Milling Machines A milling machine is a power driven machine that cuts by means of a multitooth rotating cutter. The mill is constructed in such a manner that the fixed workpiece is fed into the rotating cutter. Varieties of cutters and holding devices allow a wide rage of cutting possibilities.
structure design of machine tool made with artificial granite material. In order to gain insight into the proper and optimized configuration of the milling machine, the FEAs were performed to assess static and dynamic char-acteristics of the milling machines with cast iron and granite composites, respectively, for comparison. With
induced vibrations of the whole machine structure, which are called chatter vibrations or chattering. As a result of the milling process every milling machine is deformed by the cutting forces. The grade of deformation is dependent on the static and dynamic stiffness of the structure of the milling machine.
