“…The influence of cutting parameters on cutting temperature was analyzed, and the prediction model was optimized by using genetic algorithm and RSM to obtain the optimal cutting parameters. Lima et al [20] utilized finite element software to simulate the tool-workpiece contact area under different cutting speeds, and obtained the distribution of milling temperature. Kus et al [21] adopted ANSYS software to simulate and analyze the cutting tool in the cutting process, and obtained the temperature distribution at the tool tip.…”

Titanium alloy is widely used in aerospace and other fields because of its high strength, low density, good corrosion resistance and high temperature resistance. In high speed milling titanium alloy, due to the poor thermal conductivity of titanium alloy and the change of cutting mechanism caused by high speed machining, it is great significance to study the cutting temperature in high speed milling process. Based on the moving heat source method, the temperature field model of milling workpiece considering spiral edge was established, and the influence of milling speed on workpiece temperature was analyzed through the change of heat flux during milling. The thermocouple wireless temperature acquisition system was used to record the change of workpiece surface temperature in the milling process, and MATLAB was used for the simulation analysis of milling temperature. The results showed that the cutting speed mainly affected the heat flux of the heat source, thereby caused temperature rise of the workpiece. The peak temperature and response speed of measuring point are different in varying spindle speeds and measuring point positions.

“…Pareto analysis is a statistical tool used to help determine the causes that make up a problem and their level of significance. 22 Pareto analysis can also be used in machining operations [23][24][25][26][27][28] and sheet metal forming operations [29][30][31] to determine parameters efficiency. In order to determine the efficiency of the parameters as a percentage (%), all standardized effects of the parameters were summed and divided by the standardized effect of the desired parameter.…”

“…22 However, Pareto analysis can also be used outside of the quality improvement method. In addition to determining the effectiveness of the parameters in machining operations such as turning 23 and milling, [24][25][26][27][28] it can also be used in the sheet metal forming operations such as ISF 29,30 and deep drawing. 31 Rauch et al 12 used to form the AA5083 alloy with three different forming strategies based on different toolpaths.…”

The Incremental Sheet Forming (ISF) is an effective forming method developed especially for rapid prototyping and small-batch production of sheet metals. The selection of parameters (in particular, vertical step size and toolpath geometry) in ISF is crucial. Besides, each parameter has different effects on the desired geometry, sheet thickness, forming time, and productivity. In this study, the ISF process was analyzed by investigating the effects of ISF parameters. For this purpose, AA5754 sheets were formed by different ISF parameters. The effects of toolpath strategies (based on the vertical step size) were examined with three spindle speeds and three feed rates. To achieve that objective, constant, increasing, and decreasing vertical step sizes were used for the first time in the same study. After the forming, the forming time, geometric tolerance, and thickness values were analyzed. Besides, the efficiency of each parameter on the ISF process was investigated with the Pareto analysis. It has been revealed that each strategy has some advantages and disadvantages in ISF. The shortest forming time (1.55 min), the best geometric tolerance values (−0.05 mm, +0.2 mm), and the best thickness values (0.58 mm, 0.51 mm) were achieved following toolpath strategy 1, strategy 2, and strategy 3, respectively. The Pareto analysis showed that spindle speed and feed rate have a significant effect on toolpath strategies. The results obtained from this study will shed light on the effective advancement of small-batch production of sheets. Furthermore, the study contributes to the determination of parameters according to which of the sheet metal properties are desired.

Temperature measurement in machining is complex, with many limitations and restrictions and these are linked to the measurement method and the process in which it will be applied. Tapping is one of the processes that imposes the most restrictions and limitations on temperature measurement methods. The chip-tool interface temperature is important data to feed numerical models and also to help in the analysis of wear problems and breakage of the cutting tap. The objective of this work is to quantify the temperatures found in tapping as a function of some process variables (cutting speed, workpiece material and cutting fluid), to understand how influential these variables are in temperature, since there are no results in the literature. for the threading process, and to show the advantages of adapting the tool-workpiece thermocouple method for the tapping process. The results show a 34% reduction in dry cutting temperature when compared to oil and emulsion conditions.
