For centuries, mankind has relied on their own hands and will power to do the work. By using these hand tools, mankind were able to cut, mold, and shape materials needed for various of projects, wants, and needs. Such needs included, for example, cooking utensils, wagons, ships, furniture, and many other products.
Then after the Industrial Revolution, which started in the late 18th century, mankind invented machines to do the work for them. Such machines included lathes, shapers and planers, drilling machines, milling machines, grinders, power saws, and many more. Although the first metalworking lathe was invented in the early 1800s by Henry Maudslay, and the first milling machine in 1818 by Eli Whitney, it was not until the late 1950s when a man named John T. Parsons was given the job of running the first design crew. They were in charge of designing for the modern CNC machines.
Then in the early 1960s, the price of machines dropped to the point where other industries were able to invent machines to help them do the work too. These machines used direct current electric drive motors to make the hand wheels spin or rotate. This made it easier to operate the tools. Not only was it easier, but it also enabled mankind to produce faster. This increased speed enabled them to produce more at any given time, allowing the companies to make and sell more than they ever could before. Over time, more new and improved machines will be invented to make the job easier on us.
