Ceramic cutting tool materials have to resist high thermal loads during the cutting process. These thermal loads are acting in the form of thermoshocks. To investigate the role of these thermoshocks, it is necessary to find a method which enables a simulation of thermal loading (in the form of thermoshocks) but which excludes mechanical loads. This kind of simulation is possible by laser beaming, because a laser can provide extremely short and strong thermoshocks which cannot be realized by any other method. Different ceramic cutting tool materials were investigated with this technique of thermal load simulation. The role of the load function (amplitude, frequency, load cycle) concerning the wear behavior was estimated. In addition, calculations were carried out to calculate the internal temperatures in ceramic tool tips caused by simulation tests.
