  1. 1. A deep learning approach for drilling tool condition monitoring in Raiseboring

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Hedaya Alyousif; [2023]
    Nyckelord :drilling tool condition; deep learning; drilling signals; CNN; spectrogram; Raisboring;

    Sammanfattning : Drilling tool wear can significantly affect the performance of the drilling operation and add extra cost to it. Accurate detection of drilling tool condition is very important for enabling proactive maintenance, minimizing downtime, and optimizing drilling processes. LÄS MER

  3. 2. Installation of cables for monitoring purposes in the ground by using Horizontal Directional Drilling

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Eduardo Garcia Cañas; [2022]
    Nyckelord :HDD; Earth Embankment Dam; Resistivity; ERT; IP; Technology and Engineering;

    Sammanfattning : The median age for Swedish earth embankment dams is about 60 years. Due to its longevity, one of the major concerns is the internal erosion causing increased seepage through the dam, which ultimately may increases the risk for dam failure. To meet this challenge, there is a need for improved monitoring methods. LÄS MER

  4. 3. Detection of tool wear in drilling based on axis position signals

    Uppsats för yrkesexamina på avancerad nivå, Högskolan Väst/Avdelningen för maskinteknik och naturvetenskap

    Författare :Anders Hansson; [2016]
    Nyckelord :Drilling; Tool wear; Continuous monitoring; Internal sensors;

    Sammanfattning : Cutting operations are important and commonly used operations in the field of manufacturing. Automated machining is today commonly used in CNC-machines. One common drawback with automated machining is that the tool condition is challenging to predict which leads to a conservative tool replacement times. LÄS MER
