Keermete freesimine on tootmis tehnoloogia, kus tehnoloogia valik sõltub materjalist, keerme omadustest ja tootmisnõuetest. Käesolev töö keskendub keermefreesimise tehnoloogiale, mis sobib erinevate keermegeomeetriate loomiseks, pakkudes eeliseid võrreldes traditsiooniliste keermestusmeetoditega, eriti väiksema lõikejõu ja tööriistade universaalsuse osas.
Töö eesmärk on uurimustöö põhjal luua õppematerjal, mis toetab keermefreesimise tehnoloogia õpetamist Eesti Maaülikooli lõiketöötlemisega seotud õppeainetes.
Töös kasutatakse tehnilist kirjandust, CNC-töötlemise juhendeid ja praktilisi katseid, sealhulgas keermefreesimise katseid erinevate lõikeparameetritega ning NC-koodi loomist nii generaatorite kui CAM-tarkvara abil.
Tulemused näitavad, et keermefreesimine võimaldab toota keermed ka piiratud spindlivõimsusega seadmetel, kui kasutada sobivaid lõikeriistu ja lõikeparameetreid. Katsete käigus võrreldi erinevaid tööparameetreid ja nende mõju keermete kvaliteedile. Töös loodud õppematerjal sisaldab teoreetilist osa, praktilisi juhendeid, visuaalseid skeeme ja näidisülesandeid, mis toetavad õppijate arusaamist ja oskuste kujunemist. Materjal on rakendatav nii kutseõppes kui ka tööstuspraktikas ning pakub tuge NC-koodi ja CAM-süsteemide kasutamisel keermefreesimise protsessis.
Thread production is a machining process, where the choice of technology depends on the material, thread characteristics, and production requirements. This thesis focuses on thread milling technology, which is suitable for creating various thread geometries. Compared to traditional threading methods, thread milling provides advantages such as lower cutting forces and the ability to use a single tool for multiple thread sizes. The aim of this thesis is to develop educational material to support the teaching of thread milling in machining-related courses at the Estonian University of Life Sciences. The study utilizes technical literature, CNC machining manuals, and practical experiments, including thread milling tests with different cutting parameters and the generation of NC-code using both code generators and CAM software. The results demonstrate that thread milling enables the production of threads even with limited spindle power, provided that appropriate tools and cutting parameters are used. The experiments compared different machining parameters and their effects on thread quality. The developed educational material includes theoretical content, practical guides, visual diagrams, sample tasks, and CNC programming examples to support learners’ understanding and skill development. The material is applicable in both vocational education and industrial practice and emphasizes the use of NC code generators and CAM systems to automate the thread milling process.
