HXP100P-MECA & HXP100PHA-MECA 6-Axis-Parallel Kine atic Positioning Syste s
2.0 —Description
The HX 100 -MECA 6-Axis Hexapod is a parallel kinematic motion device
that provides six degrees of freedom: X, Y, Z, pitch, roll, and yaw. The
HX 100 has long travel capability and is an effective solution to complex
motion applications that demand accuracy in up to six independent axes.
Contrary to the image of being complex and highly priced, the
HX 100 -MECA hexapod is not only affordable but extremely easy to use.
The HX 100 -MECA design also includes two programmable pivot points,
enabling more flexibility to align a sample at a particular point or points of
that sample. The HX 100 -MECA Series also takes advantage of the
Right ath™ trajectory capability, enabling scanning in a path along a
defined trajectory, line, arc or rotation, at a constant and definable speed
with low-runout.
Derived from the HX 50-MECA, the HX 100 -MECA is driven by six DC
servo motor actuators with encoder feedback at the leadscrew nut,
providing precise MIM, low backlash and fast speed. The quality of the
actuators has obviously a strong impact on the overall motion
performance of the HX 100 -MECA, but of equal importance are the joints
with which the actuators are attached to the base and the moving top
plate. With size and rigidity in mind, our engineers came up with
innovative spherical joints that are not only very simple, but also enhance
the stiffness of the hexapod.
To further ensure positioning performance, the High Accuracy (HA)
HX 100 HA-MECA is available with guaranteed accuracy values. This
enables the use of a Newport Hexapod in positioning applications, where
position accuracy is required. In addition to accuracy along an axis, the
itch and Yaw deviations during axial motion are also monitored and
guaranteed. When the HA Hexapod is used with Right ath™, this
combination achieves positioning performance close to standard Newport
stages.
The HX 100 -ELEC and HX 100 HA-ELEC provide advanced features
including instrument grade I/O's, hardware based input triggers, event
triggers, high-speed on-the-fly data acquisition, fast TC /I
communication, and integrated TCL programming language for on-board
processes. All these features improve accuracy and throughput, making
the programmer’s life much easier. Order the hexapod with the
corresponding controller.
A common requirement for many Hexapod motion applications is a virtual
pivot point, allowing the user to freely choose the point in space that is a
pivot point for all rotations. The Newport Hexapod can not only relocate
the pivot point, but through our advanced technology, the entire
coordinate system can be relocated. In addition, two user-definable
coordinate systems are provided, called tool (moves with the Hexapod)
and work (stationary coordinate systems). Incremental displacements are
possible in either one of these systems in user-friendly Cartesian
coordinates, and positions can be easily calculated from one system to the
other by a function call, without the need for complex external coordinate
transformations.
