The laser cutting system adopts the technical scheme that a lens (3) and a reflecting mirror (1) are mounted right above a workbench (5) in sequence; a laser resonator (19) is mounted on one side of a mirror surface of the reflecting mirror (1); a laser power supply (17), the laser resonator (19), a cooling water device (18) and a numerical control device (15) are connected with corresponding interfaces of a master control computer (16); an auxiliary gas nozzle (4) fixed under the lens (3) is over against the workbench (5); a pattern groove (6) is formed in an upper plane of the workbench (5); a transverse sliding block and a longitudinal sliding block that are fixed on a lower plane of the workbench (5) are mounted in a longitudinal sliding groove and a transverse sliding groove correspondingly and respectively; the longitudinal sliding groove and the transverse sliding groove are fixed in a workbench base (7); and a transverse servo motor (14) and a longitudinal servo motor (9) drive the transverse sliding block and the longitudinal sliding block by a transverse lead screw (13) and a longitudinal lead screw correspondingly and respectively. The laser cutting system and the cutting method have the characteristics that the laser cutting system and the cutting method are environmental-friendly and can improve the cutting efficiency and the cutting accuracy.

Description

technical field [0001] The invention belongs to the technical field of laser cutting machines. In particular, it relates to a laser cutting system and a cutting method for soft material cutting. Background technique [0002] At present, the CO used for cutting soft materials such as leather, clothing fabrics, flexible circuit boards, and soft-based ceramic sheets 2 The power of the laser is in the range of 20~150W (Xiao Hao, on the status quo and development of laser cutting technology in my country, http / / wenku.baidu.com). The laser that requires high precision is a solid-state ultraviolet laser, but this type of laser (Gao Hairui, Development and Application of Ultraviolet Lasers, China New Technology and New Products, 2010.NO8) is expensive. Therefore, how to use the existing small and medium power CO 2 On the basis of the laser, the tooling is improved to further improve the accuracy, which has great practical application value. The advantage of this type of laser c...
