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

点击翻译按钮获取中文摘要

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.
