The monitoring of the cutting temperature field in the cutting zone is an extremely difficult issue, especially when temperature measurements at and near the tool-chip/work interface are concerned. In this paper, an approach is presented by which micro thin film thermocouples (TFTCs), embedded into Polycrystalline Cubic Boron Nitride (PCBN) tooling at the tip of the insert, are used to accurately record cutting temperatures in the immediate vicinity of the tool-chip interface with unprecedented temporal- and spatial-resolution. It has been shown that the embedded micro TFTC array can provide temperature measurements with a degree of resolution and dynamic content that is not possible with currently employed methods. The measurement results indicate that the cutting temperature variations and temperature-field distributions at and near the cutting zone are strongly influenced by the relationship between the heat generation and dissipation rates and the mechanics of chip formation.
