Questions of construction of jet-drop optical measuring systems: registration of acoustic emission signals and temperature measurement in the cutting zone during turning, drilling and milling

Abstract

The article deals with the use of jet-drop optical measuring systems (JDOMS) on machine tools for recording acoustic
emission (AE) signals and pyrometric temperature measurement in the cutting zone. The work of JDOMS is considered on the examples of metal working with the supply to the cutting zone of cutting coolant directed by a jet or through the internal through-holes of the cutting tool. It is shown that the coolant flow is used for directional transmission from the cutting zone of AE signals to the hydrophone as a sound guide and light of the infrared range to the pyrometer as a light guide. In the first case, AE signals are recorded to control the metal working conditions in the cutting zone, and in the second case, its temperature is measured.
