Tekom razvojnega procesa novega izdelka običajno pride do večih sprememb, vsaka sprememba pa terja tudi izdelavo vzorcev, ki morajo karseda natančno posnemati načrtovan serijski izdelek. Stremimo torej k natančni in ponovljivi izdelavi vzorcev, ki omogoča evalvacijo načrtovanega produkta in načrtovanje proizvodnih procesov potrebnih za serijsko izdelavo produkta. Z ozirom na to smo v okviru zaključne naloge zasnovali in izdelali ročno orodje za izdelavo prototipov paketov lamel potrebnih za izdelavo statorja električnega pogona. Za zagotavljanje ponovljivosti pa smo tudi preverili vpliv moči in hitrosti laserskega reza, ki je uporabljen za izdelavo lamel prototipov, na odrezane lamele, natančneje na stanje robov. Zasnovano orodje omogoča natančno izdelavo paketov brez večjega zamika lamel levo in desno izven idealne lege, rezultati testov za preverjanje vpliva moči in hitrosti na rez, pa so pokazali le omejen uspeh pri izboljšanju stanja robov.

• Title: Ensuring the quality of laser cutting and manual assembly of lamella packages

Abstract

During the development process of a new product the designs encounter numerous changes, each one requiring prototype to be made, which needs to resemble the planned mass-produced products as much as possible. Thus, we strive to produce accurate and repeatable prototypes, which allow evaluation of the planned product and planning of the production processes needed for mass production. With regards to that we have within this final thesis designed and made a tool for producing prototypes of lamination stacks needed for a stator of an electric motor. We have also, with intention to ensure repeatability, checked the effects of laser cutting speed and power on the condition of cut edges of the lamellas, as laser cutting is used to produce them. The designed tool allows for accurate production of laminations stacks without major misalignment of the lamellas. However, the results of the tests intended to check the effects of laser cutting speed and power on cut edges showed only limited success at improving the quality of the edges.
