Abstract: An apparatus for checking the length (H) of a chamfer (7) delimited by a first surface (5) and by an edge (S), comprises two feelers (15, 25)—movably connected to a same supporting frame (20)—and respective transducers (16,26). The transducers supply signals (T1, T2) indicative of displacements of the respective feelers along mutually perpendicular directions (Y, X). A checking method includes moving the supporting frame at a constant speed so that, during the movement, one of the feelers scans the chamfer and the other cooperates with the first surface. The signals of the respective transducers are acquired and transmitted synchronously to a processing unit (40) which processes them together with information on the mutual position of the two feelers to obtain the length of the chamfer.

Abstract: A method for optically checking by interferometry the thickness of an object (2) being machined comprises a phase of direct checking wherein the spectrum of the result of interference between primary reflected radiations (R1) generated by reflection of incident radiations (I) on an external surface (16) and secondary reflected radiations (R2) generated by reflection on an internal surface of discontinuity (17) of the object is analyzed, and a preliminary phase wherein information relative to the variation of a virtual thickness (D) delimited and defined by a reference surface (18) and the external surface of the object, indicative of thickness variations of the object being machined. In the preliminary phase, the processing is based on the analysis of the spectrum of the result of interference between primary reflected radiations and reference reflected radiations (Rref) generated by the reflection of the incident radiations on the reference surface, that defines the length of a reference optical path.

Abstract: A method and unit for changing the configuration of an automatic machine, whereby a user selects a desired end configuration by means of a selection device, and a display device then displays an orderly list of all and only the operations to be performed on the machine to convert the machine from a current start configuration to the desired end configuration; the list is arranged according to the sequence in which the operations are performed, and for each operation are displayed the state of at least one respective operating value in the start configuration, and the state of the same operating value in the end configuration.

Abstract: A method and automatic machine for processing a product, whereby, from all the regulating and/or monitoring items as a whole, a first group is determined containing a small number of frequently used items having a direct effect on the product; to permit fast use by an operator of the items in the first group, a screen of an interface device displays the items in the first group graphically by means of respective icons, each of which is connected to a synoptic background image showing the function of the relative item substantially in the region in which the relative item is actually effective.
