TRANSFER AND UNIT MACHINE While the specific intention and application for transfer and unit machine vary from one machine type to another, all forms of transfer and unit machine have common benefits. Here are but a few of the more important benefits offered by TRANSFER AND UNIT MACHINE equipment. The first benefit offered by all forms of transfer and unit machine is improved automation. The operator intervention related to producing workpieces can be reduced or eliminated. Many transfer and unit machine can run unattended during their entire machining cycle, freeing the operator to do other tasks. This gives the transfer and unit machine user several side benefits including reduced operator fatigue, fewer mistakes caused by human error, and consistent and predictable machining time for each workpiece. Since the machine will be running under program control, the skill level required of the transfer and unit machine operator (related to basic machining practice) is also redu

Structural and Multidisciplinary Optimization manuscript (authorsrsquo; post-print) Automated Optimal Design of a Two-Stage Helical Gear Reducer Tudose, L. · Buiga, O. · Scedil;tefanache, C. · Sacute;obester, A. Received: date / Accepted: date Abstract The design space of multi-stage transmis- sions is usually very large and heavily constrained. This places significant demands on the algorithm employed to search it, but successful optimization has the poten- tial to yield considerably better designs than conven- tional heuristics, at the same time enabling a better understanding of the trade-offs between various objec- tives (such as service life and overall weight). Here we tackle a two-stage helical gear transmission design prob- lem (complete with the sizing and selection of shafts, bearings, housing, etc.) using a two-phase evolutionary algorithm in a formulation that can be extended to in- clude additional stages or different layouts.
