Updatetime: 2021-07-13 11:22View:

Development:

(1)The quality feedback after laser cutting, laser welding and heat treatment is integrated to give full play to the overall advantages of laser processing.

 

(2)With the development of Internet and WEB technology, it is an inevitable trend to establish a web-based network database, automatically determine the laser cutting process parameters by using fuzzy reasoning mechanism and artificial neural network, and to be able to access and control the laser cutting process remotely.

 

(3)The application range of laser cutting robot will be wider and wider as the 3d laser cutting machine develops in the direction of high efficiency, high precision, multi-function and high adaptability.Laser cutting is developing towards the direction of laser cutting unit FMC, automation and automation.

 

(4)With the development of high-power lasers and the use of high-performance CNC and servo systems, the use of high-power laser cutting can achieve a high processing speed, while reducing the heat affected area and thermal distortion;The thickness of the material that can be cut is further improved. The high-power laser can be used by using Q switch or loading pulse wave, so that the low-power laser can produce a high-power laser.

 

(5)According to the influence of laser cutting process parameters, improve the processing process, such as: increase the blowing force of auxiliary gas on cutting slag;Adding slagging agent to improve the fluidity of melt;Increase auxiliary energy and improve energy coupling;And switch to laser cutting with higher absorption.

 

(6)Laser cutting will be highly automated and intelligent.CAD/CAPP/CAM[4] and artificial intelligence are applied to laser cutting to develop a highly automated multifunctional laser processing system.

 

(7)The performance of laser cutting machine can be improved by controlling laser power and laser mode adaptively according to machining speed or building process database and expert adaptive control system.With the database as the core of the system, and oriented to the universal CAPP development tool, the various data involved in the laser cutting process design are analyzed, and the corresponding database structure is established.

Advantages:

(1)No damage to the workpiece: the laser cutting head will not contact with the material surface to ensure that the workpiece will not be scratched.

 

(2)Not affected by the hardness of the material being cut: laser can process steel plate, stainless steel, aluminum alloy plate, cemented carbide, etc., no matter what kind of hardness, can be cut without deformation.

 

(3)Not affected by the shape of the workpiece: laser processing is flexible, can process any graphics, can also cut pipe and other profiles.

 

(4)Can be cut for non-metal processing: such as plastic, wood, PVC, leather, textiles and plexiglass.

 

(5)Save mold investment: laser processing does not need mold, no mold consumption, no need to repair the mold, save mold replacement time, so as to save processing costs, reduce production costs, especially suitable for large products processing.

 

(6)Material saving: the use of computer programming, can be different shape of the product for the whole sheet material cutting, maximize the utilization of materials.

 

(7)Shortens the new product manufacturing cycle: the new product trial production, the quantity is small, the structure is uncertain, may change at any time, cannot give the mold at all, the laser cutting machine greatly shortens the new product manufacturing cycle, reduced the mold investment.

(8)High precision: accurate positioning, high measurement accuracy

 

(9)Slit narrow: the laser beam is focused into a small point of light, so that the focal point reaches a high power density, the material is heated to the degree of gasification, evaporation to form holes.As the beam moves relatively linearly with the material, the hole continues to form a slit of narrow width.

 

(10)Smooth cutting surface: no burr on the cutting surface

 

(11)Fast speed: the cutting speed can reach lOm/min, and the maximum positioning speed can reach 70m/m/n, which is much faster than the linear cutting speed.

 

(12)Good cutting quality: no contact cutting, the cutting edge is little affected by heat, there is basically no thermal deformation of the workpiece, completely avoid the collapse formed when the material punching and shearing, cutting joints generally do not need secondary processing.
