Infrared Thermography of the Chip-Tool Interface through Transparent Cutting Tools

Abstract
In-situ observation of the chip-tool interface has been carried out while machining Ti-6Al-4V. A low-noise camera sensitive to visible and near infrared (IR) radiation has been used to record the radiation emitted by the interface, and relatively long exposure times are used to obtain the time averaged temperature distribution. The image intensity is converted into temperature using a calibration equation. Emissivity values found in the literature are compensated for emission into YAG. The temperature along the rake face increases with distance from the cutting edge along the chip flow direction, reaching a maximum near the middle of the contact area. For a cutting speed of 1m/s, the time averaged temperature distribution shows a peak temperature of 906 C.Proceedings Title
