    Multiaxis machining is a manufacturing process where computer numerically controlled tools that move in 4 or more ways are used to manufacture parts out of metal or other materials by milling away excess material, by water jet cutting or by laser cutting. Typical CNC tools support translation in 3 axes; multiaxis machines also support rotation around one or multiple axes.

    There are now many CAM (computer aided manufacturing) software systems available to support multiaxis machining including software that can automatically convert 3-axis toolpaths into 5-axis toolpaths.[1]

    Multiaxis machines offer several improvements over other CNC tools at the cost of increased complexity and price of the machine:

    The amount of human labor is reduced, if the piece would otherwise have to be turned manually during the machining.
    A better surface finish can be obtained by moving the tool tangentially about the surface.
    More complex parts can be manufactured, particularly parts with curved holes.

    The number of axes for multiaxis machines varies from 4 to 9.[2] Each axis of movement is implemented either by moving the table (into which the workpiece is attached), or by moving the tool. The actual configuration of axes varies, therefore machines with the same number of axes can differ in the movements that can be performed.

    Milling is the machining process of using rotary cutters to remove material[1] from a workpiece advancing (or feeding) in a direction at an angle with the axis of the tool.[2][3] It covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations. It is one of the most commonly used processes in industry and machine shops today for machining parts to precise sizes and shapes.

    Milling can be done with a wide range of machine tools. The original class of machine tools for milling was the milling machine (often called a mill). After the advent of computer numerical control (CNC), milling machines evolved into machining centers (milling machines with automatic tool changers, tool magazines or carousels, CNC control, coolant systems, and enclosures), generally classified as vertical machining centers (VMCs) and horizontal machining centers (HMCs). The integration of milling into turning environments and of turning into milling environments, begun with live tooling for lathes and the occasional use of mills for turning operations, led to a new class of machine tools, multitasking machines (MTMs), which are purpose-built to provide for a default machining strategy of using any combination of milling and turning within the same work envelope.

    see milling machines in action making part, and vote it guys

    to work in industrial This is a very open , mechanical engineering graduate , still needed at all
