Results of the performed works at calibration of the metal-cutting machine are given in article. The technology of performance of control is considered. The conclusion in which it is noted that laser trackers including the measuring Vintag vehicle produced by Faro firm, possess high efficiency of the solution of problems of calibration is made. Their software has an opportunity to carry out processing of results of measurements and preparation of reports directly on the platform of performance of work and to give results on the place. To provide the accuracy of measurements of the spatial coordinates of 0.005-0.01 mm at distances to 10000-15000 mm. All these characteristics allow to recommend to machine-building enterprises use of such and similar measuring cars for the solution of problems of calibration of metal-cutting machines.

the article presents the study in the control of the geometric parameters of wheels of cranes circular steps. The options considered to determine the radii of the wheels by indirect methods, of which the most effective are those based on the construction of the measuring triangle at the open part of the forming. As the final results and proposals noted the following: both control provide almost ravnovesnye results definitions of the geometric parameters of the wheels; more universal is the way to control the radius of the wheel, using calipers and this method is recommended when addressing these and similar problems.

The main maintenance of a diversification of production as activity of subjects of managing is considered. being shown in purchase of the operating enterprises, the organizations of the new enterprises, redistribution of investments in interests of the organization and development of new production on available floor spaces. The most important organizational economic targets of a diversification of management are presented by innovative activity of the industrial enterprise.

Keywords: diversification of management, production diversification, financial and economic purposes of a diversification, technological purposes of ensuring flexibility of production

The problem of measuring the geometrical parameters of objects with curvilinear forms, is that for some material object it is necessary to determine the compliance of its controlled surfaces specified a priori (or a posteriori) geometric form. A common solution to this problem lies in the fact that in some coordinate system is set to reference the shape of a curved shape (circle, ellipse, parabola, hyperbola and other curves), it is necessary to determine whether the current point of the controlled object to a given curve.
