INSTRUCTIONS The technology for ultra-precision machining has been developed rapidly and steadily. In recent years, the demand for free form, complex and microscopic cutting has increased as a result of the need for highvalue-added fabrication for items such as high NA glass lenses, micro-grooves, diffractive aspheric lenses and other optical components. The ultra-precision machine for cutting ...

This paper introduces the new FundemantalWave library which is included in the Modelica Standard Library 3.2. The presented Modelica package provides models and components of rotating electrical three phase machines. The presented electrical machine models are fully compatible with the original Machines library of the electrical domain but rely on the concept of the magnetic potential and magne...

Machine condition monitoring (MCM) enables real time health assessment, prognostics, and advisory generation by interpreting data from sensors installed on the machine being monitored. To effectively utilize measurements for determining the health of individual components, macro-components and the overall system, these measurements must somehow be combined or integrated to form a holistic pictu...

This paper deals with machine repair problem with balking and reneging. There is provision of mixed standby (warm and cold) components to replace the failed machines. The lifetime and repair time are assumed to have exponential distribution. Birth-death technique is suggested to obtain the queue size distribution in explicit form. A repair facility of C permanent repairmen is facilitated to rep...

Machine controllers built from standardized software components have the greatest potential to reap open architecture benefits – including plug-and-play, reusability and extensibility. A challenge to component-based controllers relates to standardizing behavior in a non-restrictive manner to accommodate component packaging and component integration. Control component packaging requires behavior...

that a shockload of 45 kW should be allowed. The desien of The development of a simple chopper harvester is described and ways in which this complicated machine might be simplified are suggested. The decisions taken and some of the specially designed components used in 'building the machine are described and the difficulties experienced during its operation and their solution are explained.

The research in this paper deals with the application of qualitative models and statistical methods in quality control of production procedures of various components of industrial press machines. The qualitative simulation of discrete-event machine systems is often based upon the use of qualitative simulation and discrete-event methods techniques too. In order to describe and analyze machine sy...
