Gantry systems, sometimes referred to as Cartesian robots, are ideal positioning systems for automated transfer lines. In this type of manufacturing process, a continuous or indexing conveyor transfers parts from [...]

Many positioning stages used in process applications--such as semiconductor manufacturing, microelectronic assembly, lab automation, and light machining--are characterized by attributes such as light inertial loads, short travel, small footprints, and [...]

Take the covers off such precision equipment as inkjet printers, scribers, and scanning microscopes, and you'll likely find a finely tuned positioning system. It is paramount that the positioning mechanics [...]

Precision-positioning systems used for metrology, inspection, printing, DNA as-saying, and laser machining are typified by a need for smooth motion and constant velocity. For example, a camera uses edge contrast [...]

The physics of positioning systems relate the parameters of motion control components to the overall system performance. While the relationships obey, in general, known kinematics, dynamics, and structural equations, they […]

Siemens and Anorad Corp. join forces to optimize machine-tool performance using high-force linear motors. High-performance linear motors give machine tools exceptionally smooth motion, high accuracy, and high force in all [...]

The installation of linear motors in industrial machinery provides numerous advantages compared to the use of ball screw actuators. Linear motors are composed of two parts while ball screw drives have 17 separate parts. Moreover, tests revealed that linear motors' performance are superior as far as frequency responses, acceleration and deceleration, and velocity times are concerned. These motors are also capable of handling shocks due to hard stops., The new formula for high-performance motion control links lightweight machines with stiff linear motors. Linear motors virtually eliminate backlash, friction, and jitter in systems combining high speed and accuracy. Though [...]

The article discusses the effectiveness of miniature parallel kinematic gantry as a cost-effective option for desktop animation tools. Topics include criteria for selecting miniature kinematic gantries including application requirements for travel, throughput and static precision, and miniature belt-driven ganstries precision dynamic characteristics including accuracy, uni-directional repeatability, and bi-directional repeatability.
