With the rapid development of science and technology and the continuous breakthrough of laser technology, the 5-axis section steel laser cutting machine on the market is becoming more and more popular in the steel structure market. However, for many customers, how to distinguish between true and false 3D 5-axis laser cutting machines is a headache.
This article will focus on the 5 axis section steel laser cutting machine, hoping to be helpful to you.
True vs. Fake 5 Axis Section Steel Laser Cutting Machine
What Is 5 Axis Section Steel Laser Cutting Machine
A true five-axis machine tool refers to a machine tool with the RTCP (Rotation Tool Center Point) function. This function can automatically calculate the mechanical coordinates based on the swing of the spindle and the rotary table. When writing a program, you only need to consider the coordinates of the workpiece, without considering the swing of the spindle and the position of the rotary table.
Fake five-axis machine tools only have the indexing function, and they cannot perform RTCP operations. Although fake five-axis machine tools can achieve the linkage movement of five axes, multiple coordinate settings are required during programming to achieve indexing processing.
Is there RTCP Function?
- 3d 5-axis laser cutting machine has it
- Fake 3d 5-axis laser cutting machine has it
Different Programming Methods
After using the RTCP mode, the 5-axis section steel laser cutting machine can directly operate the tool tip during programming without worrying about the center of the rotating spindle head, which makes programming simpler and more efficient.
If the 5-axis section steel laser cutting machine must rely on CAM programming and post-processing technology, the tool path must be planned in advance; if the 5-axis machine tool is used, the programming will become very complicated and debugging will be more difficult.
Differences in Nesting Methods:
Can support international standard G codes, so it can adapt to a variety of nesting software
Does not support international standard G codes, can only rely on a single nesting CAM software
Different Application Ranges:
Adaptable to various types of steel, different sizes and specifications; Adaptable to special types of steel; H-shaped steel, channel steel, angle steel, variable diameter beam, crane beam, longitudinal beam, widened beam, etc.
Currently only suitable for H-shaped steel; and the tool path for cutting H-shaped steel of different specifications and sizes needs to be re-planned, and there is a risk of collision with the gun.
Is it Suitable for Groove Cutting?
Not only suitable for web grooves and flange grooves, but also for positive grooves, reverse grooves and parallel grooves, and the groove angle can be set arbitrarily.
Currently only suitable for flange grooves of H-shaped steel; the accuracy of different groove types and angles cannot be guaranteed
Difference in Cutting Accuracy:
R-angle cutting and bevel cutting use the RTCP function, true five-axis linkage, to ensure that the positional relationship between the tool tip and the workpiece remains unchanged, ensuring cutting accuracy.
The fake five-axis cannot keep the relative position between the tool tip and the workpiece unchanged through the RTCP function, and can only be calculated and compensated by external CAM software, resulting in loss of cutting accuracy.
Safety
The positional relationship between the tool tip and the workpiece remains consistent during the cutting process, and there will be no collision with the gun (especially during R cutting);
At the same time, the RTCP function ensures that the light direction of the laser cutting head always points to the workpiece, ensuring that the laser always hits the workpiece, and there will be no uncontrollable laser emission direction.
Gun Collision Often Occurs During R-angle Cutting and Bevel Cutting;
During the posture change process, either the gun collision occurs, or the gun is lifted to a higher and farther safe area and then the posture is changed, reducing the cutting efficiency, or there is an uncontrollable or unpredictable safety risk of laser emission direction.
