This article presents a description of a functional principle, a structural scheme and an operation of the technological photometrical equipment designed to determine the time of origin of thermal decomposition and development in polymer composite materials; this decomposition appears during machining of such materials in modes with high temperatures in the area of chip formation and represents one of the major defects of machined surfaces. The proposed equipment developed in Bauman MSTU allows to determine the value of thermal destruction during machining without harming product integrity. This equipment could be used for studying influence of machining conditions on the value of decomposition, for in-process detection and for adaptive control of machining in order to provide the required manufacturing quality.
