“…Efficiency is reduced when the machining conditions are non-standard, even if the suitable tool is selected. Theoretical studies should be carried out for each material to be machined and each type of cutting tools in order to provide high efficiency and to be able to make economical machining [1,2,[6][7][8][9][10]. It is specified that determination and application of cutting tool strategies and movements are critical in milling of volume casts, aeronautical and cutting casts [1][2][3][4][5].…”

In this study, surface roughness and cutting forces were investigated experimentally in milling of Al 7075 material by DLC coated end-mill cutting tools. Effect of tool path, feed and cutting depths on surface roughness and cutting forces was examined. Taguchi technique was used for optimization of the milling process. Also, a variance analysis (ANOVA) was used for determination of effect of each parameter on the obtained results.In conclusion, the relationship between the dependent and the independent variables was modelled with regression analysis. Optimal machinability of Al 7075 material by DLC coated end-mill was determined in this study.

In the face milling of large low-rigidity aluminium alloy parts, the heat generated is one of the most important issues and leads to thermal expansion of the workpiece and the serious reduction of dimensional and geometrical precision. In this paper, a new heat transfer analytical model for face milling was established based on the heat source method, in which the cutting edge of the machine tool was considered as a finite-length rotating line heat source. Then, a transient numerical simulation was also conducted to predict the temperature field on the machined surface in singletooth and multi-tooth milling by using the finite-element method (FEM). Finally, experiments involving the measurement of the aluminium alloy milling temperature were performed using a semi-artificial thermocouple, in which the hot end of the thermocouple was embedded into the machined surface to obtain the instantaneous face milling temperature. Those experimental results exhibited good agreement with the results from the theoretical analytical model and numerical simulation.

Tapping operations on hardened steels have always been a great challenge. Dry machining and two cooling systems were used when tapping hardened AISI H13 (53 HRC). Embedded thermocouples were used for temperature measurement close to the thread diameter in the radial and axial direction. A FEA model was used to evaluate the heat "Q", and coefficient of convection "h". The lowest temperature peak occurred with the flooded system, followed by the MQL, and dry condition. The heat and coefficient of convection increased when using the flooded system, followed by the MQL, compared to the dry condition. Those values were also in accordance with early published works, using different techniques.
