Definition and Influencing Factors of Cutting Speed

Cutting speed refers to the speed at which a laser cutting machine cuts a material per unit time, usually expressed in length cut per minute (e.g., meters/minute). In the laser cutting process, cutting speed is a key parameter that directly affects the efficiency, quality, and appearance of the final product. Higher cutting speeds can improve production efficiency and reduce processing time, but may also result in a decrease in the quality of the cut edge. Therefore, in actual operation, it is crucial to find an ideal balance between cutting speed and material thickness and type.

There are several factors that affect cutting speed, the first of which is the type of material. Different materials have different thermal conductivities and melting points, resulting in differences in the way they interact with the laser. For example, metal materials usually have high thermal conductivity and require higher laser power and slower cutting speeds to ensure melting and removal. If the speed is too fast, uncut areas may be produced. For materials with lower thermal conductivity, such as wood and plastic, effective cutting can be achieved at higher speeds.

Secondly, material thickness is also an important factor affecting cutting speed. Generally, thicker materials require slower cutting speeds so that the laser beam can fully penetrate and melt the entire material. For low-power laser cutting machines, the speed needs to be slowed down when cutting thicker materials to ensure cutting quality and accuracy.

Another factor that affects the cutting speed is the laser focus. The focus of the laser beam affects the energy density of the cutting. The closer the focus position is to the surface of the material, the better the cutting effect. When the laser beam is optimally focused, a faster cutting speed can be achieved. If the focus is offset, the efficiency of laser cutting may decrease, resulting in a slower cutting speed.

Finally, the feed speed refers to the speed at which the material moves during the laser cutting process. The feed speed and the cutting speed complement each other. A too fast feed speed may cause the laser to not stay on the material for enough time to cut effectively, resulting in incomplete cutting; while a too slow feed speed may cause overheating, burning or excessive melting. Therefore, in actual operation, it is necessary to make comprehensive adjustments based on the material properties and laser parameters to optimize the cutting speed in order to obtain the best cutting effect and quality.

Relationship Between Power and Cutting Speed

The performance of laser cutting technology depends largely on the power of the laser. In theory, there is a positive correlation between laser power and cutting speed, but this relationship is affected by many factors. In practical applications, understanding how laser power affects cutting speed is the key to optimizing cutting efficiency and quality.

1. Theoretical Analysis

The working principle of laser cutting is to heat the material to the melting point through a laser beam to achieve cutting. In this process, the higher the power provided by the laser, the greater the energy input per unit time. Therefore, higher laser power can heat and melt more material in a shorter time, thereby increasing the cutting speed.

Specifically, the rate of laser cutting can be understood by the relationship between the energy input of the laser and the thermal properties of the material. The higher the energy density of the laser focus, the faster the cutting speed. When the laser power increases, the energy density will also increase accordingly, promoting more efficient heat transfer and thus improving the cutting effect. In theory, for every doubling of the laser power, the cutting speed may be increased several times, but this ideal state does not always hold true in practical applications.

2. Performance in practical applications

In practical applications, the effect of laser power on cutting speed can be analyzed from cutting machines of different power levels:

● Low-power laser

Applicable materials: thin paper, acrylic, cloth, etc.

Cutting speed: usually up to 5-10 m/min

In this power range, the cutting speed is relatively fast, which is suitable for small and delicate work, such as art production and sample cutting. However, when facing thicker or harder materials, this power setting is difficult to guarantee the cutting quality, and the cutting effect is easily affected.

● Medium-power laser

Applicable materials: medium-thick wood, leather, etc.

Cutting speed: usually 1-3 m/min

In this power range, the equipment can effectively handle thicker materials. While increasing the power, the cutting speed has decreased, but the cutting quality and depth have been significantly improved, which is suitable for industrial production and more complex cutting needs.

● High-power laser

Applicable materials: thick wood, acrylic, etc.

Cutting speed: usually 0.5-2 m/min

This high-power equipment can cut thick metal materials quickly and efficiently. Although the speed is moderate, high power significantly improves cutting depth and efficiency, making it suitable for heavy industry and large-scale production.

3. Other factors affecting cutting speed optimization

Although laser power has a significant impact on cutting speed, in actual operation, factors such as material type, cutting thickness, laser focus position, and feed speed also play an important role. For example, in the metal cutting process, the thicker the material, the lower the required cutting speed is often required to ensure that the laser beam can completely melt the material. Therefore, the commissioning and operation of the laser cutting machine not only needs to pay attention to the power setting, but also needs to comprehensively consider all relevant parameters to achieve the best cutting effect.

There is a close relationship between laser power and cutting speed. Appropriate laser power setting can optimize cutting efficiency and improve product quality, and understanding the combined impact of these factors can help users make more reasonable choices in actual applications, thereby improving production efficiency.

This phenomenon is especially obvious when processing thin materials (such as paper and thin plastics), and scorch marks may appear on the cutting edge, affecting the appearance quality of the finished product.

● Uneven cutting: Excessive power may cause the laser energy to be too concentrated, resulting in inconsistent cutting depth or rough cutting edges. Uneven cutting not only affects the appearance, but may also cause difficulties in subsequent processing.

● Material deformation: For some materials, rapid heating at high power may cause uneven heating of the material, causing deformation or warping, especially on larger or thinner parts.

2. Best Practice Recommendations

In order to maximize the effect of CO2 laser cutting, users should reasonably adjust the equipment parameters according to specific needs. Here are some best practice recommendations:

● Choose the power appropriately: Choose the laser power appropriately according to the type and thickness of the material being processed. The thicker the material, the higher the power required, but avoid unnecessary excess power.

● Adjust the cutting speed: Test the material cutting speed before test cutting. Properly reducing the cutting speed can ensure that the material is fully melted under the action of the laser and achieve a better cutting effect. At the same time, a stable cutting speed helps to reduce the heat-affected zone and improve the uniformity of cutting.

● Optimize the focus setting: Ensure that the laser beam is correctly focused to achieve the best energy density. For materials of different thicknesses and characteristics, the focal length may need to be adjusted to ensure that the laser cutting can achieve the most efficient effect.

● Regularly maintain the equipment: Keep the laser cutting machine clean, including regularly checking the laser lens and optical components to ensure that they are free of dirt or scratches to maintain cutting accuracy and efficiency.
