Patent ID: 7751991

Claim:
A system for determining the wear state of a machine tool, comprising: a machine tool having a controller; a production control computer; a tool database; and a simulation computer connected to the machine tool controller, the production control computer and the tool database via a respective data connection wherein the simulation computer determines data describing the wear state of the machine tool taking into account real machine manufacturing and tool data via a simulation process and feeds the determined data to a display unit or a further process via the data connection; wherein the data connection is the internet or an intranet; wherein the display unit is part of a computer and the transfer and/or display of the data describing the wear state takes place in response to the inputting of a request signal by means of an operating unit of the computer; wherein the simulation computer carries-out the simulation process via a software API or an executive routine; and wherein the simulation process carries out the simulation via a plurality of simulation modules, which are combined by the simulation computer to form a complete simulation software package wherein the plurality of simulation modules includes at least two of: a module for simple abrasion simulation with a reconstruction of tool paths at a workpiece; a module for carrying out a simulation of a geometric machine tool behavior based on a kinematic simulation; a module for carrying out a simulation of a dynamic behavior of drives and regulating circuits of the machine tool based on a dynamic simulation; and a module for carrying out a simulation of the behavior of the machine tool structure in respect of dynamics of said structure.
