High Pressure Coolant

This paper presents a finite-element modeling (FEM) of tool temperature distribution during high pressure coolant assisted turning of Inconel 718, which belongs to the heat resistance superalloys of the Nickel-Chromium family. Machining trials were conducted under four machining conditions: dry, conventional wet machining, high pressure coolant at 50 bar, and high pressure coolant at 80 bar. Temperature during machining plays a very important role in the overall performance of machining processes. Since in the current investigation a high pressure coolant jet was supplied in the cutting zone between tool and work material, it was a very difficult task to measure the tool temperature correctly. Thus, FEM was used as a modeling tool to predict tool temperature. The results of the modeling showed that the temperature was considerably influenced by coolant pressure: the high pressure jet was able to penetrate into the interface between tool and work material, thus providing both an efficient cooling and effective lubricating action.

Abstract In this paper a model is developed to analyze heat transfer and temperature distribution resulting during machining with rotary tools. The presented model is based on a finite-volume discretization approach applied to a general conservation of energy statement for the rotary tool and chip during machining. The tool rotational speed is modeled and its effect on the heat partitioning between the tool and the chip is investigated. The model is also used to examine the influence of tool speed on the radial temperature distribution on the tool rake face. A comparison between the predicted and previously measured temperature data shows good agreement. In general the results show that the tool-chip partitioning is influenced dramatically by increasing the tool rotational speed at low to moderate levels of tool speed. Also, there is an optimum tool rotational speed at which further increase in the tool rotational speed increases the average tool temperature.

Tool Temperature

Ti-6AL-4V is widely used in the industry for the high strength-to-weight ratio at elevated temperature, its excellent resistance to fracture and corrosion, and biological properties. However, Ti-6AL-4V is hard to manufacture for its reactive chemical properties and low thermal conductivity that causes high temperature on the tool surface. Prediction of the tool temperature distribution from different manufacturing ways, up and down milling, has great significance in predicting tool wear pattern (cutting speed, feed/tooth, and axial depth of cut) in corner milling on temperature of the tool rake face. The tool material used is general carbide and Johnson-Cook plastic model is utilized to model the behavior of the workpiece Ti-6AL-4V. A separate Abaqus heat transfer model is used to analyze the heat transfer process after the tooth disengages the workpiece and before it engages the workpiece again to predict change of temperature distribution during this cooling process. The comparison of the up milling and down milling on the tool temperature is conducted.

Tool Surface

A method was developed to measure tool temperature distribution within the tool by means of fine powders that have a constant melting point. The method involves observation of the boundary line formed by melted and unmelted powder scattered on the tool surface. It is clarified that temperature distribution within the tool is easily and accurately measured in this manner. Temperature distributions were compared with results obtained from analyses based on Loewen and Shaw’s theory, modified on the assumption that heat distribution due to friction along the rake face is not uniform but, rather, like real frictional distribution in cutting, and the fraction of heat flowing into the tool varies along the rake face.

Plate Size

In laser forming, deformation of a plate is different when different mechanisms play dominant roles. A deformation field depends on a temperature field that is related to process parameters, material properties and plate size. Numerical investigations of temperature distribution with different process parameters were carried out when different mechanisms were active. A critical temperature for generating plastic deformation was investigated. Four temperature feature parameters were defined based on the temperature distribution characteristics of the high-temperature zone. The numerical results show that the temperature gradient is obviously different under different mechanism conditions. The temperature distribution features for the different mechanisms have a larger difference, which is helpful for the discrimination of different mechanisms according to the temperature field in real industrial applications.
