Abstract

The objective of this work is to fabricate instrumented cutting tools with embedded thermocouples to accurately measure the tool-chip interface temperature in interrupted and continuous turning. Thin-film thermocouples were sputtered directly onto the flat rake face of a commercially available tungsten carbide cutting insert using micro machined stencils and coated the measurement junction with a protective layer to obtain temperature data 1.3 µm below the tool-chip interface. Oblique interrupted cutting tests on AISI 12L14 steel were performed to observe the influence of varying cutting speeds and cooling intervals on tool chip interface temperature. An additional cutting experiment was conducted to monitor the interface temperature change between interrupted and continuous cuts.
