20.500.12556/DKUM-54325 Optimizacija plazemskega razreza v podjetju Pozitron d.o.o. Optimization of plasma cutting in Pozitron d.o.o. company V raziskovalni nalogi sem opisal podjetje Pozitron d.o.o., ki je usmerjeno v maloserijsko proizvodnjo. Predstavil sem njihove izdelke in pol izdelke. Zajel sem nastanek obloka in delovanje plazme. Kasneje sem opisal njeno delovanje in kateri plini se uporabljajo pri rezanju. Navedel sem tudi asistenčne pline, ter različne postopke rezanja. Zaradi pomanjkljivosti tega postopka, smo se glede na posvet direktorja odločili, da optimiramo plazemski in plamenski postopek, ter stroške razreza za eno delovno uro. V diplomskem delu sem navedel stroške optimiranja plazemskega postopka na CNC stroju. V nadaljevanju še prikažem CNC stroj, njegovo delovanje in primerjavo rezov med optimiranima postopkoma. Prikazan je tudi termični prerez materiala, rezanega s plamenskim postopkom in plazemskim postopkom. Za konec dodam primerjavo hitrosti rezanja med postopkoma na enakem stroju. In the diploma work, company Pozitron d.o.o., which produces small-series products, is described. Also their products and semi products are presented. In the work, formation of plasma and arch is also included. Later the principle of plasma cutting and types of gases used by plasma cutting are described. Also assisted gases by plasma cutting and different types of cutting are described. Owing to weaknesses of plasma cutting our company decided to optimise process of plasma cutting and arc cutting, and combine cutting costs per one working hour. In diploma work also optimisation of costs of plasma cutter installed on CNC machine are presented. In continuation CNC machine, its operation and comparison of cuts by both optimised processes are shown. Also comparison of both cross cuts, arc and plasma cuts are shown. In conclusion the comparisons of cutting speeds by both processes on the same machine are shown. programiranje G-koda plazma optimiranje Programming G-code plasma optimisation true true false [A.
