Fiber laser cutting machines have become the mainstream processing and cutting equipment due to their fast speed, high efficiency, low cost, safe operation and stable performance. The continuous on-line of its high-performance state is closely related to the setting of the cutting speed of the equipment.

Harm Caused By Improper Cutting Speed
Too fast
- Unable to cut, sparks are spraying randomly
- Cause the cutting surface withstripes, andgenerate melt stain at the lower half of the surface
- Cause roughsection , but no melting stains
Too slow
- Cause over-melting condition, rough cutting surface
- The slit becomes wider and melts in the sharp corners
- Affect cutting efficiency
Factors That Affect The Cutting Speed
Material
The metal materials can be cut by the laser cutting machine include aluminum, stainless steel, carbon steel, copper, and alloy materials. Each material has its own properties, and its absorption rate of laser light is also different, so the cutting speed setting should be different.
Thickness
The thickness of the material is different, the time required for piercing and processing will be different. During the cutting process, the thicker the thickness, the greater the laser energy required and the slower the cutting speed.
Output Power
The thickness of the material is different, the time required for piercing and processing will be different. During the cutting process, the thicker the thickness, the greater the laser energy required and the slower the cutting speed.
How to Set The Cutting Speed
Before metal processing, the machine parameters must be set first. Generally speaking, if the parameters are not set well, there will be problem with the cutting speed. Pay attention to the following two points when setting parameters:
Initial velocity
The initial speed is the speed at which the machine starts, it is not the bigger the better. If the setting is too high, the machine jitter will be very large.
Acceleration
The acceleration affects the time it takes from the initial speed to when the machine normally cuts.
The machine is constantly starting and stopping when cutting different patterns. If the acceleration is set too low, it will slow down the cutting of the machine.
How To Judge Whether The Cutting Speed Is Appropriate
The cutting spark of laser equipment can be used to judge whether the feed speed is appropriate.
- If the spark spreads from top to bottom, it indicates that the cutting speed is appropriate
- If the spark tilts backward, it indicates that the feed speed is too fast
- If the sparks appear to be non-diffuse and small, and condense together, it indicates that the speed is too slow
