Multi-parameter surface-quality analysis

Abstract

describes a new method of the surface control. It is a method of surface printing using the SILOFLEX © dental silicone and the subsequent evaluation. The surface-quality control is carried out using profile geometries that are divided into two basic groups. The first group consists of contact devices and the second group consists of non-contact devices. Both of these groups can use 2D-and 3D-measurement options. Subsequently, the surface quality is assessed using the amplitude parameters specified in the standards. These parameters have to be evaluated complexly using the multi-parameter analysis. This analysis is used today by more and more companies and has become an essential part of the control. It is utilized for all the material types from the engineering industry to medicine. The article deals with a non-contact measurement method. It also shows possibilities of an evaluation using the multi-parameter analysis. Keywords: non-contact measurement, replica, surface quality Zadnja leta so bogata na podro~ju metrolo{kih raziskav. Najprej so bile raziskave osredoto~ene na podro~je kontaktnih merilnikov, {e posebej na podro~je kontaktnih profilometrov. Posledi~no z raziskavami in razvojem materialov so ugotovili, da kontaktni profilometri ne zadovoljujejo vseh potreb. Zato so se raziskovalci osredoto~ili {e na razvoj 3D-nekontaktnih opti~nih profilometrov in merilnikov. V tem~lanku avtorji opisujejo novo metodo kontrole povr{ine in njeno evaluacijo. To je metoda povr{inskega tiskanja z uporabo dentalnega silikona SILOFLEX © . Kontrola kvalitete povr{ine se izvaja s profilnimi geometrijami, ki so razdeljene v dve osnovni skupini. Prva skupina vsebuje kontaktne in druga nekontaktne naprave. Obe skupini lahko uporabljata 2D-in 3D-merilni opciji. Naknadno so kvaliteto povr{ine ocenili z amplitudnimi parametri, specificiranimi v standardih. Ti parametri morajo biti ovrednoteni kompleksno in jih avtorji zato imenujejo ve~parametri~na analiza. Ta analiza se danes vse bolj uveljavlja in uporablja v podjetjih kot pomemben del kontrole. Analiza je uporabna za vse vrste in`enirskih in medicinskih materialov. V tem~lanku avtorji opisujejo nekontaktne merilne metode. Prikazujejo pa tudi mo`nosti vrednotenja z uporabo ve~parametri~ne analize.
