"Research in the field of Tool path generation for freeform surfaces has been done intensively in the past. However, the main challenge that still exists is the computational efficiency related to the tool path generation. Tool path generation for freeform surface involves instantaneous calculation of new tool orientations which does not collide with the neighboring surfaces. Since the collision check of tool and neighboring surface is done repetitively at every instant of the tool, the calculations at every instant are to be computationally as easy as possible. This thesis is composed of one paper. Paper I presents a novel extension of the Bounding Box technique used for collision detection. This novel method solves the above mentioned challenge of computational efficiency in the field of tool path generation. The new approach that has been implemented in Paper I involves using the simplest computational operators that are comparison operators along with a novel Diagonal Bounding Box technique. This ensures the tool path generation to be less cumbersome computationally. Furthermore, the boundaries of the proposed machining algorithm in terms of collision correction and the proper application of the machining algorithm have been explored"--Abstract, leaf iv.

(Cont.) * A scheme for computing a valid collision free orientation by performing a local search in the neighborhood of the "promising" visible direction using rapid collision avoidance algorithms. Visibility is a necessary but not a sufficient condition for accessibility because visibility cannot account for the geometry of the tool. * A scheme for determining a smooth interpolation between valid tool postures at the end points. This is not a trivial task because the tool must not interfere with the part while interpolating between valid postures. The visibility cones of the end points are used to compute a "globally" valid interpolatory path and the interpolated postures are then "locally" profiled for access by using rapid collision detection algorithms. The algorithms outlined in this thesis make it possible, for the first time, to generate 5-axis CNC tool paths automatically from a CAD file. The algorithms have been implemented and tested on several parts.

This book is written to help you learn the core concepts and steps used to conduct virtual machining using CAMWorks. CAMWorks is a virtual machining tool designed to increase your productivity and efficiency by simulating machining operations on a computer before creating a physical product. CAMWorks is embedded in SOLIDWORKS as a fully integrated module. CAMWorks provides excellent capabilities for machining simulations in a virtual environment. Capabilities in CAMWorks allow you to select CNC machines and tools, extract or create machinable features, define machining operations, and simulate and visualize machining toolpaths. In addition, the machining time estimated in CAMWorks provides an important piece of information for estimating product manufacturing cost without physically manufacturing the product. The book covers the basic concepts and frequently used commands and options you'll need to know to advance from a novice to an intermediate level CAMWorks user. Basic concept and commands introduced include extracting machinable features (such as 2.5 axis features), selecting machine and tools, defining machining parameters (such as feedrate), generating and simulating toolpaths, and post processing CL data to output G-codes for support of CNC machining. The concept 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 (cutter location) data verification by reviewing the G-codes generated from the toolpaths. This helps you understand how the G-codes are generated by using the respective post processors, which is an important step and an ultimate way to confirm that the toolpaths and G-codes generated are accurate and useful. This book is intentionally kept simple. It primarily serves the purpose of helping you become familiar with CAMWorks in conducting virtual machining for practical applications. This is not a reference manual of CAMWorks. You may not find everything you need in this book for learning CAMWorks. But this book provides you with basic concepts and steps in using the software, as well as discussions on the G-codes generated. After going over this book, you will develop a clear understanding in using CAMWorks for virtual machining simulations, and should be able to apply the knowledge and skills acquired to carry out machining assignments and bring machining consideration into product design in general.

The use of complex or sculptured surfaces to define object boundaries is universally acclaimed in today's industry. Specific applications, design requirements, industrial arts and aesthetics are some of industry's requirements that necessitate the use of sculptured surfaces in the representation of a product. Till recently industry relied mostly on 3-axis milling machines using a variety of milling cutters to machine sculptured surfaces. The need for reducing machining time, production cost and improving machining quality led to the development of 5-axis milling machines. This research proposes the use of toroidal or filleted end mills to overcome the problem of limited range of curvatures available on a tool, while making use of surface characteristics to achieve optimum cutter contact. The tool path generation technique followed in this research is a non-constant parameter offset tool path as opposed to constant parameter offset tool path. This ensures that the surface is not over machined thereby reducing machining time.

Planning of optimal toolpath, cutter orientation, and feed rate for 5-axis Computer Numerical Control (CNC) machining of curved surfaces using a flat-end mill is a challenging task, although the approach has a great potential for much improved machining efficiency and surface quality of the finished part. This research combines and introduces several key enabling techniques for curved surface machining using 5-axis milling and a flat end cutter to achieve maximum machining efficiency and best surface quality, and to overcome some of the key drawbacks of 5-axis milling machine and flat end cutter use. First, this work proposes an optimal toolpath generation method by machining the curved surface patch-by-patch, considering surface normal variations using a fuzzy clustering technique. This method allows faster CNC machining with reduced slow angular motion of tool rotational axes and reduces sharp cutter orientation changes. The optimal number of surface patches or surface point clusters is determined by minimizing the two rotation motions and simplifying the toolpaths. Secondly, an optimal tool orientation generation method based on the combination of the surface normal method for convex curved surfaces and Euler-Meusnier Sphere (EMS) method for concave curved surfaces without surface gouge in machining has been introduced to achieve the maximum machining efficiency and surface quality.

Computer-Aided Design and Manufacturing (CAD/CAM) is concerned with all aspects of the process of designing, prototyping, manufacturing, inspecting, and maintaining complex geometric objects under computer control. As such, there is a natural synergy between this field and Computational Geometry (CG), which involves the design, analysis, implementation, and testing of efficient algorithms and data representation techniques for geometric entities such as points, polygons, polyhedra, curves, and surfaces. The DIMACS Center (Piscataway, NJ) sponsored a workshop to further promote the interaction between these two fields. Attendees from academia, research laboratories, and industry took part in the invited talks, contributed presentations, and informal discussions. This volume is an outgrowth of that meeting.
