Osai SAI designed and developed a new CNC control platform, Open-Xli, a modular system with servo controlled axes and I/O modules distributed on a digital fieldbus.

“OSAI manages high speed machining,” the company said in a statement. “With the advent of extremely rigid machines, the machining of profiles as a sequence of linear micro-interpolations is not ideal. There are two possible ways of solving the problem, by either regulating the dynamics of the movement or the geometry of the trajectories.

“Typically, CAD/CAM systems are capable of providing machine coordinates directly, by processing the data that describes the surface to be milled. This means that the programs normally generated by CAD are closely dependent upon the geometry of the tool and in the case of machining five coordinated axes, the kinematics of the machine.

“With the ability to process 12,000 program blocks of five-axis motion every second, OSAI can manage either the dynamics of the movement or the geometry of the trajectories, it is either a question of filtering the actuation of the commands, creating a ‘soft’ output to the servomotors, without changing the programming concept based on microscopic straight lines, or revolutionizing the programming method, by interpreting the programmed values as a set of points to be approximated in the best possible way.”
