This paper describes the principles of dynamic referencing for optical CMMs and demonstrates the advantages of this new functionality in terms of measurement accuracy in shop floor conditions. Recent optical triangulation–based CMMs are now able to simultaneously measure multiple 3D points. With the help of markers placed on the part being measured, it is now possible to continuously monitor an...

According to the growing trend of IT-based systems, implementation of computerized maintenance management system (CMMS) in Iran’s power industry can dramatically help in optimized management of maintenance activities, and thereby, reducing equipment failures, increasing reliability, increasing product stability and, above all, increasing efficiency and productivity of the employees of this indu...

In most of the industries, classical reliability-centered maintenance (RCM) is employed to decide the maintenance strategies using reliability data without having adequate interaction with the design and operational systems. This means that the RCM process will be conducted with no or limited access to the design and operational data/knowledge. Commonly, the developed maintenance strategies are...

The abstract should summarize the contents of the paper and should contain at least 70 and at most 150 words. It should be set in 9-point font size and should be inset 1.0 cm from the right and left margins. The coordinate measuring machine systems (CMMS) are widely used for part inspections in manufacturing plants, which mostly include bridge CMMS and horizontal CMMS driven by motor and portab...

Computerized maintenance management systems (CMMS) are required to manage and control asset, plant, and equipment maintenance in today’s hospitals. A CMMS is much more than just a way to schedule preventive maintenance (PM). By using a CMMS, you can create equipment logs to record events associated with a piece of equipment; create work orders automatically according to a schedule or manually f...

In this report, we describe the preparation and electrochemical characterization of a Pt electrocatalyst, which was synthesized from hexachloroplatinic acid, using the incipient wetness impregnation method. This carbon mesoporous materials (Pt-CMMs) electrocatalyst was used for catalyzing the oxidation of methanol and its oxygen-reduction reaction. The electrocatalytic oxidation of methanol was...

Composite metamaterials(CMMs) combining a subwavelength metallic hole array (i.e. one-layer fishnet structure) and an array of split-ring resonators(SRRs) on the same board are fabricated with gold films on silicon wafer. Transmission measurements of the CMMs in the terahertz range have been performed. Dualband magnetic resonances, namely, a LC resonance at 4.40 THz and an additional magnetic r...

Background. A priority in hand therapy following Dupuytren’s fasciectomy is to regain and maintain extension of the proximal interphalangeal joint (PIPJ). Historically this has been achieved through the application of mechanical stress to the affected digit with splinting and exercise. However, loss of a normal pattern of digital flexion in both the operated and non-operated digits is a common ...

Latest generation of Coordinate Measuring Machines are complex mechatronic products that have they own parameters of accuracy. CMMs are used for a wide range of precise measurement and inspection tasks including complex parts with curved lines and shapes. CMMs are used in metrology laboratories as well as on shop floor. They are often exposed to variety of microclimatic influences on accuracy (...
