These include better and more capable machine tools, CNC processors that allow the machine to accurately cut at increasingly higher speeds and feeds, and flexible automation. Some of the latest trends are individual machine or cells, which can perform more than one operation so there is fewer machines or cells and less floor space being occupied. These multi- task machines also provide minimal setup. Many machine tool manufacturers offer robotics and transfer systems to move parts to and from machines. Because of lack of floor space and skilled operators, stand alone robots or integrated gantry systems are used to load and unload parts into these machines.
Integrated automation changes the way operators handle their equipment.
This automation allows an operator to tend multiple machines and keep them going. Another important trend is five-axis machining in which the technology is becoming less expensive and easier to use. These machines maintain an edge in set up time reduction. This rotary movement saves set up time by letting the spindle reach opposing faces of the part in a single set up. It also saves tooling costs by letting a standard milling cutter held at an angle or machine an angled surface that would otherwise require a special custom cutting tool.
