Definitions

  • the present invention relates to a manufacturing method for the diamond dressing process to be performed on items, according to the preamble of claim 1, as for example known from IT VI20 130 168 A1 .
  • This processing method consists in the controlled removal of limited amount of material so as to create micro-concavities, so-called “notches”, to give the processed surface a particular shine, deriving from the different refraction of the light rays that are reflected by the multiplicity of appropriately oriented micro-surfaces obtained on said surface.
  • the virtual configuration of the overall shape of the item or surface to be diamond dressed, when this operation does not comprise the entire item is communicated to an "axis control" unit, which controls a gripper to which the item is hooked, such as to make the gripping points of the item to be processed coincide on the spindle, as well as to regulate the movements of the tool which engraves the surface to be dressed.
  • the Italian patent document 0001424842 is cited, wherein the "virtual" conformation of the entire total extension of the surface to be dressed is detected directly on the item to be processed and to be communicated to the "axis control" unit, said conformation being obtained through a three-dimensional detection on the item itself.
  • Object of the present invention is to improve the method described in the document cited above.
  • object of the present invention is to implement the above-mentioned known method, so as to make possible the realization of the same diamond dressing on all the items of the same series, i.e. those which have an identical shape, said diamond dressing being perfectly equal to that realised on the sample item and being considered by the operator the best possible diamond dressing that can be realized.
  • a further object of the invention is to reduce the diamond dressing time of each item; in any case, considering that in every diamond dressing series hundreds of identical items are processed, the savings of a few seconds on each item processing allows, at the end of the entire operation, a considerable gain in terms of productivity.
  • the orientation of the holes or hold points in the space is detected and the data collected are sent to the CPU, which orients the manipulator gripper that retains the item, such that said item is positioned exactly in the "gripping points" of the spindle, defined with the processing of the first item; therefore, the new item to subject to the manufacturing diamond dressing process will be exactly oriented in the holes or "gripping points" which, therefore, are spatially located in the same way as the gripping points of the "sample item".
  • the diamond dressing machine provided with the program for carrying out the manufacturing diamond dressing process according to the invention, initially envisages the realisation of the first item or "sample item” according to the following steps:
  • the novelty feature of the invention concerns the steps of the manufacturing diamond dressing process of the second item and the items following the first, which present a conformation which is only theoretically equal to the first item but, de facto, have minimal differences following the type of processing used for its realisation (moulding, electroforming, micro-casting or other semi-finished product production methods).
  • the entire manufacturing diamond dressing process envisages at the beginning the withdrawal from a warehouse, where the items P 1 , P 2 , P 3 , P n are inserted on a rod, using a gripper K, of the first item to be dressed P 1 (see fig. 1 ), to be positioned between the heads of the spindle M (see fig. 2 ), to be processed, through the tool S, which detects the spatial coordinates using, as a reference, the "Euler angles" (see fig. 4 ) and finally subjected to diamond dressing through the tool U (see fig. 3 ) to obtain the final diamond dressing PK 1 (see fig. 5 ).
  • the manufacturing diamond dressing process continues with the removal from the warehouse, using the gripper K, of the second item to be dressed P 2 (see fig. 6 ), which is positioned exactly in the "gripping points" T, defined during the diamond dressing of the first item P 1 or “sample item” and then, through a scanner or other detection systems Z, is subjected to the three-dimensional scanning of the surface on which the diamond dressing pattern or "sample pattern" is brought, memorised by the first item or "sample item” (see fig. 7 ), and finally subjected to the diamond dressing using the tool S (see fig. 8 ) to obtain the final diamond dressing PK 2 (see fig.
