I have a batch of solid baja (steel) blanks that must be turned on a konvensional (manual) lathe and brought to very tight tolerances for a precision-fit assembly. Because this is a pekerjaan presisi assignment, the dimensional accuracy needs to stay within ±0,02 mm on the critical diameters and face lengths, with surface finish no rougher than Ra 1,6 µm. You will be working entirely in steel, so please be comfortable selecting the correct cutting speed, tool geometry, and coolant to avoid work-hardening or chatter. Carbide inserts are fine as long as the finish requirement is met; HSS is acceptable if you prefer hand-honing your edge. The parts are simple shafts (max Ø50 mm, length 120 mm) but each includes a small relief groove and a 45° face chamfer that must b...

I want to decide on the most appropriate semiconductor switch for a new switch-mode power supply design, with switching speed as the overriding priority. Although I initially considered a thyristor, I’m open to any device—MOSFET, IGBT, BJT or another alternative—that demonstrably outperforms the rest once the figures are on the table. Here’s what the work entails. First, analyse the SMPS topology and its expected operating conditions, then shortlist realistic candidates and justify the final choice in terms of rise/fall times, turn-on/turn-off losses, and any ancillary gate-drive or snubber requirements. Once the device is chosen, run a full simulation (LTspice, PSpice, SIMetrix, MATLAB Simulink or equivalent) that shows switching waveforms, efficiency trends over ...

I need a COMSOL Multiphysics model of a high-frequency transformer that couples the electromagnetic and thermal physics so I can focus on thermal stress impacts. The goal is to see exactly where mechanical strain develops inside the core, windings, and insulation as temperatures rise during high-frequency operation. You’ll start from the transformer’s geometric and material data (I’ll supply those) and build a 3-D electro-thermal study that includes frequency-dependent copper and core losses, convection or forced-air boundaries, and, ideally, a transient run that tracks hot-spot evolution. Once the temperature field is solved, the model should translate that field into the corresponding thermal-induced stresses so I can compare stress levels against material limits. Bec...
