System and method for detecting and correcting laser-cutting distortion

A system for generating a G-code for controlling an operation of a laser-cutting machine to cut parts from a sheet of material, upon receiving cutting data specifying a cutting order of parts and a cutting order of edges of each part, tests the parts for potential distortions and generates a G-code to avoid the potential distortion. For testing a current part, the system detects a potential distortion when the final edge of the current part is adjacent to an edge of a previously cut part scheduled for cutting before the current part according to the cutting order of parts. The system modifies the cutting order to select the modified cutting order for which the final edge is not adjacent to any edge of any previously cut part.

Laser nanomachining device and method

According to one aspect, the invention relates to a device (1, 2, 3) for laser nanomachining a sample made of a material having a given transparency band, the device comprising: a focusing module (203, 703) allowing a nondiffracting beam (210, 710) to be generated, along a focusing line generally oriented along the optical axis of the focusing module, from a given incident beam; first means (202, 702) for emitting a first light pulse (I.sub.1) of spectral band comprised in the transparency band of said material, able to generate in said material, after focusing by said focusing module, a plasma of free charges along said focusing line via multi-photon absorption, thus forming a plasma channel; and second means (202, 702) for emitting at least one second electromagnetic wave (I.sub.2) of spectral band comprised in the transparency band of said material, which wave(s) is/are intended to be spatially superposed on said plasma channel in order to heat said material via absorption by the free charges of the plasma.

20180264595 · 2018-09-20 · ·

Apparatuses include a laser cutter positioned within an enclosure that is capable of cutting printed sheets; however, this cutting produces debris made up of airborne dust of the sheet material and marking material. An air duct is capable of drawing an air stream of air and the debris out of the enclosure. A dispenser is positioned within the air duct where the air duct connects to the enclosure. The dispenser is capable of dispensing a dry powder of calcium carbonate into the air stream. The dry powder attaches to the debris. The combination of the dry powder and the debris forms waste, and a filter device (that is connected to the air duct) filters the waste. The filter device is capable of separating the air from the waste, to collect the waste and release the air free of the waste to areas outside the filter device.
