One of the important and still current problems occurring in the fish processing industry is the intensive wear of the cutting surface of industrial cutting blades used to separate the fish raw material. In the paper, the proposes aproprietary solution to the above problem consisting in the regeneration of worn surfaces realized in the process of precise grinding by the use of a prototype 5-axis CNC grinding machine was presented. The obtained machining results were verified, among others on the basis of measurements of values of the cutting edges inclination angles and analysis of values of selected surface roughness parameters. The proposed solution along with the developed methodology can be an interesting alternative to typical ways of renewing the cutting ability of cutting tools in applications from the fish processing industry.

The analysis of surface roughness of extruded aluminium profiles.

This paper reports work covering the variation in surface quality in the extrusion of AlMgSi aluminium hollow sections incorporating different extrusion conditions. AlMgSi alloys are the most commonly used alloys in extrusion industry because of its wide range of function. They are used in buildings for constructions that should have a good surface quality. The total geometry can be considered to be split-up into three components-roughness, waviness and form. In this article Ra and Sm were chosen for considerations. Measured volumes quite good describe surface and are the most commonly used to determining roughness' level. The article will be making an attempt to explaining relationship between surface quality and some extrusion parameters.
