Cutting Technology

One of the most important manufacturing processes for the manufacture of tools and products is machining with a geometrically defined cutting edge. In the machining technology laboratory, the basic process interrelationships are taught using the machining processes of drilling, turning and milling. The effects of the system variables (machine tool, tool, cutting material, workpiece material) and the control variables (cutting speed, feed rate, cutting depth) on the process variables (power, force, heat, temperature) and the effective variables (tool wear, chip shape, workpiece surface and geometry) are investigated. The machining tests can be carried out with the following machine tools:

• 5-axis machining centre with automatic tool change for machining complex workpieces, such as tools for sheet metal working, injection moulds, impellers for turbines, pumps and compressors.
• Production lathe with main and counter spindles and 3 turrets, each turret having 12 driven tool stations. In addition to the usual turning contours, milling operations such as grooves on the workpiece can also be produced.
• NC milling machine with three axes and without automatic tool change. The console milling machine is used for simple milling and drilling operations.
• Conventional column drilling machine with stepless adjustment of the speeds and feeds.
• Tool setting device for measuring the tools used in the NC machines (machining centre, production lathe, milling machine).

In the laboratory, students can acquire and deepen basic knowledge in the field of machining technology through practical experiments.
