Abstract
In this work, different non-contact fiber-optic pyrometers have been developed for measuring localized temperatures on material removal area during mechanizing processes. Designs are developed for adaptation to the harsh measuring conditions on specific cutting tool machinery and using commercial optoelectronics and fiber-optic components for resolution enhancement. A 0.1 dB/°C sensitivity at 300 °C is obtained, and calibration curves at 1100 nm, 1300 nm, 1550 nm and 1610 nm are reported. Different reception circuits are used for testing resolution limits, higher bandwidths imply greater noise and worst results as expected.
