The AGS1500 series Cartesian gantry is the compact version
of our AGS15000 gantry, and is designed for ultra-precision, high-dynamic
contouring. The planar design minimizes dynamic pitch errors at the work point.
AGS1500 systems are used in precision micromachining, stencil cutting, fuel
cell manufacturing, solder-ball placement, printed electronics, high-speed
pick-and-place, automated assembly, vision inspection, dispensing stations, and
high-accuracy inspection where space is at a premium and high accuracy and
speed is essential. Brushless linear servomotors drive the AGS1500 to speeds of
3 m/s and accelerations of 5g, with travels up to 500 x 500 mm and resolution
of 1 nm. The AGS1500 provides design engineers with a gantry specifically
designed for high-dynamic, precise contouring applications in space-constrained
environments, significantly improving process accuracy and throughput.
Customizable Z and theta axes allow the flexibility to create the exact
configuration they require and that is most efficient for their process. The
AGS1500 also was designed with the linear motors and encoders on the outside of
the work area, resulting in a reduction in downtime due to debris-induced
damage. And finally, the configurable cable management system allows design
engineers to easily integrate lasers, cameras, air lines, and other elements
for a truly optimized system. Compared
to other designs where the bridge is mounted above the bottom axis carriages,
the AGS1500 utilizes a planar design where the cross-axis is in line with the
bottom axis motors. This greatly reduces the errors due to pitch of bottom
axis, improves the stiffness, and extends the servo bandwidth. With high
stiffness and servo bandwidth, the dynamic tracking performance greatly exceeds
that of other designs. In addition, both the magnet tracks and the encoders for
the bottom axis are mounted to the outside of the gantry for protection during
material processing - i.e., laser processing can generate debris.
A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
