Create a Clean Pierce Point That is the Same Diameter as the Cut Width

This feature is important in cutting medical devices, electronics and fine mechanics components from thin materials with features that are too small to allow for piercing the drop-out scrap portion of the material.

Cutting Corners: The Idea Behind Power Ramping

A cut made without the power ramping feature. Power ramping is typically meant to be used when cutting with air or nitrogen in thinner materials that are 3 mm (0.12 in) thick or less. The best applications are in thin to mid-range material when nitrogen is used as the assist gas to increase the edge quality when cutting large contours. The power ramping feature is not as beneficial when cutting with oxygen because of changes to the properties of the assist gas and the decreased feed rates that occur.  
Although power ramping has proven to be highly beneficial, it is often underutilized on the shop floor because fabricators either do not understand its benefits or they just don’t know how to use it. By simply applying the given values and principles presented here, they will see a visible improvement in corner and radii cut quality.

Lasers Handle Cutting and Welding of Complex Parts

The Morgan 3 Wheeler car build in the Premier shop, which used AutoForm simulation to arrive at the 2D shape for each blank, which was then laser cut ready for forming. The shop produced 1,500 sets of bodywork panels at the high speed of laser cutting to keep costs down.
This shop welded the seam and cut 100 million holes in 12,100 torches – in six months. That's not all. Check out the automotive parts they're making.

Laser Marking 101

Laser marking a bevel gear. Lasers have a number of advantages over traditional inkjet printing, etching, mechanical engraving, and stamping. They can mark a wide array of materials, from ferrous and non-ferrous metals to organic materials such as thermoplastics and elastomers, with high marking quality and speeds, minimal effect on material, consistent results, and no tool wear. 
How do you choose the appropriate laser for your marking applications? Here are several factors that must be considered and how they impact the end results.

A High Fiber Diet

The Optiplex Fiber II 6 kW fiber laser cutting system from Mazak Optonics offers superior edge quality, more stable cut performance and greater throughput for processing stainless steel, copper, brass, bronze, aluminum, hastelloy, inconel, titanium, thin gage mild steel, and other exotic metals. There is no need for additional surface cleaning when painting mild steel cut with nitrogen. 
Fiber laser cutting systems are sweeping through metal fabrication shops because they are faster, more consistent, more cost effective, and more competitive.

Fiber Lasers Process Large Sheets Quickly and Economically

The Phoenix FL 6020 fiber laser cutting machine achieves superior cut quality through an advanced cutting head design that allows automated adjustment of focus position and focus diameter, known as “zoom focus.” To achieve the highest possible speed in every material thickness, focus position and diameter are automatically controlled and adjusted by the CNC controller. This advanced technology makes the Phoenix FL one of the most flexible fiber laser cutting machines available today – able to cut different sheet thicknesses with high productivity and excellent cut quality.
Phoenix FL 4020 and 6020 laser cutting systems from LVD Strippit handle sheets up to 240 in x 80 in of both thin and thick materials in standard steels and non-ferrous materials.

FABTECH 2016: Forming & Fabricating

Booth C-22092: The Fiessler AKAS 3-P from Press Brake Safety is the first co-moving press brake safety system to provide high speed operation up to the clamp point. The operator's hands or fingers are protected by the presence of the 3D safety laser beam grid located beneath the ram.
Take a closer look at some of the metal forming and fabrication technologies that will be exhibited November 16-18 on the show floor in Las Vegas.

Sophisticated, Highly Flexible Fiber Laser Cutting

Booth C-25047: Processing different materials and thicknesses in sequence without stopping production and with setups occurring in masked time, the L3-30 fiber laser cutter from Salvagnini uses an air-cooled cutting head with adjustable optics to make solid, clean and reliable cuts on both thin and thick materials, with no contaminants to obscure the lens.
