Study of Cutting Temperature in Orthogonal Milling
Finite Element Method (FEM) based techniques are available to simulate metal cutting processes and offer several advantages including prediction of tool forces, distribution of stresses, and temperatures, estimation of tool wear, and residual stresses on machined surfaces, optimization of cutting tool geometry, and cutting conditions. However, work material flow stress and friction characterist...
متن کاملHigh Accuracy Multi-color Pyrometry for High Temperature Surfaces
An evaluation of previously proposed least-squares multi-color pyrometry methods was carried out to determine their highest achievable accuracy. The study was limited to the visible spectrum and the temperature range of 1700 to 3000 K, typical of electrode surfaces in high-power electric propulsion thrusters. A Monte-Carlo simulation of the various methods showed the effects that the number of ...
متن کاملTemperature measurements using multicolor pyrometry in thermal radiation heating environments.
Temperature measurements are important for thermal-structural experiments in the thermal radiation heating environments such as used for thermal-structural stress analyses. This paper describes the use of multicolor pyrometry for the measurements of diffuse surfaces in thermal radiation environments that eliminates the effects of background radiation reflections and unknown emissivities based o...
متن کاملThermal Measurement of harsh environments using indirect acoustic pyrometry
The inversion of a composite governing equation for the estimation of a boundary heat flux from ultrasonic pulse data is presented. The time of flight of the ultrasonic pulse is temperature dependent and can be used to predict the boundary heat flux. Sensitivities of the approach are examined, results from fabricated data are presented, and example solutions are provided with actual ultrasonic ...
متن کاملDirectly Visible Pairs and Illumination by Reflections in Orthogonal Polygons
We consider direct visibility in simple orthogonal polygons and derive tight lower and upper bounds on the number of strictly internal and external visibility edges. We also show a lower bound of ⌈n2 ⌉ − 1 on the number of diffuse reflections required for completely illuminating an orthogonal polygon from an arbitrary point inside it. Further, we derive lower bounds on the combinatorial complex...
