The article proposes concept of solution development for diagnosis and control of real-time cutting tool in for edge cutting machining. The functional model of a diagnosis subsystem based on data reading from sensors of various types established in a cutting zone is developed. Algorithms of subsystem accepted signals processing and averaging, allowing define condition of cutting tool with defin...

Captain Basile is a robot inspired from the cockroach and built to participate at the SAE Walking Machine Challenge 2004, an undergraduate competition of walking robots. The robot weighs 35 kg and is 86 cm long, 58 cm wide and 38 cm tall. Initially validated by the use of dynamic simulations, this pneumatic actuated hexapod is characterised by specialized legs, passive visco-elastic elements an...

Machining is a manufacturing process that can be used to produce precision machine parts and has many advantages. The first the ability achieve superior surface quality. Tool wear an inevitable phenomenon occurs during machining. It affected by machining conditions; therefore, this needs monitored controlled. In study, tool roughness tests were carried out on AISI 4462 duplex stainless-steel ma...

New demands are being placed on monitoring systems in precision manufacturing because of recent developments and trends in machining technology and machine tool design. This paper first discusses the requirements for sensor technology for precision manufacturing process monitoring in general. Then, background and details are given about acoustic emission (AE) and the application of AE sensing t...

In this paper, we present the design, modeling and preliminary control of RHex, an autonomous dynamically stable hexapod possessing merely six actuated degrees of freedom (at the hip attachment of each leg). Our design emphasizes mechanical simplicity as well as power and computational autonomy, critical components for legged robotics applications. A compliant hexapod model, used to build a sim...

This paper describes the design and development of an interactive multimedia simulator for pre-operational setup procedures on a computer numerically controlled turning center. This is part of an effort to develop training tools to supplement the online education program offered at the University of Houston. The benefits of such a simulator is that it acts as a computer based training tool for ...

Optical components of non-planar geometry require special machining to produce. Single point diamond turning is the manufacturing method of choice to produce these surfaces. Three main factors contribute to the quality of these surfaces. Machine accuracy has shown improvements with the increased use of air bearings. Tool wear and design are shown to be effected by the crystal orientation of the...

The challenge of recent machining industries is reduce lead time and increase production rate in order to maintain their competitiveness. This paper investigates the machinability of mild steel in turning process perform on conventional lathe machine. Twoparameters like tool rake angle and feed are varied to investigate their effect on material removal rate. An attempt has been made to model th...

Internet content today is about 80% text-based. No matter static or dynamic, the information is encoded and presented as multilingual, unstructured natural language text pages. As the Semantic Web aims at turning Internet into a machine-understandable resource, it becomes important to consider the natural language content and to assess the feasibility and the innovation of the semantic-based ap...

The Open Mind Common Sense project has been collecting common-sense knowledge from volunteers on the Internet since 2000. This knowledge is represented in a machine-interpretable semantic network called ConceptNet. We present ConceptNet 3, which improves the acquisition of new knowledge in ConceptNet and facilitates turning edges of the network back into natural language. We show how its modula...
