Aim. In the study learning trial was made to make a mathematical model of assembling process in connections " tungsten carbide insert cutter - cone", while methods statistics were applied. This makes it possible determine parameters distribution closing link. Accordingly, tension is determined by samples constituent links. For this purpose, amount investigated. Tension affects change stress, wh...

This paper research of productivity and work organization were investigated of a group made of five workers (two cutters, two tractor drivers and one cutter-inspector) and a team leader. The teamwas equipped with two tractors and three chain saws. The research was carried out in the area of management unit – Ju`na Krndija Kutjeva~ka, at an altitude ranging between 550 m and 750 m in a 55-year b...

The motion of a stone skimming over a water surface is considered. A simplified description of the collisional process of the stone with water is proposed. The maximum number of bounces is estimated by considering both the slowing down of the stone and its angular stability. The conditions for a successful throw are discussed. © 2003 American Association of Physics Teachers. @DOI: 10.1119/1.151...

Bilateral asymmetry of the paired claws of the lobster Homarus americanus is determined during the fourth and fifth juvenile stages by differential reflex activity; the side with the greater activity becomes the crusher while the contralateral side becomes the cutter. Juvenile lobsters reared during this critical period with a substratum that could not be grasped or with reduced input from pred...

This paper presents a three-component fixed dynamometer based on a strain gauge, which reduces output errors produced by the cutting force imposed on different milling positions of the workpiece. A reformative structure of tri-layer cross beams is proposed, sensitive areas were selected, and corresponding measuring circuits were arranged to decrease the inaccuracy brought about by positional va...

This paper presents a complete procedure for tool path planning and blade machining in 5-axis manufacturing. The actual cutting contact and cutter locations can be determined by lead and tilt angles. The tool path generation is implemented by piecewise curved approximation and chordal deviation detection. An application about drive surface method promotes flexibility of tool control and stabili...
