Sensor integration in a workpiece can be used to characterize manufacturing processes but due to integration, a foreign element is added to the material which can alter its material properties [1]. This can lead to a high order of measurement uncertainty. Additionally, the extent of deviation from standard behavior may vary depending on how the sensors are embedded into the material. This report describes the simulation of the thermo-mechanical stress developed on a sensor-integrated workpiece, ‘sensorial steel’, during surface grinding and compares it with that on a homogenous workpiece.
