Spremljanje procesa injekcijskega brizganja in merjenje plastičnega izdelka s 3D skenerjem

Urankar, Gregor (author), Kramar, Davorin (mentor)

V diplomskem delu so predstavljeni načini zajemanja oblike geometrijskih teles in opisan postopek digitalizacije merjenca s 3D skenerjem s strukturirano svetlobo. Obravnavani so vplivi na merilni rezultat s poudarkom na določevanju poravnave skeniranega oblaka točk in nominalnega 3D modela ter izbire ustreznih merilnih postopkov. Izvedeno je spremljanje procesa injekcijskega brizganja plastičnega izdelka skozi tri serije brizganja. Namen je ugotoviti zaznavnost sprememb pri orodju ob pogostem menjavanju na stroju za brizganje v treh serijah. Drugi namen je ugotoviti zaznavnost sprememb pri različnih pogojih brizganja, konkretno dodajanja deleža zmletega odpada v osnovni material. V zaključku je predlog za uvedbo tovrstnega načina kontrole v redno proizvodnjo na podlagi pridobljenih rezultatov.

• Title: Injection molding process control and product measuring with 3D scanner

Abstract

This final degree presents the ways of capturing the shape of geometric bodies and describes the process of digitalisation of the part with a structured light 3D scanner. The effects on the measurement result are analyzed, focusing on the alignment of the scanned cloud points and the nominal 3D model and the selection of appropriate measurement procedures. The process of injection molding of the plastic product was monitored through three series. The purpose is to determine the detection of changes in the tool with frequent control. The second purpose is to determine the sensitivity of changes in different conditions, specifically adding the percentage of recycled material to the base material. In conclusion, there is a proposal to introduce this kind of control into regular production, based on the results.
