My module was on CNC Machines. The "CNC" stands for Computer Numerical Control. These machines were built in the 1940's and 1950's. They were created because people felt like buying parts for this machine to make items would be better than paying people to do that. This really didn't leave some people jobless because we still needed people to enter the codes for the machine to start its job. Some of the machines are operated of a computer and others you can operate of its self. Dealing with this module you have to learn codes and know exactly what your doing. If you have no idea how to operate or enter the different codes you will have a very difficult time. Only a few jobs to operate these machines so its very limited. I also read that since the machines are doing a very good job with building and creating that their thinking about making more of them for different uses.
