Quick Laser 3D Robot Laser Cutting Machines, is a laser cutting machine for multi-angle and multi-directional flexible cutting of metal sheets of different thicknesses by a special fibre laser cutting head, a high-precision capacitive tracking system, a fibre laser and an industrial robot system. It is currently widely used in sheet metal processing, metal processing, advertising production, kitchenware, automobiles, lamps, saw blades, lifts, metal crafts, textile machinery, grain machinery, aerospace, medical equipment, instrumentation and other industries. Especially in the sheet metal processing industry has replaced the traditional processing method, popular with industry users.
Why do 3D Robot Laser Cutting Machines have different cutting quality when cutting the same workpiece? Is it that cutting straight lines or large edges is good, but cutting corners or small holes is much worse, and in severe cases there is scraping? Quick Laser analyzes the following reasons for the problems that occur when users use 3D Robot Laser Cutting Machines improperly.
1. Robot structure reasons
The mechanical structure of the six-axis robot is a six-axis tandem structure, each of the six axes of the reducer has an accuracy error.
When the robot takes a straight path, the six axes have a small transformation angle, so the cutting quality is good, while in the execution of circular trajectory or some need for large angle transformation, the quality will be significantly reduced.
2. Robot torque reasons
The reason why cutting quality varies from one stance to another is because of the force arm and the load, which is different from one stance to another and therefore has a different cutting effect.
Suzhou Quick Laser Technology Co., Ltd. has also developed a solution to this problem.
The 3D Robot Laser Cutting Machines can be adjusted by:
1. Improve the cutting process (cutting material, speed, gas pressure, gas type, etc.)
Generally in the corner of the place robot over the arc vertex stay longer, where the general use of speed reduction, power reduction, real-time adjustment of air pressure, speed reduction in order to reduce robot jitter, power reduction is to reduce overburning, coupled with real-time adjustment of air pressure with real-time adjustment of speed and power, so the corner overburning problem can be very good improvement. If different materials such as carbon steel, stainless steel and aluminium are involved, we can solve the problem of real time adjustment of air pressure for different cutting plates by adding high pressure proportional valves and other related accessories.
2. Work on the tooling
For the specific workpiece to do the right tooling, do not put the tooling on the trip limit position, should be as much as possible in the workpiece cutting path in the robot can “comfortable” cutting position. In addition, for some pipe or hole cutting let the workpiece rotate while the robot stays still or moves less.
3. Adjusting the robot’s stance
The operator should adjust the robot’s stance by “manual teaching”, allocate the angle of rotation of each axis reasonably, and make the robot stance as “comfortable” as possible for positions requiring high precision and as few axes as possible when cutting.
