The origins of machining can be traced back to the early days of human civilization. Initially, tools were crafted manually using rudimentary technologies. The invention of the wheel and lever marked substantial progress, allowing for the manipulation of materials with greater efficiency. However, it was during the Industrial Revolution in the late 18th to early 19th centuries that machining began to evolve into a more systematic and mechanized process. The advent of steam power and mechanized tools like the lathe and milling machine revolutionized the way materials were shaped and assembled.
