Detailed commentComentariu detaliat


The compensation method presented permits not only the obtaining of the optimum corrections at the coordinate measuring system, but also the possibility of machine-tool regulation with measures in coordinate. Thus, by machine (system) regulation


Considering   the uncorrected values of the displacement vectors marked by the coordinate measuring robot (machine) and  the displacement component of the vector  in the coordinate system  aligned after one of the coordinate measuring machine planes (the XY plane and x axis) at the displacement on one axis (axis 3), P0 will move in the coordinate system X,Y,Z with where .


Taking into account the difference between the theoretical position (P0), and real position (PR) of the point which materializes the center of testing spike (probe) in the measuring field owing the static deformation of the structure, it can be determined a correction function for the compensation of this.


For each axis, it is obtained a set of real point deformed which are introduced in the bicubic model of curve. This becomes the particular model of one margins of the coordinate measuring system working zone. The edges of this space are the basis elements to generate the margin surfaces.



1d. What is the time needed for testing?Care este perioada de timp necesară testări?
Time needed for testing, probing and homologation is estimated at about 60 working days.
1e. What is the cost needed for testing?Care este costul necesar pentru testare?
Research costs (testing, validation) are estimated at 1800 Euro.

 For using of specialized software in developing this research theme further research is needed by firms specializing in this field.




Overall assessment of the current stage of technical development.Evaluarea generală a stadiului actual de dezvoltare tehnică
Correspondent to typodimensional (dimensional tip) variant statically analyzed for which are known the deformation values, it is established a correction function for the deformation in the vertical plane and, analogous, for other planes, resulting three correction functions. These functions permit the display of the numeric value corrected, in the vertical axis direction.


For deformation in the vertical plane, it is known the arrow value in the testing spike (probe) position – by analysis of model defined with finite  elements – , which is a polynomial function of v (the distance from the vertical axis origin considered – the limit from left of testing).

It is used a polynomial function with rank 5 correspondent to the deformation dependence of the measuring head position on the traverse (for bridge system).


It is determined, there, the deformation expression .  The correction function for the vertical axis will be:

With this expression for each position of the measuring space, it is established a measuring value corrected by the errors elimination owing the static deformation for that axis.


The graphs of deformation and correction function of the fixe traverse related to the position of the measuring show like in fig. 6.

SECTION 4: Overall Assessment

SECŢIUNEA 4: Evaluare generală



What is you overall assessment of the technical feasibility of the research result?Care este evaluarea generală a fezabilităţii tehnice pentru rezultatul CD?
In practice of compensation of errors caused by deformation of the supporting structure of  measurement systems in coordinates,  the scale of economic effects generated by the new method are as follows:
- increase product quality;
- reduce the launch cycle of product on market. 

The correction function for the vertical axis will be:

With this expression for each position of the measuring space, it is established a measuring value corrected by the errors elimination owing the static deformation for that axis.


The graphs of deformation and correction function of the fixe traverse related to the position of the measuring show like in fig. 6.


In conclusion, the project can be considered to have a minim risk in technical terms;

at the same time, the project has support from some measurement standards bodies.
