Optimisation of Single Edge Tools Exploitation Process

Paper show possibilities to optimization of exploitation process of single edge tools. It decrease cost of machining using optimizing the use of the cutting edge. This possibility was presented for single edge tools in oblique and orthogonal cutting. In oblique cutting was presented optimizing the use of the cutting edge by partially exchange of active section of the cutting edge. It is shown for straight edges. Presents model of special tool and result of made experiments, which shows possibilities to increase tool life. Second presented possibilities is orthogonal cutting with round insert. Presented results of calculations of number cutting edges from one round insert by optimizing the use of the cutting edge. For orthogonal cutting was used normal market construction tools for round inserts. Presents first results of surface roughness for tools with worn up cutting edge and rotate for exchange this worn up fragment of cutting edge. In this case number of edges cutting insert increase many times. This can many times reduce the cost of tools in cutting especially in turning.
