Abstract

For the most cases of manufacturing cutting processes in today’s flexible manufacturing systems, the cutting tools which are needed are almost standard. The problem of choosing the appropriate tool shape and dimension is often made by the tool management system according with the shape of mechanical part which must be manufactured. But, the accuracy of profiled surfaces, such as the helical channel of tools depends essentially on three aspects. The first one is the correct determination of geometric profile. The second is the correct execution of that profile. Finally, the third issue is related the positioning of the tool relative to the axis of the blank. The accurate determination of the active profile of the profiled disk milling is an essential constraint, but not the only one to obtain the irregular outline shapes by milling. The settings up parameters are those which supply the closeness of the part spiral shape. The paper presents an iterative analytical calculation procedure for the points from the profiled shape of the disk type of milling cutter. Also, the paper shows a set of analytical expressions for the calculus of the disk type of milling cutter localization parameters, under the condition of rigidity and strength requirement insurance.
