|Cutting by Milling - Course: Techniques for machining of material. Trainees' handbook of lessons (Institut für Berufliche Entwicklung, 17 p.)|
By cutting by milling we understand the cutting of workpiece of different geometrical forms (prismatic, rotationally symmetrical) with a metal slitting saw blade as the milling tool.

Moreover, we can cut workpieces being processed before in a strip shape or bar shape. For example, collar-shaped rotationally symmetrical workpieces can be cut into segments by cutting by milling. Sleeve-shaped workpieces can be applied by cutting by milling (semi-sided) as fixing bushes.

The processing and manufacturing of workpieces by cutting by milling is carried out for the purpose:
- to cut strips, bars, collars and sheaves of different geometrical forms and different raw material.
- to cut bushes (semi-sided) in order to reach the clamping of the male part in the bush.

- to cut (to notch or to cut out) certain parts for workpieces, such as angle strips where blacks should be bent off.

The processing and manufacturing of workpieces by cutting by milling is mainly carried out on horizontal milling machines. In special cases cutting by milling is carried out on a vertical milling machine.
That machine is applied especially if the geometrical form of the workpiece or the part to be processed needs a vertical milling machine to be applied.
