Response of a numerically controlled machine-tool to the modification of its position feedback using real-time solution
The dimensional accuracy of machined parts can be influenced by numerous factors, among which inaccuracies in the machine’s structural loop and thermal expansion of components have the biggest impact. Hence, highly accurate machining requires effective error compensation. This motivates the development of a real-time compensation system implemented...
Moringa Connect: Design and Fabrication of the Drum for a Moringa Leaf Dryer Prototype
Moringa Connect, founded in 2013 by MIT alumnus Kwami Williams, supports over 5,000 African farmers, primarily in Ghana, by providing a direct sales, manufacturing, and shipping platform for nutrient-dense moringa leaves. Despite significant social and economic benefits for the local farmers, the current drying process in Accra, Ghana, is inefficie...
Sensitivity analysis of dry machining using a Life Cycle Assessment approach
Manufacturing processes, particularly machining operations, contribute significantly to the environmental footprint of the industrial sector, primarily driven by the consumption of critical resources such as lubricants, tools, and electrical energy.

Effect of Hygrothermal Conditioning on the Machining Behavior of Biocomposites
This work aims to study the cutting behavior of biocomposites under different controlled hygrothermal conditions. This investigation choice is motivated by the fact that natural plant fibers such as flax are characterized by their hydrophilicity which makes them able to absorb water from a humid environment. This absorption ability is intensified b...
Diagnosis of spindle failure by unsupervised machine learning from in-process monitoring data in machining
In High Speed Machining (HSM), process performance is closely linked to the optimization of cutting conditions and spindle exploitation. Keeping high levels of productivity and machine availability with limited costs is important. However, machining incidents, such as abnormal vibration or tool failure, can cause spindle failure and machine downtim...
