Laser cutting system and laser cutting supplementing method

Abstract

The invention discloses a laser cutting system. The laser cutting system comprises a storage unit used for storing a DXF drawing file and a supplementing processing file, a display unit used for displaying the DXF drawing file and providing an interface for clicking a to-be-supplemented piece and a menu for generating a supplemented piece processing file instruction for a user, and a control unit; the control unit comprises a read-in module used for reading in the DXF drawing file, a calculation module used for extracting point coordinates from a line of the to-be-supplemented piece to form a first coordinate set after receiving the instruction for generating a supplemented piece processing file, calculating vertex coordinates of a lower left corner of a minimum envelope rectangle of the to-be-supplemented piece and calculating a second coordinate set obtained after translating the point coordinates in the first coordinate set to a lower left corner of a coordinate system, a program generation module used for generating a supplementing processing file according to the second coordinate set and an operation module used for operating the supplementing processing file. A plate is placed at the lower left corner of the coordinate system, a laser cutting head directly cuts the supplemented plate at the lower left corner of the coordinate system, a user does not need to find the position of the to-be-supplemented piece, and the idle running time of the laser cutting head is shortened.

Description

technical field [0001] The invention relates to the field of laser cutting, in particular to a laser cutting system and a laser cutting feeding method. Background technique [0002] During the laser cutting process, it is often encountered that the cut individual parts are lost and need to be replaced. There are two methods for feeding the traditional CNC laser cutting system: (1) re-edit the drawing offline, keep the parts that need to be fed, delete other parts on the drawing, and then translate the parts that need to be fed to the origin of the coordinate system and save them. Then import the graphic file into the laser cutting system to start processing supplementary parts; (2) On the laser cutting system, enable the function of only processing the selected graphics, and then click on the parts that need to be supplemented to start processing, the laser cutting head will first start from the origin position Move to the position of the workpiece and start machining. The...

Problems solved by technology

The first solution needs to redraw and arrange the original drawings, and the feeding time will be greatly increased

For the second option, since the part can only be processed at the original position, the operator needs to hold the plate to be replenished (such as the remaining material generated during production) and slowly search for the corresponding workpiece to be processed on the actual machine. And put the plate well, then the laser cutting head needs to move to the position of the part first, and then start the processing, the path of the cutting head running empty will be longer, which increases the feeding time
