Optimal Sensor Placement for Thermo‐Elastic Coupled Machine Models

Abstract Accuracy requirements for machine tools demand an accurate positioning of the tool center point. Due to heat sources, example friction and loss motors, a can undergo complicated deformations during operation. While location mounted sources are known in advance, there also process dependent like hot chips after chip off. Furthermore many material parameters most coupling not exactly, or have unknown temperature dependency. We consider coupled thermo‐elastic finite element model simplified tool. include uncertain exchange present optimal sensor placement approach capture sources.
