Design |
|
All standard systems, and most custom systems, are
designed around a tubular steel weldment for support of the optical
beam delivery, motion stages, power distribution, and possibly even
the laser depending on the particular system. These frames are
robust, economical, and quickly modified as necessary for each
customer's unique requirements. Optical components are
procured from suppliers with a proven track record in quality optics
and robust, damage-resistant coatings. |
 |
|
Electrical build standards comply with
NFPA79. All systems include Emergency Stop and safety
interlock circuitry.

Controls
 |
|
For most systems, the
operator interface to the sophisticated motion control is through a PC
running a Windows® environment. Operator access is limited to the
basic commands required to load and run a pre-set job. Administrator
access is password protected and allows creation of job files as well as
service and calibration settings. Since the controller keeps track
of both location and shot count, if a program is interrupted for
some reason, the controller is capable of resuming from the exact
location required. This minimizes the need to re-process parts
or otherwise scrap a partially finished part.
Optional equipment includes an integrated vision system for
alignment to fiducial marks on the part (e.g. PWB or flex panel) and
hardware for automatic load/unload of parts, also fully integrated
into the control. |

Documentation |
|
Documentation of the system usually
comprises an Installation Manual, an Operator's Manual, and a
Service Manual. Safety aspects are always highlighted early in
the manual. Routine maintenance is covered in the Service
Manual, and all special tools required (e.g. Allen keys for removal
of latched panels) are included in the Service Kit that accompanies
all systems.

|
System Test |
|
All systems are thoroughly tested for
full functionality prior to shipment, and again after on-site
installation. Normally there is a process acceptance test as
well, to prove out all critical features of the system and the
process, involving comparison with previously-generated 'witness' or
'benchmark' samples. Customers are encouraged to attend and
participate in the factory acceptance testing to ensure the process
results meet with their approval.

Training |
|
With the on-site commissioning of each system,
training will be conducted for personnel with operator, supervisory
access and maintenance responsibilities. Topics typically
