Abstract:

A software package and associated hardware have been developed which gives users of the ORAC CNC Training Lathe an easier and faster method of manufacturing on the lathe. The package, entitled ORACAP, uses the computing power of a mini-mainframe computer, a VAX 11/750, to assist in part design, program generation, program optimization, and program proving for the ORAC Lathe. The package is designed for users unfamiliar with computers such as students in an educational institute or workers in a production facility and uses command procedures to simplify the preparation and execution of the modu

Abstract:

The intent of the thesis is to automate the generation of computer numerical control (CNC) codes from geometrical computer-aided design (CAD) models. The work is carried out using two machines, the MDX 40A milling machine, and the HAAS VM3 machine. The case study is to determine the potential in automating the code generation process. The empirical findings from the research studies reveal that the manual process for programming the codes for the models pose a challenge of consuming more time using the procedures in computer-aided manufacturing and manual operations performed by a programmer.

There is no tool with a vanished radius that is matched to the path of tool. Practically, the simulation path in NC lathes is based on a tool without nose radius; however, the dimension of the nose radius is existed in the manufacturing process. For illustration, the compensation of the error is needed when an arc of a circle or an arc of a taper is encounter. The value of the compensation is ne

Abstract:

A pair of hypoid gears refers to a pinion and a gear with skew axes. Hypoid gears are crucial to some power transmission systems, such as those of helicopters, power generation machines and automobiles. However, the design and manufacturing of hypoid gears are quite difficult. Currently, the major parameters of hypoid gears are calculated, but the geometries of the gears are not fully defined. To machine a hypoid gear, parameters of cutting systems are determined according to the gear design, whereas, settings of CNC machine tools with the machining parameters are also computed.

Abstract:

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. Howe

This report has as main objective the development and application of a 3D printing module (additive manufacturing) in a computer numeric control (CNC) milling machine (subtractive manufacturing) creating a hybrid manufacturing environment that could offer the advantages of both methods. Every CNC milling machine using this 3D printing module could be converted in a 3D printer by changing from a regular tool to the 3D printing module which is applied in the spindle of the machine in a very simple process. This module is equipped with a system capable of reading the spindle rotation speed, and u

Therefore, the gear tooth deviation should be measured and then the flank correction is implemented based on the gear tooth deviation to improve the precision of gear. In domestic gear industry, most gears are off-machine measurement after manufacturing, but the errors and the time-consuming between loading and unloading will reduce the precision o

The Constraint Nets model (CN) proves to be useful for a wide variety of purposes, ranging from intelligent agent systems, and real-time embedded systems, to integrated hybrid systems with various time structures: discrete, continuous, and time-based. This thesis describes a new visual programming environment called CNJ (Constraint Nets in Java) which utilizes component-based technology. CNJ uses JavaBeans, Bean Introspection, drag-and-drop, and Java Swing MDI (Multiple Document Interface) technologies, as well as XML-based CNML as its standard interchange format.

The high-level parallel programming language CCC is a simple extension of C. CCC has three salient features for providing a virtual computing environment to support data parallel programming: virtual processors, synchronous execution, and global name space. In principle, CCC can provide better productivity than low-level communication libraries such as MPI and PVM, and can produce more efficient code

Abstract:

The concern of increasing energy consumption with depleting energy resources is ever growing. Though the solution to this problem lies in part in renewable energies, it is becoming increasingly clear that sustainable building design also plays a critical role. Controlling solar gain, for example, can greatly reduce the cooling energy consumption and lowering the peak cooling load. Having the ability to model these effects can have a substantial impact on the sizing of equipment and further reduce operational costs of a building. As a result, renewed interest has been invested by researchers an
