  1. 1. Modeling of Energy Consumptionin Milling Process to Assess their Environmental Impact

    University essay from KTH/Produktionsutveckling

    Author : Vasanth Kumaran Ashok Kumar; Peng Liang; [2023]
    Keywords : Milling process; Energy consumption; Mechanistic model; Environmental impact; Life cycle assessment; Fräsningsprocess; Energiförbrukning; Mekanisk modell; Miljöpåverkan; Livscykelbedömning;

    Abstract : This thesis presents a method for modeling energy consumption in the milling process to assess their environmental impact, using a simple experimental approach. The factors influencing the environmental impact in milling processes are analyzed with life cycle assessment principles, and their climate change impact is calculated with examples of dry milling experiments.

  5. 4. CNC Engraver : Precision and flexibility of a miniature CNC engraver

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Rasmus Booberg; Martin Borgén; [2022]
    Keywords : CNC; Engraver; Arduino; diamond drag bit; GRBL; CNC; Gravyrmaskin; Arduino; diamond drag bit; GRBL;

    Abstract : This report documents the design and construction of a computer-controlled engraver (CNC engraver). Whereas most common machines used for this purpose are dimensioned towards milling, this project aims to create a dedicated engraver which could be of reduced size and complexity in comparison to standard CNC routers.

  6. 5. A novel approach for the improvement of error traceability and data-driven quality predictions in spindle units

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Adithya Rangaraju; [2021]
    Keywords : Machining; component degradation; condition monitoring; data-driven quality control.; metallskärning; komponentnedbrytning; data-driven kvalitetskontroll.;

    Abstract : The lack of research on the impact of component degradation on the surface quality of machine tool spindles is limited and the primary motivation for this research. It is common in the manufacturing industry to replace components even if they still have some Remaining Useful Life (RUL), resulting in an ineffective maintenance strategy. READ MORE
