Titanium Alloy Ti6al4v

Drilling experiments of titanium alloy Ti6Al4V were conducted. Taking the speed and feed as the process variables, a set of experimental cutting forces are obtained and compared. From the experimental results it is concluded that within the experimental extent the thrust force and torque of drilling process rises with the feed rate. The lower spindle speed resulted in the greater amount of thrust. Feed rates have greater influence on the thrust force than the spindle speed. The combination of greater feed rate and lower spindle speed results in the maximum amount of thrust. However, combination of greater feed rate and spindle speed resulted in maximum amount of torque.

Titanium Alloy Ti6al4v

Titanium alloy Ti6Al4V has poor machinability, which leads to high unit cutting force and cutting temperature, rapid tool failure. In this study, the effect of the cutting speed, feed rate and cooling condition on cutting force and cutting temperature is critically analysed by turning experiment. At the same time, the relationship is established among tool wear, cutting force and cutting temperature. This investigation has shown that cutting speed is the decisive factor which increasing cutting force and cutting temperature. In the process of turning, tool wear results in high amounts of heat and mechanical stress, which leads to serious tool wear. The Minimal Quantity Lubrication reduces the frictional condition at the chip-tool, decreases cutting force and cutting temperature, and delays the tool failure.

It is necessary for cutting simulation to determine the friction model at the tool-chip interface suitable for metal cutting process. Cutting force experiments in orthogonal turning titanium alloy TI6AL4V are carried out with cement carbide tool KW10. The Coulomb frictions at the tool-chip interface are calculated based on measured cutting force, and the friction model is regressed, where cutting speed and feed rate are presented.

Milling tests were undertaken to analyze and compare the machinability of hydrogenated titanium alloy Ti6Al4V. Uncoated WC-Co tool inserts were used in the study. The feed and the depth of milling were maintained constant, and only the milling speed was varied because it is the most affecting parameter. Results showed that cutting force and tool life were greatly influenced by the contents of hydrogen. Tool life decreased at first and then increased gradually with the increase of hydrogen content, and the maximum magnitude decrease of tool life is about 0.2%H, meanwhile, the maximum tool life is about 0.5%H. However, with the increase of cutting speed, the favorable effect of hydrogen on the titanium alloy machinability would be weakened even disappear, therefore, 50-100m/min would be a suitable choice of cutting speed.

Cutting force coefficients were conventionally described as the power function of instantaneous uncut chip thickness. However, it was found that the changes in the three controllable machining parameters (cutting speed, feed and axial cutting depth) could significantly affect the values of cutting coefficients. An improved cutting force model was developed in this article based on the experimental investigation of end milling titanium alloy (Ti6Al4V) with polycrystalline diamond tools. The relationships between machining parameters and cutting force are established based on the introduction of the new cutting coefficients. By integrating the effects of varying cutting parameters in the prediction model, cutting forces and the fluctuation of cutting force in each milling cycle were calculated. Validation experiments show that the predicted peak values of cutting forces highly match the experimental results; the accuracy of the model is up to 90% in predicting instantaneous cutting forces.

Titanium Alloy Ti6al4v

The titanium alloy thin-walled structure has been widely used in aircraft construction as one of the main load-bearing components. However, it is difficult to ensure the machining accuracy because of the machining difficulties of materials and structures. This paper takes titanium alloy (Ti6Al4V) thin-walled web as the research object and analyzes the factors of milling deformation. Based on the analysis, the milling process of the titanium alloy thin-walled structure is optimized, including the decrease of cutting force and the increase of processing system rigidity. Furthermore, a reasonable milling scheme is put forward.
