The Assessment of Cutting Temperature Measurements in High-Speed Machining

Abstract

High-speed machining has received important interest because it leads to an increase of productivity and a better workpiece surface quality. However, the tool wear increases dramatically in high-speed machining (HSM) operations due to the high cutting temperature at the tool-workpiece interface and chip-tool interface. Cutting temperature and its gradient play an important role in tool life and machined part accuracy. This paper reviews different methods of the measurements of cutting temperature, which include: (1) thermocouples---tool-work thermocouple, embedded thermocouple, combination thermocouple and compensation thermocouple (2) optical infrared pyrometer, (3) infra-red photography, (4) thermal paints, (5) microstructure or microhardness observation. Each method has its advantages and limitations. The fundamental principles and application fields of each measurement method are presented, which is useful for the selection of the measurement methods for high-speed cutting temperature.

Analytical and numerical solutions of transient heat conduction in monolayer-coated tools

“…They also found that the analytical solutions by using relevant computer program were convenient and accurate. Wan et al (2004) summarized the present methods used to measure the cutting temperature, and analysed their merits and demerits and application ranges. Komanduri and Hou (2001c) also gave a review of the literature on several methods of temperature measurements.…”

Taguchi Analysis of the Deformation Characteristics of Single-Point Cutting Tool with Micro-Tool Coatings During Orthogonal Machining

“…Tool wear is mainly caused by excessive temperatures in the heat zones which can be overcome by a suitable coating on the cutting tool [17]. Carbide coatings are known to impart better hot hardness and higher resistance to diffusion mechanism till 1100 °C, preventing the phenomenon of chip-welding to the tool rake surface [18].…”

Determination of Rheological Properties of Titanium Alloys under Conditions of High Strain Rates

“…Various methods have been developed to solve the problem of thermal mapping of the cutting tool, workpiece and chips, for example: analytical methods [5] experimental and numerical (modeling) techniques [6], hybrid methods and techniques of the heat source. Several analytical models have been previously proposed by Merchant [7], which was developed by Oxley [8,9,10], latest works been adapted for the milling process [11].…”
