Abstract: A novel edge treatment method that utilizes a tip-burnishing process with an active rotary tool developed by the authors was proposed. Two types of burnishing process experiments were conducted using the tip-burnishing process to deburr the workpiece edge and create a sharp cutting edge. Furthermore, an evaluation test for the cutting performance of the sharp edge, which was treated using the developed burnishing process, was conducted. In the deburring experiment, superior deburring was achieved by generating a sliding effect orthogonal to the burr generation direction. An experiment was conducted for evaluating the sharpening of the cutting edge; it was observed that the cutting-edge angle decreased due to the burnishing process. A cutting performance test was conducted using a wedge-shaped workpiece before and after burnishing. The cutting performance of the workpiece was quantitatively evaluated based on the load and stroke required for the cutting of the sheet material.

Abstract: Remote sensing image registration system has been widely applied for agriculture, forestry, geology, ocean, meteorology, hydrology and military field, which studies image correction, enhancement and registration based on digital image processing technology. This paper presents system design and realization of registration technology for remote sensing image. Remote sensing image has geometric distortion and needs digital correction by adopting polynomial method at first. Then five kinds of technology are offered to enhance the contrast of remote sensing image including histogram enhancement, grey level transformation enhancement, image smoothing, image sharpening and pseudo color enhancement. Image geometric registration algorithm is carried out to fuse images of the same area acquired at different times on different wave band at last. Test result shows that the method presented has good accuracy and quick speed for realtime application.

Abstract: Tool logistics is expected for economic and just-in-time production, whereas expensive machine tools require instantly available supplies of the right cutting tools. In this context demand for high tool availability is a need to reduce non-productive times by shortening tool`s set-up times. A solution of the tool logistics depends on a level of automation and integration of manufacturing systems. The article presents current state of the tool logistics system established on the intelligent technologies. It applies general solutions in tool logistics system in the Centre of Excellence of 5-axis Machining at Faculty of Materials Science and Technology in Trnava. There are described some important processes and equipments for their implementation.

Abstract: In this paper, the characters of the 5-axes NC grinding machine for the drill point MK6335 are introduced. The attributes of Ni Zhifu drill (Chinese multi-facet drill-CMFD) are stressed. The sharpening key technology for the Ni Zhifu drill point in this grinding machine is stated. By using the grinding machine and the key technology, the CMFD can be ground accurately. After ground, the geometric angle error of the drill point is less than 1 degree.
