Optimizing vacuum grippers of robots for glass sheets handling and developing robots for glass cleaning, it is necessary to solve a number of problems calling for a similar approach to a solution. This paper analyzes deformation behaviour of vacuum gripping elements of vacuum grippers. The extent of deformation safety of an individual suction cup is monitored depending on the vacuum level and loadi (…)
The present study is concerned with examining metallurgical features and their significance on strength and impact toughness of tin bronzes, with particular reference to bells. It has embraced a number of interrelated aspects – alloy types – composition, constitution and properties, fabrication technology, service life and effects of environmental/working conditions on strength and impact toughness (…)
Production (manufacturing) flexibility is one of the dominant requirements of the present engineering industry. Automated assembly systems have a special position because of their technical and technological complexity. At the present the problem of determination of existing or planned assembly systems flexibility is elaborating at the many research workplaces. The attention is focused on to elabor (…)
This paper describes basic principle of the state feedback control technique and its potential for the feed drive control in the machine tool domain. It evaluates the quality of the state control and compares it with the traditional cascade control. The emphasis is put on an estimation of the state variables using an FEM model of the feed drive mechanical structure and machine frame.
