METHOD AND DEVICE FOR MEASURING A TOOL RECEIVED IN A WORKPIECE PROCESSING MACHINE

摘要

The invention relates to a method for measuring a tool received in a workpiece processing machine, the method having the following steps: providing a contact or noncontact tool sensing device for detecting positional data on the tool and for outputting signals representative of the positional data; providing an evaluation device for receiving and processing the signals and for outputting a tool geometry determined from the processed signals; detecting a sequence of a first number of positional data on the tool and outputting signals representative of said positional data to the evaluation device; processing the signals representative of the first number of positional data in order to obtain a first approximation of the tool geometry; comparing the first number of positional data to said first approximation of the tool geometry and excluding a subset of the first number of positional data depending on a predetermined criterion, in order to obtain a second number of positional data; processing the second number of positional data in order to obtain a second approximation of the tool geometry; and outputting said second approximation of the tool geometry as the tool geometry determined for the tool.
