In this paper, a simulated annealing algorithm has been developed to optimize machining parameters in turning operation on cylindrical workpieces. The turning operation usually includes several passes of rough machining and a final pass of finishing. Seven different constraints are considered in a non-linear model where the goal is to achieve minimum total cost. The weighted total cost consists...

The reliability of machining accuracy is of great significance to performance evaluation and optimization design of the machine tools. Different geometric errors have various influences on the machining accuracy of the machine tools. The main emphasis of this paper is to propose a generalized method to distribute geometric accuracy of component for improving machining accuracy reliability under...

Abstract Due to the great technological growth, 3D printing is becoming of relevance within automotive, aerospace and even medicine sectors. With this manufacturing method, parts with a complex geometry can be manufacture considerable time material savings compared traditional processes such as machining. However, additive still have series unresolved problems. Present work makes comparison bet...

Abstract Needled quartz fiber reinforced phenolic aerogel composite (NQF/PA) is a kind of lightweight thermal protection material commonly used in the aerospace field. With continuous development science and technology, design various spacecraft becoming more complex. Due to limitation preparation process, components are difficult be directly prepared formed. It often necessary carry out second...

Optimization of machining parameters is a vital task for increasing machining efficiency and economics. Selection of optimal machining parameters is often performed by integrating empirical models with traditional mathematical and meta-heuristic algorithms. Ability to deal with complex and multi-dimensional optimization problems resulted in growing interest on the application of meta-heuristic ...
