AI Technical Summary

Technical Problem

Existing methods for straightening cutting blades, particularly circular blades, suffer from manual intervention requirements, lack of repeatability, and inefficiency due to the absence of fixing systems, leading to suboptimal performance and quality.

Method used

An automated system with central fixing of the cutting blade uses sensors, predictive models, and artificial intelligence to determine an optimal hammering strategy, minimizing strikes and ensuring uniformity and precision by constraining the blade in the center and applying controlled hammering on both faces.

Benefits of technology

The system achieves precise and repeatable straightening without manual intervention, reducing the number of strikes needed and enhancing the quality and consistency of the planarity of the blades.

Abstract

A process for straightening a blade, preferably a circular blade, by hammering comprises the steps of: acquiring information relating to the deformation of the blade, including the initial planarity data, by means of sensors; constraining the blade in the centre thereof by means of a controlled locking flange, which allows free rotation about the blade axis; executing a predictive model based on artificial intelligence algorithms to estimate the point variation in the deformation of the blade following each strike as a function of the blade characteristics, the central constraint and the parameters of the hammering already performed; and executing an optimisation system to determine the optimal hammering sequence to be applied on the blade in order to obtain a predefined final planarity profile, thereby minimising the number of hammer strikes and maximising the overall effectiveness of the process.
