Manual machines are tools that require human effort to operate, rather than relying on electricity or automation. Examples include hand drills, saws, and lathes. These machines are often used in woodworking, metalworking, and other crafts, allowing users to have direct control over their work. Using manual machines can enhance skills and craftsmanship, as they require precision and attention to detail. They are often favored for small-scale projects or in settings where power sources are limited. Additionally, manual machines can be more affordable and easier to maintain compared to their automated counterparts.
