A review of recent developments in the design of special-purpose machine tools with a view to identification of solutions for portable in situ machining systems

Intelligent Analysis of Utilization of Special Purpose Machines for Drilling Operations

“…The field of machine tools for generating singular products is well documented; however, the area of specialist machines for dedicated tasks has received less attention (Allen et al, 2010). This is particularly true for modular SPMs that are a new addition to the family of SPMs (Tolouei-Rad and Tabatabaei, 2005).…”

Overview of Mobile Machine Designs for Large-Sized Products

“…Следовательно, во многих случаях происходит неэффективное использование ресурсов. Практический подход к решению проблемы -использование небольших мобильных установок для выполнения таких операций механической обработки [4][5][6][7]. Эта концепция преследуется по двум аспектам.…”

Towards automated damage detection for in-situ remanufacturing

“…However, this model is not feasible for our focus of remanufacturing, Chapter 1: Introduction where the parts are typically large, like that found in marine and offshore structures (see Figure 1.1). To disassemble and transport large parts from such structures to an off-site remanufacturing factory is time-consuming, expensive, labour intensive, and potentially dangerous [9,10]. Additionally, some parts are impractical to remove due to physical constraints, requiring excessive structural changes, like the crankshaft crankpin journal in a ship [11,12].…”

“…To harness the societal and economic benefits of remanufacturing, there is an emerging necessity for automated in-situ remanufacturing, to reduce the labour related problems due to the labour intensiveness of traditional remanufacturing via automation, and to remanufacture parts typically too large to transport cost efficiently, or impractical to remove due to physical constraints [9][10][11][12], by carrying out remanufacturing in-situ. To be able to implement such an automated in-situ remanufacturing for the marine and offshore industry, there are a number of challenges that has to be addressed.…”

“…By automating remanufacturing, there would be a decrease in dependency on skilled labour, increased safety, reduced turnaround time and material used, as well as increased repeatability and reliability, all of which would lead to cost savings in the remanufacturing process. In addition, there is a need to carry out the remanufacturing in-situ for industries where parts are typically too large to transport cost efficiently to off-site remanufacturing factories, or impractical to remove due to physical constraints, like that found in the marine and offshore industry [9][10][11][12]. This would omit the need to disassemble and reassemble, thus further reducing labour dependency, turnaround time, and costs.…”
