When low-cost CNC machines first started becoming popular in everyday engineering workshops back in the 70s a revolution took place. Before, most engineering was manual. There was a man for every job... a man for grinding, a man for milling etc., the unions were not pleased.
There was major concern for the loss of jobs that this amazing technology would cause. But CNC engineering became normal and it didn't matter what the unions thought.
The machines have advanced along with technology over the years. 5 axis machines are common place and there's not a single paper tape CNC machine in sight!
With the micropressor, CNC precision engineering advanced and now anyone can get a machine, put it in a workshop and call themselves a precision engineer.
