MILLING PROCESS MONITORING BY HIGH-SPEED IR THERMOGRAPHY

Abstract

The technological development of the most

recent years has considerably expanded the

possibilities for experimental analysis of cutting

processes: dynamometers and faster acquisition

systems, video and high-speed thermography ...

In this work the possibilities of the use of

high-speed IR thermography in rotating tool

processes such as milling are shown. Although

the lR thermography may present problems,

such as the complexity of the characterization

of the measurement chain and the uncertainty

estimation, its implementation is very useful.

Applications under conditions close to industrial

ones are shown for studying the temperature in

the workpiece or in the tool itself, both in absolute

terms (by knowing the temperature at each time)

and relative terms (by knowing the temperature

variation when the machining strategy or the

specific cutting conditions change).
