Method for measuring operating parameters of a machining of a surface and a device for measuring operating parameters

A method for measuring operating parameters of a machining of at least one surface of a semi-finished component comprising:

• providing at least one measuring device including:
• a frame;
• a fixing system, connected to said frame, configured for fixing said at least one measuring device in an integral fashion with said semi-finished component;
• wherein the frame comprises a central rod having a longitudinal axis of extension and a sleeve, connected to said central rod in a coaxial fashion to the longitudinal axis and containing at least part of the central rod;
• wherein the fixing system comprises a plurality of pairs of arms and a plurality of contact elements connected to the plurality of pairs of arms, one contact element for each pair of arms;
• said fixing system being movable between an operating constraining position, wherein the plurality of contact elements is in a position away from the central rod, and a non-operating position, wherein the plurality of contact elements is in a position toward the central rod;
• wherein the fixing system comprises a ring positioned around said central rod and movable along the longitudinal axis;
• each pair of arms comprising a first arm having a first end and an opposite second end and a second arm having a first end and an opposite second end, said first arm being hinged to the central rod at the first arm first end and to the second arm at the first arm second end, said second arm being hinged to the ring at the second arm first end and to the second arm at the second arm second end;
• preparing at least one group of brushes for machining surfaces;
• preparing a line for the passage of said semi-finished components comprising at least one surface to be machined with said at least one group of brushes;
• preparing a data acquisition and processor operatively connected to said at least one group of brushes and to said line;
• operatively connecting at least one measuring device in an integral fashion with said semi-finished component adjacent to the at least one surface to be machined;
• positioning on said line said semi-finished component to which the at least one measuring device has been operatively connected;
• machining said at least one surface using said at least one group of brushes;
• measuring, using the at least one measuring device, a plurality of operating parameters of the machining performed during the machining step including at least one temperature parameter of the semi-finished component and at least one movement parameter of the semi-finished component;
• sending, by the at least one measuring device, at least one signal representing said at least one temperature parameter and said at least one movement parameter measured during the measuring step to said data acquisition and processor.
