Aerotech's Harmonic Cancellation algorithm dramatically reduces positioning errors on systems with periodic trajectory commands or disturbances. This feature, part of the Dynamic Controls Toolbox, provides an easy-to-use command set and graphical user interface to enable the algorithm and to extract the highest possible performance from your investment in a precision motion control system. For more information, read the Motion System Design magazine article, Harmonic Cancellation Algorithms.
Aerotech's Position Synchronized Output (PSO) feature coordinates your motion subsystem with laser firing to produce the highest quality parts and minimize cycle time.
Fully configurable to interface with lasers equipped with externally synchronized control, including CO2, YAG and excimer fiber lasers.
PSO functionality includes several easily programmed operation modes.
When using a fixed frequency laser, this is complicated by the need for constant velocity, severely limiting processing speeds when faced with complicated geometries. Aerotech's PSO solves this problem.
Use to Trigger
Nondestructive test triggering
Turbine blade holes
Fuel injector drilling
PSO fire points are defined in an array based on calibrated position
Pulse train specified with absolute positions
Variable pulse width
Specify pulse lead, pulse and pulse tail for precise energy delivery
Output pulses are constrained inside a user-defined window with the first pulse relative to the edge of the window
Excellent for when the processing of a part requires the axes to move beyond the part for settling or direction reversal in applications such as flat-panel manufacturing or fuel injector drilling
Fixed Distance Firing
Single- or multiple-pulse output as a function of up to 3 axes' position feedback
Minimizes heat-affected zone in welding, cutting and drilling
Outstanding for stent manufacturing, hermetic welding and drilling holes in turbine blades
Expand scanner field of view without sacrificing effective pixel resolution
Mark long vectors with one continuous pass
Draw large-scale graphics without stitching multiple exposures
Mark on a tube or other irregularly shaped object without manually repositioning
Industry standard XY2-100 interface supports scanners from multiple vendors
Single programming environment for both scanner and servo axes minimizes application complexity
Eliminate angular errors
Scanner programmed with standard RS-274 G-Code
By combining a single linear servo axis with a scanner, the Nmark SSaM BroadMark function makes it possible to mark graphics over the entire travel of the linear stage in one continuous operation. This approach removes overlay errors that occur when the image is created through a series of adjacent bitmaps.
