of the tool probe and is forged by the intimate contact of the tool shoulder and the pin profile. As a result of this process, a joint is produced in "solid state" [13]. Fig. 1 Parts of FSW tool [12..., tool pin profile, tool rotational speed, welding speed and axial force. Tools made of high carbon high chromium steel (HCHCr) with different tool profiles, i.e., straight square, tapered square......
Effects of laser phase transformation hardening parameters on heat input and hardened-bead profile quality of unalloyed titanium D. S. BADKAR1, K. S. PANDEY1, G. BUVANASHEKARAN2 1... geometry (i.e. hardened bead width (HBW), hardened depth (HD) and angle of entry of hardened bead profile with the surface (AEHB)) were investigated using response surface methodology (RSM......
products through LCA tool are gotten in Table 2. Depending on the number of impact categories in LCIA profile, a three-layer BP network is set up as shown in Fig.5, which has a five-neuron input layer...ANN valuation model of material LCIA profile CHEN Wei-ping(陈维平), LIU Hua(刘 华), ZHAO Hai-dong(赵海东),ZHU Quan-li(朱权利), LI Yuan-yuan (李元元) (College of Mechanical Engineering, South China......
strength of FSSW samples in AA 5754 aluminum alloy with increasing TPD. The influence of tool pin profile on the lap shear strength of these FSSW samples under varying TPDs was also studied. The stir tools... by mechanical pin interlocking or by metallurgical bonding. The effect of tool plunge depth on the stir zone formation and the influence of frictional heat flux on the lower sheet were revealed through......

In addition, changes can be made to the existing vibrating system......
thread taper tool pin profile with a shoulder diameter of 12 mm and constant pin diameter of 4 mm (Fig. 1(c)). Trial runs were carried out for five distinct TAs, viz., 0°, 1°, 2°, 3°, and 4°, and other... J. Effect of geometry of tool pin profile on the mechanical and metallographic characteristics of friction stir welded AA5052-H32 aluminium alloy [J]. Journal of Manufacturing Technology Research......
can be simply applied to measuring the temperature of workpiece just beneath the tool. The effects of preheating temperature and pin angle on temperature distribution were also studied numerically...], RUSSELL and SHEERCLIFF [11] investigated the effect of tool shoulder material and pin tool on heat input during the FSW. Most currently, DONNE et al [12] reported the measured residual stresses......

:The rotational tool is put forward, which is composed of the one-spiral-flute shoul-der and the rotational pin with screw. Using the turbulent model... of the tool while the material near tool flows more violently than the other regions. For the tapered rotational pin, the flow velocity of material inside the workpiece decreases with the increase......
for face-hobbed straight bevel gear using a hypocycloidal mechanism. SIMON [10-12] investigated the influence of tooth modifications induced by machine tool setting and head-cutter profile variations... is fixed, no generating roll is employed, so the profile shape of tooth on a workpiece is produced directly from the profile shape on the tool. 2.1.1 Part (a) of generating surface for gear circular......
