Patent number: 7690127Abstract: An apparatus for checking the diameter of crankpins of a crankshaft in the course of the machining in a grinding machine includes a Vee-shaped reference device, a measuring device associated with the reference device and including a feeler axially movable along the bisecting line of the Vee-shaped reference device, and a support device with a first arm rotating with respect to a support arranged on the grinding-wheel slide and a second arm rotating with respect to the first and carrying the Vee-shaped reference device. A guiding mechanism includes a limiting device, with mutually abutting surfaces and coupled to the support device, that guides the displacement of the reference device along a trajectory substantially parallel to the profile of the grinding wheel, allows the engagement of the reference device on a crankpin to be checked while the latter is orbitally moving, and does not interfere with the displacements of the support device caused by the orbital motion of the crankpin in the checking condition.Type: GrantFiled: November 10, 2008Date of Patent: April 6, 2010Assignee: Marposs, S.p.A.Inventors: Carlo Dall'Aglio, William Montanari

Patent number: 7437263Abstract: A method and a relevant apparatus for controlling the machining of a piece (18,38) rotating in a numerical control machine tool (33) includes the steps of detecting instantaneous values (V(i)) indicative of the dimensions of the piece during the machining, performing dynamic processing of the detected instantaneous values and controlling at least one machining phase on the basis of the processing. The method includes dynamic calculation of average values (M(j)) of sequences of the detected values, acquisition of a variation index (P) indicative of the average values trend during the machining and of a correction coefficient (K) that allows for the delay of the calculated average values with respect to the actual dimensions of the piece, and processing of an instantaneous dimension (RI) of the piece that is transmitted to the numerical control of the machine tool for controlling the machining.Type: GrantFiled: June 1, 2005Date of Patent: October 14, 2008Assignee: Marposs Societa′ per AzioniInventor: William Montanari
