In this paper, the problem of constructing geometric models from data provided by 3-D imaging sensors is addressed. Such techniques allow for rapid model-ing of sculptured free-form shapes and generation of geometric models for existing parts. In order for a complete data set to be obtained, multiple images, each from a diierent viewpoint, have to be merged. A technique stemming from the Iterat...

the conventional tunneling procedures for example drilling, charging, blasting, loading and supporting, are highly developed. new tunneling machines have recently come into operation and others are under construction or development. impactors are used in large numbers in the coal mining industry. face-heading machines are successfully used in new tunneling procedures in both soft and medium-har...

Abstract The increasing demands of highly precise industrial products lead to continuous seeking for the improvements in cabapility manufacturing machines, i.e., machine tools. Machine tools include different types turning, lathe, drilling, and milling machines whatever computerized numerical control (CNC) type or manual type. cabaplity improvement requires a real understanding their productivi...

This article describes the structure and the working principle of the blind hole drilling device, by application in the production practice proves its feasibility. At present, we commonly used electrical discharge machining and welding method to solve the problem. However, these methods have the low processing efficiency, low manufacturing precision and high cost defect. This paper developed an...

The article is centred on software system development for manufacturing company that produces polyethylene bags using mostly conventional machines in a competitive world where each business enterprise desires to stand tall. This is meant to assist in gaining market shares, taking maintenance and production decisions by the dynamism and flexibilities embedded in the package as customers’ demand ...
