The tool, called fresa, possesss multiple edges (teeth) cutting that they remove, to each rotation, a small amount of material in the form of cavacos. For the fact of tool and part if to put into motion in more than a direction at the same time can be gotten surfaces with almost any orientation. The cavacos are relatively small; The thickness of the cavaco is changeable. In the fresamento it has two movements if to consider: Rotation of the tool; Advance of the part (in some cases the tool can execute the two movements).
The machine-tool in which the fresamento is made is called fresadora or machine of fresar. The movement of advance is, generally, made for the proper part that is being usinada. Operation of fresagem: The operations carried through in the experiment had been: Fresadora the machine used tool to make the fresagem is the fresadora. Body: It is a species of carcass of casting iron, strengthened base and generally of rectangular format in which the machine is supported. It supports the too much agencies of the fresadora. Table: It serves of support for the parts that go to be usinada and that they can directly be mounted on them, or by means of setting accessories. Thus, the table is endowed with grooves that allow to lodge the setting elements. Transversal car: It is a structure of casting iron of rectangular format on which it slides and it turns the table in horizontal plan. In the inferior base, the transversal car is connected to the support of the table by means of guides.
