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.

Available in PDF, EPUB and Kindle. Book excerpt: The ultimate goal in the manufacturing of a part is to achieve an economic production plan with precision and accuracy in the first attempt at machining. A physics-based comprehensive modeling of the machining processes is a fundamental requirement in identifying optimal cutting conditions which result in high productivity rates without violating accuracy throughout the part production process. This thesis presents generalized virtual simulation and optimization strategies to predict and optimize performance of milling processes up to 3-axis. Computationally efficient mathematical models are introduced to predict milling process state variables such as chip load, force, torque, and cutting edge engagement at discrete cutter locations. Process states are expressed explicitly as a function of helical cutting edge - part engagement, cutting coefficient and feedrate. Cutters with arbitrary geometries are modeled parametrically, and the intersection of helical cutting edges with workpiece features are evaluated either analytically or numerically depending on geometric complexity. The dynamics of generalized milling operations are modeled and the stability of the process is predicted using both time and frequency domain based models. These algorithms enable rapid simulation of milling operations in a virtual environment as the part features vary. In an effort to reduce machining time, a constraint-based optimization scheme is proposed to maximize the material removal rate by optimally selecting the depth of cut, width of cut, spindle speed and feedrate. A variety of user defined constraints such as maximum tool deflection, torque/power demand, and chatter stability are taken into consideration. Two alternative optimization strategies are presented: pre-process optimization provides allowable depth and width of cut during part programming at the computer aided manufacturing stage using chatter constraint, whereas the post-process optimization tunes only feedrate and spindl.

This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Virtual manufacturing (VM) is a virtual reality based engineering application that provides an environment to model and simulate an actual manufacturing system through effective use of computers. Virtual computer numerical control (VCNC), which falls under the realm of virtual manufacturing applications, involves the development of a computer based virtual environment for modeling and simulating the functionality of a machine tool and the material removal process. In this thesis, virtual modeling and simulation of Bridgeport Series I CNC R2E3 Milling Machine with BOSS 81 (Bridgeport Operating System Software) controller and Cincinnati Milacron Sabre 750 3-axes CNC Vertical Machining Center with Acramatic 2100E CNC open architecture controller are presented. The above-mentioned virtual machine tools, which were developed using Deneb's Virtual NC version2.1 simulation software, provided the means for realization of the machining process on a computer, before the actual machining process is commenced on the real machine. Various CNC programs developed for machining various parts were simulated using the developed virtual CNC machines and virtual CNC controller. The virtual controller has the capability for detecting collisions between the different machine components as the CNC part program is being simulated. While running the simulation, the user can observe the changes in various parameters like feed rate, depth of cut, material removal rate, cycle time etc. Virtual machine tools that were developed will help in improving the quality of machined components, eliminating catastrophic program errors and optimizing the cutting path. As a future work, the developed virtual machine tools can be incorporated in a web-based virtual environment where the user can input his CNC programs through a graphical user interface for simulation"--Abstract, page iv

Download or read book Machining Simulation Using SOLIDWORKS CAM 2019 written by Kuang-Hua Chang and published by SDC Publications. This book was released on 2019-06 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will teach you all the important concepts and steps used to conduct machining simulations using SOLIDWORKS CAM. SOLIDWORKS CAM is a parametric, feature-based machining simulation software offered as an add-in to SOLIDWORKS. It integrates design and manufacturing in one application, connecting design and manufacturing teams through a common software tool that facilitates product design using 3D solid models. By carrying out machining simulation, the machining process can be defined and verified early in the product design stage. Some, if not all, of the less desirable design features of part manufacturing can be detected and addressed while the product design is still being finalized. In addition, machining-related problems can be detected and eliminated before mounting a stock on a CNC machine, and manufacturing cost can be estimated using the machining time estimated in the machining simulation. This book is intentionally kept simple. It’s written to help you become familiar with the practical applications of conducting machining simulations in SOLIDWORKS CAM. This book provides you with the basic concepts and steps needed to use the software, as well as a discussion of the G-codes generated. After completing this book, you should have a clear understanding of how to use SOLIDWORKS CAM for machining simulations and should be able to apply this knowledge to carry out machining assignments on your own product designs. In order to provide you with a more comprehensive understanding of machining simulations, the book discusses NC (numerical control) part programming and verification, as well as introduces applications that involve bringing the G-code post processed by SOLIDWORKS CAM to a HAAS CNC mill and lathe to physically cut parts. This book points out important, practical factors when transitioning from virtual to physical machining. Since the machining capabilities offered in the 2019 version of SOLIDWORKS CAM are somewhat limited, this book introduces third-party CAM modules that are seamlessly integrated into SOLIDWORKS, including CAMWorks, HSMWorks, and Mastercam for SOLIDWORKS. This book covers basic concepts, frequently used commands and options required for you to advance from a novice to an intermediate level SOLIDWORKS CAM user. Basic concepts and commands introduced include extracting machinable features (such as 2.5 axis features), selecting a machine and cutting tools, defining machining parameters (such as feedrate, spindle speed, depth of cut, and so on), generating and simulating toolpaths, and post processing CL data to output G-code for support of physical machining. The concepts and commands are introduced in a tutorial style presentation using simple but realistic examples. Both milling and turning operations are included. One of the unique features of this book is the incorporation of the CL data verification by reviewing the G-code generated from the toolpaths. This helps you understand how the G-code is generated by using the respective post processors, which is an important step and an excellent way to confirm that the toolpaths and G-code generated are accurate and useful. Who is this book for? This book should serve well for self-learners. A self-learner should have basic physics and mathematics background, preferably a bachelor or associate degree in science or engineering. We assume that you are familiar with basic manufacturing processes, especially milling and turning. And certainly, we expect that you are familiar with SOLIDWORKS part and assembly modes. A self-learner should be able to complete the fourteen lessons of this book in about fifty hours. This book also serves well for class instruction. Most likely, it will be used as a supplemental reference for courses like CNC Machining, Design and Manufacturing, Computer-Aided Manufacturing, or Computer-Integrated Manufacturing. This book should cover five to six weeks of class instruction, depending on the course arrangement and the technical background of the students.

Download or read book Advanced Design and Manufacturing Based on STEP written by Xun Xu and published by Springer Science & Business Media. This book was released on 2009-09-29 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Design and manufacturing is the essential element in any product development lifecycle. Industry vendors and users have been seeking a common language to be used for the entire product development lifecycle that can describe design, manufacturing and other data pertaining to the product. Many solutions were proposed, the most successful being the Stadndard for Exchange of Product model (STEP). STEP provides a mechanism that is capable of describing product data, independent from any particular system. The nature of this description makes it suitable not only for neutral file exchange, but also as a basis for implementing, sharing and archiving product databases. ISO 10303-AP203 is the first and perhaps the most successful AP developed to exchange design data between different CAD systems. Going from geometric data (as in AP203) to features (as in AP224) represents an important step towards having the right type of data in a STEP-based CAD/CAM system. Of particular significance is the publication of STEP-NC, as an extension of STEP to NC, utilising feature-based concepts for CNC machining purposes. The aim of this book is to provide a snapshot of the recent research outcomes and implementation cases in the field of design and manufacturing where STEP is used as the primary data representation protocol. The 20 chapters are contributed by authors from most of the top research teams in the world. These research teams are based in national research institutes, industries as well as universities.
