The milling centres do not just perform the cutting automatically, but also the changing of tools. During the average process of creating a finished product from a block of metal, for example, various tools are used. So let's see what milling tools are used on the machines and what are the purposes of each.
According to the Altintas, Y (2000) milling is the process in which a cutter is held in rotating spindle, while the workpiece clamped in the table is linearly moved toward the cutter. The factors influence cutting process such as cutting parameters, •rnaterials properties, tools geometry and machine tool workpiece system. It will
When using 2 1/2-D milling or a contour-map approach to do the rough machining, the appropriate selection of tool-path pattern for each cutting layer can significantly reduce rough machining time and hence increase productivity. In this paper, the commonly used toolpath patterns are summarised. A knowledge-based parametric approach for ...

The term "machining center" describes almost any CNC milling and drilling machine that includes an automatic toolchanger and a table that clamps the workpiece in place. On a machining center, the tool rotates, but the work does not. The orientation of the spindle is the most fundamental defining characteristic of a CNC machining center.

– Climb mill with this 2/3's cut ratio. Conventional milling with a face mill causes the chip to start out thin, which sometimes leads to rubbing at the outset of chip formation that is bad for surface finish and can lead to BUE. The best finishes start the chip out fat and then thin it …
Constructive solid geometry is a technique of representing parts by adding and subtracting a set of primitive shapes. Automatic tool paths to machine a part with a rotating cutter are generated by taking the constructive solid geometric description of the part and replacing every primitive shape by an offset primitive, larger or smaller than the part by the cutter radius.
