Abstract

Profile grinding is irreplaceable for the machining of various brittle and hard workpieces such as cutting tools, i.e. milling and boring tools, seal components made off ceramic as well as bearing components. Regarding the required energy for the machining of one volume element, grinding is inefficient compared to other manufacturing processes. By using grinding wheels with a porous metal bond and grains that tend to splinter the process forces can be reduced without influencing the tool wear. This allows for increasing the material removal rate while keeping the process forces on a constant level, ultimately reducing the energy consumption per workpiece manufactured. This paper focuses on the correlation between material removal rate, energy consumption, process temperatures and forces as well as the material removal mechanisms for the profile grinding of cemented carbide.
