Property model based correction of load dependent machine tool deformations (B06)

• Subject Area: Engineering Design, Machine Elements, Product Development ; Mechanics
• Term: from 2011 to 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 174223256

B06 develops a correction approach based on a grey-box model determining the misalignment of the tool center point (TCP) due to thermoelastic mechanisms. During the 3rd phase all findings concerning the ther-moelastic overall error at the TCP and their behavior over the axes lengthes shall be used to derive a reduced application orientated measurement method. This method allows the measurement and correction during the chip removal with coolant. In addition, an approach to correct longterm drift of the model will be investigated.
