Fiber-laser cutting

CNC laser cutting machines use different cutting methods, depending on the material and working gas, such as reactive cutting, evaporation, and melting. The laser source used can be CO2, solid-state, fiber-optic, or diode.

Fiber laser cutting stands out as the most efficient method for cutting sheet metal parts. Years ago, the method was competitive for processing with laser power sources up to 5 KW, with small thicknesses and working area sizes of 1.5 x 3 meters.
Today, innovations in the design of fiber laser machines significantly impact the technology for processing sheet metal parts. The power of fiber laser sources has increased to ranges between 5 and 60 KW, the working gas is filtered air, the working area dimensions are 2 x 25 meters, and the possible cutting thicknesses for sheet metal parts reach up to 60 mm, and in some cases up to 100 mm. Fiber laser cutting achieves cutting speeds that are multiple times higher than those of plasma cutting.

Due to the high power of the laser beam - 15, 30, 60KW and the high cutting speed, a large amount of heat during cutting is “blown away” with the melted metal in the cut, and the thermal deformations in the workpiece are an order of magnitude lower than all previously used thermal cutting methods. If with plasma cutting on a cutting layout the linear elongations in a 12m sheet were from 5 to 10 mm, now with high-power fiber laser cutting they are less than 1 to 2 mm.

Following the innovations in CNC machines for fiber laser cutting, NESPERT CAM has further developed and included distinctive features:

-Cutting with common cut of matrices of rectangular details in a "ladder" scheme, including with spikes,

-cutting according to the scheme "Processing to the material",

- programming with real kerf and combined control of the offset of the paths from the part’s contours,

- working with usable remnants,

- nesting orders preparation with NESPERT Manager,

- pricing and offering by orders for true shape nesting production,

- Interactive creation of technology and processing route/order for parts on the sheet without technology, with automatic creation of technology for internal and nested trajectories.

The process of generating NC programs now allows programming of machines operating with the XML LXD format used in Chinese laser cutting machines.

Functionality for working with products has been added to NESPERT Manager.

In NESPERT NCV, NC programs are verified in ISO/EIA, ESSI, XML LXD, and other formats.

NESPERT CAM nests on whole sheets and/or usable remnants. It programs various types of laser processing – cutting, engraving, vaporizing.
