Book Synopsis Optimization with Ruled Surface by : Yayun Zhou
Download or read book Optimization with Ruled Surface written by Yayun Zhou and published by Logos Verlag Berlin GmbH. This book was released on 2010 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation provides a novel design approach with respect to ruled surface, which is a special type of surface generated by moving a line in the space. Ruled surface is a favorable choice in manufacture and can be found in many application fields. In this dissertation, a ruled surface in Euclidean space is represented as a curve on a dual unit sphere (DUS) by employing the Klein mapping and the Study mapping. A novel definition of dual spherical spline is proposed and a complete kinematic ruled surface approximation algorithm is developed and tested with turbocharger blade data. More generally, a ruled surface is defined by several control points of a dual spherical spline. It provides an initial prototype for the blade geometry optimization with ruled surface. Finally, combining the kinematic ruled surface approximation algorithm with the offset theory, a novel design and manu- facturing strategy is proposed. A desired surface is presented as a tool path of the flank milling method with a cylindrical tool in 5-axis CNC machining. It integrates the manufacturing requirements in the design phase, which can reduce the design- cycle time and save the manufacturing cost.

Book Synopsis Geometry of Surfaces by : Stephen P. Radzevich
Download or read book Geometry of Surfaces written by Stephen P. Radzevich and published by Springer. This book was released on 2019-08-14 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: This updated and expanded edition presents a highly accurate specification for part surface machining. Precise specification reduces the cost of this widely used industrial operation as accurately specified and machined part surfaces do not need to undergo costly final finishing. Dr. Radzevich describes techniques in this volume based primarily on classical differential geometry of surfaces. He then transitions from differential geometry of surfaces to engineering geometry of surfaces, and examines how part surfaces are either machined themselves, or are produced by tools with surfaces that are precisely machined. The book goes on to explain specific methods, such as derivation of planar characteristic curves based on Plücker conoid constructed at a point of the part surface, and that analytical description of part surface is vital for surfaces machined using CNC technology, and especially so for multi-axes NC machines. Providing readers with a powerful tool for analytical description of part surfaces machined on conventional machine tools and numerically controlled machines, this book maximizes understanding on optimal treatment of part surfaces to meet the requirements of today’s high tech industry.
Book Synopsis The Optimization of Machining Parameters for Milling Operations by Using the Nelder Mead Simplex Method by :
Download or read book The Optimization of Machining Parameters for Milling Operations by Using the Nelder Mead Simplex Method written by and published by . This book was released on 2019 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: Machining operations need to be optimized to maximize profit for computer numerical control (CNC) machines. Although minimum production time could mean high productivity, it can not guarantee maximum profit rate in CNC milling operations. The possible range of machining parameters is limited by several constraints, such as maximum machine power, surface finish requirements, and maximum cutting force for the stability of milling operations. Among CNC machining parameters, cutting speed and feed have the greatest effect on machining operations. Therefore, cutting speed and feed are considered as main process variables to maximize the profit rate of CNC milling operations. A variety of numerical methods are used to optimize the machining process, such as the genetic algorithm, tabu search method, and ant colony algorithm. In CNC milling operations, an objective function proposed by Tolouei and Bidhendi was used to estimate the profit rate. Tolouei and Bidhendi used the method of feasible direction to maximize the profit rate of CNC milling processes. In this research, the Nelder-Mead simplex method will be tried to maximize the profit rate of CNC milling processes. The Nelder-Mead simplex method was selected to find an optimum value because it can be used when the derivative of a function is unpredictable due to nonlinearity. As such, this method is suitable for problems of statistical estimation.

Book Synopsis Advanced Virtual Simulation for Optimal Cutting Parameters Control in Five Axis Milling by : Hendriko
Download or read book Advanced Virtual Simulation for Optimal Cutting Parameters Control in Five Axis Milling written by Hendriko and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study presents a simple method to define the Cutter Workpiece Engagement (CWE) during sculptured surface machining in five-axis milling. The instantaneous CWE was defined by determining two engagement points, lowermost engagement (LE)-point and uppermost engagement (UE)-point. LE-point was calculated using a method called grazing method. Meanwhile the UE-point was calculated using a combination of discretization and analytical method. During rough milling and semi-finish milling, the workpiece surface was represented by vertical vector. The method called Toroidal-boundary was employed to obtain the UE-point when it was located on cutting tool at toroidal side. On the other hand, the method called Cylindrical-boundary was used to calculate the UE-point for flat-end cutter and cylindrical side of toroidal cutter. For a free-form workpiece surface, a hybrid method, which is a combination of analytical method and discrete method, was used. All the CWE models proposed in this study were verified and the results proved that the proposed method were accurate. The efficiency of the proposed model in generating CWE was also compared with Z-mapping method. The result confirmed that the proposed model was more efficient in term of computational time. The CWE model was also applied for supporting the method to predict cutting forces. The test results showed that the predicted cutting force has a good agreement with the cutting force generated from the experimental work.

Book Synopsis A Practical and Optimal Approach to CNC Programming for Five-Axis Grinding of the End-Mill Flutes by : Mahmoud Mohammad Rababah
Download or read book A Practical and Optimal Approach to CNC Programming for Five-Axis Grinding of the End-Mill Flutes written by Mahmoud Mohammad Rababah and published by . This book was released on 2011 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: For a solid carbide tapered end-mill, every flute includes a flute surface and a rake face along a helical side cutting edge, and the end-mill core is at the center and is tangent to all the flutes. The flutes significantly affect the tools cutting performance and life, and the core radius mainly affects the tools rigidity. Mainly, two methods are adopted in industry to grind the flutes; these are: the direct method and the inverse method. In the direct method, a flute is ground using a standard grinding-wheel moving in multi-axis machining to generate the rake face and the flute surface. However, the flute is the natural outcome of the grinding process without any control. On the other side, the inverse method employs the concept of inverse engineering to build a grinding-wheel that accurately grinds the end-mill flutes. This yields a free-form grinding-wheel profile that is used on a 2-axis grinding machine; however, the flute shapes are only exact on one section of the end-mill; when the grinding-wheel moves along the side cutting edge to smaller sections; the deviation of the generated flute from the designed one will be increased. Thus, neither can this method grind the rake face with the prescribed normal rake angle, nor generate the side cutting edge in good agreement with its design. Moreover, the grinding-wheel profile is very difficult and expensive to make. To address these problems, a practical and optimal approach for five-axis grinding of prescribed end-mill flutes is proposed by; first, establishing a 5-axis flute grinding theory describing the wheels locations and orientations during grinding the rake faces with constant normal rake angles; Second, introducing a simple grinding-wheel consisting of lines and circular arcs; and finally, applying an optimization algorithm to optimize the grinding-wheel shape and path. Overall, this approach significantly advances the CNC programming technique for the 5-axis flute grinding, and can substantially increase the quality of the solid carbide end-mills and lays a good foundation for the CAD/CAE/CAM of end-mills. The advantages of this approach over the other approaches are verified using computer simulation.
