Nikitina L.G. Methods of measurement of parts on CNC machine tools

Methods of measurement of parts on CNC machine tools

Nikitina L.G.

We consider the ways and methods of measurement of parts on machine tools. Depending on the type of production is following methods of measurement on machine tools: measurement during processing and measurement under interrupted processing. When using the “measurement in processing” automatically measured geometrical and technological parameters of the cutting process in the case of deviations from the nominal values produced is automatic adjustment of the cutting process. Way to measure “in the interrupted processing” is used in cases where the parts have complex geometry and the machine handles a wide range of parts in small batches, which fully complies with the conditions of processing on CNC lathes. The choice of method depends on the measurement method of processing, measurement conditions, the required accuracy of measurement, the size of the party details and their nomenclature, the type of machine and the degree of automation.

Keywords: measurement methods, techniques, cutting machine, adjusting the quality of the product.

Kokoreva O.G. Increase of durability of heavy-duty machine parts of surfaces static-pulse treatment

Increase of durability of heavy-duty machine parts of surfaces static-pulse treatment

Kokoreva O.G.

Offered for practical use in production the new method of statiс-pulse hardening of hard loaded surfaces has a number of essential advantages in comparison with applied now. Distinctive feature of a method is the combination of static and dynamic processes of processing as a result of which necessary qualities of a blanket of a processed detail, and as necessary hardness and residual tension of compression are provided. This way of hardening is one of more effective, energy saving and easily realized in production. Static-pulsed hardening increases the number of controlled design, tuning, and technological factors that affect the result of hardening. As a result, the static-pulse processing provides reduced surface roughness, increased wear resistance and hardness of the surface layer by increasing the depth of hardening and changes in the microstructure of the metal. For the static-pulsed hardening is characterized by high performance and low cost compared with heat treatment and explosion.

Keywords: static-pulse treatment, hardening the surface, quality characteristics of the surface layer, reliability, durability.

The purpose of this work is to establish research methods mechanical systems with «not holding» ties. The problems of determining the mode of continuous flying up of a material particle from surface oscillations with the force of gravity are considered. The graphical-analytical method for determination of the mode parameters is realized. The analytical characteristics of the relations between the basic modes of continuous flying up of a particle as a function of the parameters of the surface vibrations are identified. The proposed methodological framework can be used to research the mode of continuous flipping with additional constant force which operate from the external environment in free flight phase.

Keywords: not holding ties, interaction of a material particle with a vibrating surface, a mode of a material particle tossing with one contact.
