Design Selection of In-UVAT Using MATLAB Fuzzy Logic Toolbox

The design of tool holder was a crucial step to make sure the tool holder is enough to handle all forces on turning process. Because of the direct experimental approach is expensive, a few design of innovative ultrasonic vibration assisted tuning (In-UVAT) has proposed. This design has analyzed using finite element simulation to predict feasibility of tool holder displacement and effective stress. SS201 and AISI 1045 materials were used with sharp and ramp corners flexure hinges on design. To decide which one the design is selected was used MATLAB Fuzzy Logic Toolbox. The result shows that AISI 1045 material and which has ramp corner flexure hinge was the best choice to be produced. It has the Eff. Stress Static equal 3, Displacement Static equal 17.5, Eff. Stress Dynamic equal 3, Displacement Dynamic equal 17.5 and Durability Value is 86.4.

Design selection of an innovative tool holder for ultrasonic vibration assisted turning (IN-UVAT) using finite element analysis simulation

On of high technology in machining is ultrasonic vibration assisted turning. The design of tool holder was a crucial step to make sure the tool holder is enough to handle all forces on turning process. Because of the direct experimental approach is expensive, the paper studied to predict feasibility of tool holder displacement and effective stress was used the computational in finite element simulation. SS201 and AISI 1045 materials were used with sharp and ramp corners flexure hinges on design. The result shows that AISI 1045 material and which has ramp corner flexure hinge was the best choice to be produced. The displacement is around 11.3 micron and effective stress is 1.71e+008 N/m2 and also the factor of safety is 3.10.
