System builders look for software that is both easy to use and powerful; a software that can handle both simple tasks quickly while having the “depth” to be used for more complex scenarios. Usually this becomes a trade¬off between “simple to use” and “very powerful” for
which a solution is not easily found.
Next task will be to show how variables can be used in place of “hard coded” values to facilitate external parameter change. Then conditional branching will be used to call subroutines via a variable change or I/O.
Repeatability and accuracy are important characteristics of any motion control system
and the objective of the system is to assure the desired trajectories can accurately followed through the mechanical range of the system. In traditional XY gantry designs upper gantry member (Y axis) is carried by two identical bottom axes (X1 and X2) ...
Effectively automating any industrial operation, test procedure, or prototype process involving motion requires determining the movement precision needed to yield acceptable results. A motion system ideally positions to a given target point with some small amount of tolerance or uncertainty ...
Almost every task in the production/manufacturing such as, the machining, the packaging, the handling, the storing, the sorting and the retrieving etc. and also, the majority of other non-production related tasks in our daily life are characterized by the controlled motion of workpieces
The majority of the electric linear actuators used in today's industry are of the transmission (converting) type. The rotational motion of an electric motor is converted into linear. The fact that the primary motion is rotary and has to be converted into linear seems, at first glance appears as a disadvantage.
A large majority of the electric cylinder actuators have a screw/nut type mechanism to convert the linear motion into rotary motion. The screw is driven directly by an electric motor or via a gearbox, the nut is connected to a guided rod. Since the nut is guided and cannot rotate, the rod is moving back and forth when the motor rotates the screw.
The question most often asked is how to properly tune a motor. It has always been considered some form of black magic by those who have not had many opportunities to perform a tuning operation-and a painfully learned technique to those who have.
The development of the Sawyer Planar linear motors, both single axis and xy type, is briefly presented.
The theory of operation is presented for the benefit of those who may be
unfamiliar with these devices. This article presents the basic operating parameters and the characteristics of the devices.
