  1. 1. Cooling Strategy Influence on Temperature in ETD Center

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Oskar Edinger; [2021]
    Nyckelord :Machining; Drilling; Exchangeable tip drill; 316L Stainless steel; Thermocouple; IR Thermography; Skärande bearbetning; Borrning; Löstoppsborr; 316L Rostfritt stål; Termoelement; IR Termografi;

    Sammanfattning : Striving for increased productivity while maintaining hole quality and high process robustness when drilling requires knowledge about the working principles of heat generation, mechanics and a proper cutting fluid that aids in cooling, lubricating and evacuating chips from the cutting zone. If the heat generated in the tool-workpiece and tool-chip interfaces does not exit the cutting zone adequately through the chips, the workpiece material or the redistribution of coolant the hole quality can be impacted negatively and breakdowns may occur which reduces overall productivity.

    Sammanfattning : Internal combustion engines, electric motors and batteries generate a significant amount of heat during operation that needs to be extracted by cooling systems. A cooling system is designed and installed to extract the generated heat and maintain the system temperature in an optimal range. LÄS MER

  5. 4. Optimering av arbetsområde för filtreringssystem

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Simon Altun; [2020]
    Nyckelord :Filtrering; Filter; Vakuumfilter; Spån; Kylvätska; Arbetsområde; Pump;

    Sammanfattning : During the process of cutting metals a coolant is often used for cooling the material being processed and to extend the lifespan of the cutting tool. After the process a mixture of coolant and metal chips remain. In order to separate these from each other vacuum filtration is used. LÄS MER
