Quality control method for regulating the operation of an electromechanical apparatus, for example an EBM apparatus, in order to obtain certified processed products

摘要

The invention relates to a method for regulating the operation of an electromechanical apparatus (1), for example an EBM apparatus, in order to obtain certified processed products, wherein it is provided an initial calibration step that is intended to check the proper functioning of all the component parts of the apparatus (1) structured to ensure the complete functionality and a subsequent quality control step carried out on the obtained products by the carried out working process. The method entails the following steps:defining a plurality of measurement parameters relating to the component parts of the apparatus;measuring at least some of said parameters by means of sensors and/or measurement indicators related to said parameters during at least one processing phase performed by the apparatus;performing a quality control step on the obtained products after the working process obtaining data on any deviation from the expected quality;comparing the detected measurements of said parameters and data on any deviation from the expected quality with corresponding values of reference parameters available for that specific apparatus and for those products;detecting any deviations in one or more of said parameters or said data with respect to the values of the reference parameters;computing, on the basis of such differences, a total correction and regulation value;applying said total correction and regulation value preferably to only one of said parameters prior to the subsequent process, for example to the generation energy of the electrons beam (3). Basically, the method of the present invention allows obtaining semi-finished products free from structural defects by means of a primary check of the correct functioning of the various component parts of the apparatus (calibration procedure), a secondary check of the operational effectiveness of the process itself (operational qualification procedure) and a further final check of the process stability and repeatability within a process window (performance qualification).
