چکیده
A regional optimization of automatically generated machining toolpath for computer based freeform mechanical models is considered in the framework of multi-axis (three to ve) machining operations. Consider a trichotomy of an arbitrary freeform shaped surface into convex, concave and saddle-like regions. Saddle-like and concave regions can be milled using a ball end tool, in a 3or a 5-axis mode. A subset of the convex regions can be machined faster and with a smaller scallop, using a at end tool that is aligned with the normal of the surface, in 5-axis mode. A method to robustly detect and eliminate local gouging of the milling tool into the object is developed and demonstrated on an actual part.

Since the sub-axis of machine tool spindles subjected to fatigue loading, the effects of different surface heat treatments on fatigue behavior of 16MnCr5 steel have been investigated in the current work. After the test specimens were prepared from the steel, the surface heat treatments; carburizing, carbonitriding and a practical type of treatment involving the first nitriding then carburizing ...
متن کاملConstructing Variable Fidelity Response Surface Approximations in the Usable Feasible Region
The use of Response Surface Approximation (RSA) within an approximate optimization framework for the design of complex systems has increased as designers are challenged to develop better designs in reduced times. Traditionally, statistical sampling techniques (i. e., experimental design) have been used for constructing RSA’s. These statistical sampling techniques are designed to be space fillin...

متن کاملConvergence of trust region augmented Lagrangian methods using variable
To date the primary focus of most constrained approximate optimization strategies is that application of the method should lead to improved designs. Few researchers have focused on the development of constrained approximate optimization strategies that are assured of converging to a Karush-Kuhn-Tucker (KKT) point for the problem. Recent work by the authors based on a trust region model manageme...
