Advantages of the CCD Camera Measurements for Profile and Wear of Cutting Tools

In our paper we prepared an evaluating study of which conclusions draw mainly two directions for our fields of research. On the one hand, this means the measuring of fix, standing workpieces, on the other hand this means geometrical measurement of moving tools. The first case seems to be solved in many respects (in general cases), but the second one is not completely worked out according to the relevant literature. The monitoring of tool wear, the determination of geometrical parameters (this is mainly in case of gear-generating tools) is not really widespread yet, mainly, if optical parameters have influence on the evaluating procedure (e.g. examination of profiles of grinding wheels). We show the elaboration of a process for the practical application of measuring techniques performed by image processing CCD cameras on the basis of wearing criteria of different cutting tools (drilling tool, turning tool). We have made a profile and cutting tool wear measuring program.

Applying Projective Geometry in Design of Worm Manufacturing

The mathematical describing of the production process in mechanical engineer work in the euclidean space model and the base of the analytical describing of the projective space model is practically identical in the form, which makes it reasonable to discuss of the production geometry to approach of the projective geometrical negotiation in the . It is a fact that in one of the cases, using the approach of a projective geometrical connection and the mathematical-kinematical model resulted in expansion in the field of production precision, specifically considering the examination of the production of the conical worm by grinding wheel. The abstraction of the production geometry on projective space model has a few results in case of conical worms. The elliptical errors in production of the conical worm with arched or anything profile by grinding wheel can be eliminated by this method way to achieve the constant pitch, the torsion of profile and others.

Up to Date Mathematical Model for Analysing of Cylindrical Worm Power with Bevel-Gear

The developed general mathematical-kinematical model for examination of mating of cylindrical and conical helicoids and their tools - furthermore the helicoids surfaces are on identical axis -, which is suitable to deal with examination at the same time. This paper shows the newest mathematical-kinematical model to analyzing the mating of cylindrical worm gear with bevel gear.
