainless steel, acrylic, and wood components for our own parts and assemblies, and components for the use of our customers.

Most of what we cut goes on for further processing, such as bending, welding, electropolishing and galvanising.  

 

What will help to reduce the cost of my laser-cut components?

Here are few ideas that will help to produce a more economic component.

  1. Reduce the number of pierces.  Each pierce takes time, and therefore costs money.  A couple of ideas for reducing the number of pierces are:
    •  Linking holes, so they are similar to a figure 8.  
    •  Slotting the holes to the outside edge, so the hole is cut as part of the perimeter.  

    These ideas are not always practical, but in some cases will work well.

  2. If cutting stainless steel, consider changing the assist gas type.  Instead of using nitrogen, could Ezi-cut be used? Ezi-cut is made on site from compressed air, and is around 97% nitrogen.  

    Using this option does depend on the end use of your component.  The reality is that the pure nitrogen does provide a cleaner cut, but not all components are visible and need the better finish.

  3. Can a thinner section material be used?  If the design is changed, would a thinner material still be strong enough?  Or is it possible already 'over-engineered', and a thinner section perfectly viable?

    Needless to say, material does cost, and the more there is. . .

  4. If there is further processing, will a design change make this easier or more foolproof, thus reducing costs down the line?
