This article deals with aspects of accuracy of machine tools and quality of products. As there is a big influence of accuracy of individual components of machine tools on quality of product, it is very important to know all aspects and influences of technological system on final precision of product. Several aspects of diagnostics of machine tools are described, such as aspects of reliability.

some physical attributes of two common types of iranian garlic cloves (white and pink) were identified and compared. a machine vision system was used to determine three di-mensions and both major and minor projected areas of garlic cloves at a moisture content of 42.4% w. b. the geometric mean diameter and sphericity were calculated, as well as the unit mass and volume of cloves were measured. ...

In the near future, the foreseen improvement in machine tools will be in the form of a knowledge evolution-based intelligent device. The goal of this study is to develop intelligent machine tools having knowledge-evolution capability in Machine to Machine (M2M) wired and wireless environment. The knowledge evolution-based intelligent machine tools are expected to be capable of gathering knowled...

This paper presents an approach to Cartesian controlled heavy machines. The system under investigation is a drill rig equipped with two drilling booms each actuated by eight hydraulic drives. To improve accuracy and efficiency in both possible operation modes, drilling and bolting, a Cartesian control system has been implemented, which takes advantage of using different subsets of the redundant...

This paper presents the effects of various parameters of fabricated electro chemical micro machining (ECMM) setup on machining response characteristics during micro drilling of Hybrid Al/(Al2O3p+SiCp+Cp)-MMC. AnECMM setup has beendesigned and fabricatedfor the purpose. Fabricated ECMM setup has different units such as mechanical machine unit, electrical power supply and control unit, electrolyt...

Machine tools lie at the heart of almost all manufacturing systems, and their performance has a massive influence on both the performance and productivity of systems. In accordance with the development of computer systems, intelligent technologies have been applied to manufacturing systems, thereby raising the need for more intelligent machine tools. Intelligent machines respond to external env...

We present a data-driven and physics-informed algorithm for drilling accident forecasting. The core machine-learning uses the data from telemetry representing time-series. have developed Bag-of-features representation of time series that enables to predict probabilities six types accidents in real-time. model is trained on 125 past 100 different Russian oil gas wells. Validation shows can forec...
