MACHINE-TOOL AND CUTTING TOOLS PRODUCTION

Shirshov А. G. — Construction method improvment of the power displacement behavior for the machines elastic-friction systems

A question of the accuracy and productivity assessment is raised at a design stage of the machine tool. There is an assessment methodology of the machine tool rigidity and accuracy at a design stage, but manual calculation through the use of this methodology will occupy not less than one-three months and therefore its automation is required. At calculation process machine tool structure is bring to the elastic and frictional system consisting of modules. Each module is responsible for elastic and inelastic resistance of the structure which becomes apparent in common.
For each module it is necessary to consider displacement as external force function and bring displacement to the cutting tool top so that may to define the machine tool rigidity, the rigidities balance and the weakest designs link on rigidity. As there is a lot of modules, it is necessary to calculate force displacement very quickly. The graphical representation of the force displacement dependence as external force function is called the characteristic of force displacement (CFD). In article the existing approach to CFD creation and determination of the force displacement values is considered and new approach is offered.
Key words: machine tool rigidity, machine tool accuracy, force displacement, force displacement characteristic, calculation automation

Shiganov I. N., Usov S. V., Melnikov D. M. — Operational control of the lubricant viscosity index for maintenance of the machines and mechanisms efficiency

The lubricants characteristic gradually worsen during machines and mechanisms exploitation therefore operating control of this characteristic represents an important task. One of the key parameters influencing the lubricant efficiency is the viscosity index determining oil properties change degree in case of temperature change. The express control of a viscosity index may permit to reveal timely critical breach in lubricant work and to avoid both mechanical damages of the rubbing elements and an uneconomical expenditure of oils. The offered control method of an oil viscosity index is based on a laser phase analysis method — research of material optical properties change in broad range of temperatures. The method can be used directly on equipment exploitation places that is especially actual for the equipment which is used in conditions with the increased impurity.
