It kind of feels tough to think, yet mathematicians weren't drawn to integration difficulties on infinite-dimensional nonlinear constructions as much as 70s of our century. no less than the writer isn't conscious of any ebook referring to this subject matter, even though as early as 1967 L. Gross pointed out that the research on limitless dimensional manifolds is a box of analysis with really wealthy possibilities in his classical paintings [2.

The gravimetric method is the standard method used by both National Metrology Institutes (NMIs) and accredited laboratories to calibrate high accuracy volumetric equipment. The method consists on weighing the standard volume measure when empty and again when full up with water (the calibration liquid) to the reference line. The difference obtained in the weighing gives the mass of contained or delivered liquid, which is then converted to volume using the appropriated formula described in the ISO 4787 standard .

Principal step of model correction. e. form defects), between nominal surface and measured points, calculated after alignment stages are necessary for correcting the errors cumulated during the manufacturing phase . An industrial application, concerning a rapid prototyping technology process, is presented for validation of this approach. As already pointed out, the prototyping technology is used for manufacturing a physical model starting from a STL format file obtained by Computer Aided Design (CAD) software.
Conclusion The mechanical productions of freeform surfaces are being a current practice in the industry. The conformity problem of the mechanical parts is felt more and more. The objective of the present work consists to propose one mathematical procedure for modelling and inspecting freeform surfaces. This proposal allows correcting deviations within manufactured parts. This procedure is built on two algorithms. The first algorithm is used for alignment between the measured points and the CAD model.
