In order to solve complex decision-making problems, MCDM has recently known a fast development. One of the main differences between the decision models consists in the way of evaluating the numeric and the non-numeric data that interfere while solving a problem. If the number of the criteria is not high and the evaluation contains both quantitative...

Jerk, as the derivative of acceleration, is used more and more in the kinematic study of the systems characterised by short travels and requiring a high precision of positioning, including elevators, CNC machine tools, and industrial robots. The acceleration modeling using jerk variation serve as a basis for generating the functioning tahogrames of...

The toroidal cutting edge, also called corner cutter, is a combination of the cylindrical-frontal milling cutter and the spherical head milling. The paper follows at generating the optimal trajectory for making the finished product with the toroidal cutting edge without having to use the flat end mill and the ball nose end mill. This trajectory is ...
