Introduction
For the manufacturing of support plates it is necessary to start from the plane shape of the work piece, type of the material, conditions established through design and dimensions of the piece.
Industrial processing of the plates uses plasma or laser cutting for large plates from different materials (steel, copper, aluminum) but the costs of the acquisition and maintenance of these devices used in processing are higher.
All these factors are presented in the next formula: C= Cm+Csc+Co+ Cdt+ Ctdv (1) where: · C – total costs inquired for the fabrication of the product; · Cm – costs of the materials: it means the taking into account specific factors as the planar surface area, thickness of the material, specific weight of the material, specific coefficient related to the utilization of the material and cost per unit of the material; · Csc – costs with staff meaning net salary and other legal charges (social charges, state budget, etc.), average time per operation for the production of a single unit, average time for preparing the devices for a proper functioning and the number of products · Co – costs with overheads: it means the taking into account the costs related to the consumption of the electrical energy, water, technical gases and other specific conditions required by the process; all these factors can be summarized as 2 – 2,5 % from staff costs · Cdt – costs with the depreciation

Therefore, in order to reduce the bending deformation and improve the measurement precision, some methods were put forward as follows:
(1) The original material of transmission set, which loads radial measurement device and axial grating measuring device head, were changed, using LY12 instead of Q235-A, and the self-weight of the ontology could be reduced to the third of original;
(2) In the cases of unaffected measurements, transmission set would be got rid of parts appropriately.
