5-axis machining is now used by many machining companies and allows machining of a part along 5 axes of motion compared to 3 axes in one setup. While this can be a cost saving factor, 5 Axis machining is used more often for complex contour work, which may need simultaneous movement of all 5 Axes.
Recent advances in software have helped make the conversion from 3-axis and 3+2 axis positioning to simultaneous 5-axis machining accessible to everyday numerical control programmers.
Although some of these techniques might require additional programming time, the benefits of reduced machining, setup time and reduced hand-polishing outweigh the costs.
