Abstract
A method for compensating thermal displacements is carried out on a machine tool having a worktable for mounting workpieces to be machined, and having a tool spindle which can be traversed relative to the worktable on at least one axis and into which it is possible to clamp tools with the aid of which a machining process is carried out on the workpieces. In this case a calculating rule is used to calculate from at least one temperature value currently measured at a measuring point on the machine tool at least one correction value for the at least one axis. The calculating rule is tuned in this case to the respective machining process.
