Our engineers have a broad background in machine
design, and have been helping clients achieve their design
goals since 1996.
We are fully equipped with the latest CAD and analysis
packages. Your system will be fully modeled before it is
ever built, using detailed solid models. You can regularly
review progress via 2D prints or fully rendered 3D layouts.
In addition, we can provide you with fully rendered views
for presentation to your customers.
Sample
machine design projects:
Automated Tube
Grinder
The Client:
This client is a local Seattle
aerospace company.
The Task:
Provide the client with machine
design, electrical schematics, programming, documentation,
and training for an automated tube grinder. The
Tubegrinder was built by a local area shop.
System
Description:
The tube grinder is used to
simultaneously grind a shallow chamfer on the ID and OD of
2" and 3" diameter carbon fiber composite tubes. The angles
must be ground to a repeatability of 0.02° from part to
part. The air motor driven grinding wheels are diamond grit
plated. The linear and angular positioning of the two
grinding wheels are controlled by four servos. The unit is
controlled from a menu driven handheld pendant. The operator
can select from a pre-defined list of grind setups. The feed
and speed of the tube, and the rotational speed of the
grinding wheels are all controllable. There is a
positionable vacuum system that takes up the dust. The unit
is enclosed in a Plexiglas cover on gas springs. An
Opto
22 programmable controller
runs the process; controlling all the servo motors and air
driven devices. The operator can, from a menu on the
handheld terminal, adjust the position of a ground surface
within its drawing tolerance zone. The unit has been in
operation since 2000.
