How accurately can we measure temperatures during grinding? This study compares three techniques for measuring grinding temperatures to estimate energy partition to the workpiece, a crucial factor in manufacturing processes. The investigation uses an embedded thermocouple, a two-color infrared detector, and a foil/workpiece thermocouple under identical surface grinding conditions. The research focuses on experimental measurements of grinding temperatures. The study reveals that all three methods—embedded thermocouple, infrared detector, and foil/workpiece thermocouple—yield comparable temperature responses. These results are consistent with analytical predictions for the same energy partition, enhancing our understanding of the thermal aspects of grinding. The methodology section details the setup and execution of the temperature measurements, ensuring the reliability and validity of the data collected. The comparable temperature responses obtained from different temperature measuring techniques in grinding have significant implications for optimizing manufacturing processes. The findings confirm that different methods can reliably estimate energy partition in grinding, which can aid in improving the efficiency and quality of machined parts.
As a publication in the Journal of Manufacturing Science and Engineering, this paper aligns perfectly with the journal’s focus on advancing manufacturing processes. The research directly contributes to the understanding and optimization of grinding techniques, a key area within manufacturing science. Its detailed comparison of temperature measurement methods provides valuable insights for engineers and researchers in the field.
