control interface with YAG and CO2 operating modes
Scanners have been used with servo axes to mark objects that exceed the operating
envelope of the scanner. Applications were previously implemented using a move
and expose sequence where the scanner would mark the part and the servo would
reposition the part for a subsequent marking operation. This approach has limitations
when a feature being marked exceeds the field of view of the scanner. Small
angular and linear offsets in the servo axes produce discontinuities in the
features that cross the boundary between adjacent marking fields. By combining
the servo and scanner control into a single platform, it is now possible to
mark large features by combining continuous motion of the servo axis with simultaneous
marking by the scanner.
Making the Difficult Easy
Direct, coordinated control of scanner and servo axes eliminates the programming
overhead associated with gluing together two separate control systems, resulting
in reduced implementation time and increased marking efficiency. Scanner motion
can be combined with rotary axis motion to mark on the face or edge of cylindrical
profiles. Rectangular bitmaps that exceed the scanner field of view width can
be marked in one continuous operation. Complex operations comprised of many
small features distributed across a large area can be marked in a continuous
fashion with a significant reduction in processing time.
Full Featured I/O
Nmark™ SSaM has support for CO2 and YAG lasers with specialized functions
such as first-pulse suppression and tickle frequency outputs. Control signals
can be configured as sinking or sourcing, 5-24 VDC, allowing for easy interface
to many different laser manufacturers. General purpose analog and digital I/O
is also provided for control or monitoring functions such as laser power, door
interlocks, pump operation, and material handling. Two high-speed encoder inputs
are available for synchronization with moving material applications (marking
on the fly).
