What Is a Cutting? Essential Guide to Propagation
What Is a Cutting?
A cutting refers to the separation or opening of a physical object into two or more portions through the application of force.
Various implements such as knives, saws, scalpels, and microtomes are commonly used for cutting.
Cutting can be achieved when a sufficiently sharp object, with greater hardness than the material being cut, is applied with enough force.
Liquids, such as through the use of water jet cutters, can also be employed for cutting when applied with sufficient force.
This compressive and shearing phenomenon occurs when the stress generated by the cutting implement surpasses the ultimate strength of the material being cut.
The thickness of cutting edges depends on the hardness of the materials, with thinner edges for cutting soft materials and thicker edges for harder ones.
Cutting metals has been a crucial aspect of manufacturing throughout history, and different methods can be categorized based on the physical phenomenon utilized.
Laser cutting, while not ideal for highly reflective materials like aluminum, is commonly preferred for its efficiency, versatility in producing flat parts, and ability to etch and engrave complex or simple designs.

Did You Know?
1. A cutting is a plant propagation technique wherein a portion of a plant, usually a stem or leaf, is cut and placed in a suitable medium to grow into a new plant.
2. Did you know that the technique of plant cutting dates back over 4,000 years to ancient Egypt, where it was documented as a means of propagating fig trees?
3. Certain plants, such as the Christmas cactus (Schlumbergera), can be easily propagated from a single leaf cutting. This means that an entire plant can be grown from just one leaf!
4. In the Victorian era, plant cuttings gained popularity as a way to express sentiment through the language of flowers. Different flowers and plants held symbolic meanings, allowing people to convey messages through the plants they shared as cuttings.
5. Some plants, like succulents, can grow new roots directly from their leaves when placed in appropriate conditions. This means that you can simply place a leaf on suitable soil, and it will develop roots and grow into a whole new plant.
Introduction To Cutting
Cutting is a fundamental process in which a physical object is divided into two or more parts through the application of force. This force can be exerted by using various implements, such as knives, saws, scalpels, and microtomes.
The key principle behind cutting is that any object, as long as it is sharp enough and exerts enough force, can successfully separate another object into sections.
While we commonly associate cutting with solid objects, it is worth mentioning that even liquids can be used to achieve this phenomenon.
A prime example is the water jet cutter, which utilizes a high-pressure stream of water to forcefully slice through materials. This demonstrates that cutting can also occur through the application of sufficient force with liquid substances.

Implements Used For Cutting
The tools used for cutting vary depending on the material and the desired outcome.
-
Knives, perhaps the most prevalent cutting implement, come in various forms and sizes. They are commonly used for everyday tasks in the kitchen, as well as in industries where precision cuts are required.
-
Saws, on the other hand, are efficient tools for cutting through larger and denser materials, such as wood and metal.
In medical fields, scalpels and microtomes are used for cutting tissues and small specimens with utmost precision. Scalpels are small, sharp blades primarily used for surgical procedures, while microtomes are specialized devices employed in laboratories to thinly slice samples for microscopic examination.
These implements showcase the diverse range of tools available for cutting and their specific applications.
Cutting With Liquids
Although typically associated with solid objects, liquids can also be used for cutting purposes. Water jet cutting is a prime example of this phenomenon. This technique involves the use of highly pressurized water, often mixed with abrasive materials, to cut through various materials. The high velocity at which the water is expelled, combined with the abrasive particles, allows it to effectively slice through materials like metals, ceramics, and composites.
Water jet cutting offers several advantages over traditional cutting methods. It is a cold-cutting process, which means it does not generate heat that can potentially alter the integrity of the material being cut. Additionally, it produces precise cuts without leaving burrs or rough edges. This makes it suitable for a wide range of applications, from aerospace and automotive industries to art and architecture.
Factors Affecting Cutting
Several factors influence the cutting process. First and foremost, the stress generated by the cutting implement plays a crucial role. The stress must exceed the ultimate strength of the material being cut for successful separation to occur. Furthermore, the force applied and the area of contact between the cutting implement and the material are directly proportional and inversely proportional, respectively, to the stress generated.
The thickness of the cutting edges also affects the cutting process. When cutting soft materials, thinner cutting edges are preferred as they require less force to achieve separation. In contrast, harder materials necessitate thicker cutting edges to withstand the higher stress required for effective cutting. Consequently, understanding the characteristics of the material and selecting the appropriate cutting tools are essential for achieving desired results.
Methods And Applications Of Laser Cutting
Metal cutting has a long history in the manufacturing industry, with different methods developed based on physical phenomena. Laser cutting is an advanced technique that uses focused laser beams to make precise cuts on materials.
While laser cutting is effective for a wide range of materials, it may not work well with highly reflective substances like aluminum. The reflective nature of these materials can cause the laser beam to bounce off instead of cutting through. However, laser cutting is excellent for producing quick results and offers customization capabilities, allowing for the production of flat parts and intricate designs through etching and engraving.
In summary, cutting is a versatile process that involves applying force to separate objects. Various cutting tools, such as knives, saws, scalpels, and microtomes, cater to different needs, materials, and precision requirements. The innovative use of liquids, like water jet cutting, demonstrates the expanding possibilities in cutting techniques. Understanding factors like stress, force, contact area, and cutting edge thickness is crucial for achieving optimal results. Finally, laser cutting is a highly efficient method with broad applications, despite its limitations with highly reflective materials.
