Skozi čas so se v strojništvu vse bolj začele uveljavljati alternativne tehnologije oblikovanja kovin. Ena izmed pomembnejših je rezanje z abrazivnim vodnim curkom (AWJ). Uveljavitev novih tehnologij je privedla do novih težav, ki jih je potrebno odpraviti. Zaradi abrazivnih lastnosti vodnega curka med delovanjem AWJ prihaja do abrazivne obrabe šobe, kar privede do spremembe premera in rezalnih lastnosti vodnega curka. Za meritev premera vodnega curka, ki se uporablja za razrez, je potrebna brezdotična metoda merjenja. Zaradi te potrebe po brezdotični metodi smo se odločili, da uporabimo laserski mikrometer. Z željo po bolj natančnih meritvah smo raziskali, kako vpliva merilno območje laserskega mikrometra na rezultate meritev. Rezultati kažejo, da je v specifičnem merilnem območju ta merilna metoda bolj primerna oziroma bolj točna.

• Title: The water jet diameter measurement dependence inside measuring range of the laser micrometer

Abstract

Over time, alternative technologies for metal forming have become increasingly used in mechanical engineering. One of the most important is abrasive water jet cutting (AWJ). The introduction of new technologies has led to new problems, which have to be eliminated. Because of the abrasive properties of the water jet, comes during the operation of the AWJ to the accumulation wear of the nozzle, which leads to a change in diameter and cutting properties of the water jet. To measure the diameter of the water jet, used for cutting, touchless method of measurement must be used. Because of a need for this method, we decided to use the laser micrometer. We wanted our measurements to be accurate, so we researched, which effect has the laser micrometer area on the results of measurement. The results show that this measuring method is more appropriate and accurate in a specific measuring area.
