Compression means keeping the same ideas but conveying them in fewer words.

Compression involves reducing the dynamic range of audio signals to make quieter sounds louder and louder sounds softer. Cutting involves reducing specific frequency ranges or frequencies from an audio signal to reduce certain frequencies or instruments in a mix. While compression affects the overall dynamics of a signal, cutting affects the frequency content.
Compression makes the content denser, whereas cutting removes content.
When an object is cut in half, the temperature remains the same because cutting it does not add or remove heat from the system. The heat energy within the object is distributed evenly, so cutting it does not affect the total amount of heat energy present. Heat transfer occurs when there is a difference in temperature between two objects, so cutting an object in half does not alter its internal temperature.
Friction between the cutting tool and the wood generates heat that softens the wood fibers, facilitating the cutting process. It also provides resistance against the cutting tool, allowing it to maintain contact with the wood and produce cleaner cuts. Proper lubrication or reducing friction can help in achieving smoother cuts and preventing overheating.
The main cutting forces involved in orthogonal cutting are the cutting force (Fc), the thrust force (Ft), and the radial force (Fr). Fc is perpendicular to the cutting edge and is responsible for the material removal. Ft is parallel to the cutting edge and is needed to overcome the resistance of the workpiece. Fr is directed towards the center of the cutting edge and helps stabilize the cutting process.
The optimal plasma torch temperature for cutting through thick metal sheets efficiently is typically between 25,000 and 30,000 degrees Fahrenheit.
A sickle is a small, curved blade typically used for harvesting small crops like grains, while a scythe is a large, long-handled tool with a curved blade used for cutting large areas of grass or crops. The scythe has a longer handle and a larger blade compared to a sickle.
