The classic scheme
Calculations are carried out after the design stage, with the risk of numerous iterations if the pieces are incorrectly sized.
Thanks to its knowledge of mechanical design, calculations and manufacturing, NUMESYS provides informations on possible improvements, taking into account industrial constraints.
Design assistance
NUMESYS can be involved from the pre-project or study phase to choose the right architectures and their dimensions, reducing the number of iterations in the design phase and saving time and money in the process.
