Analysis of Generated Parts
The two parts produced using the NC milling machine were
designed to be used on an autonomous robot. The robot is to be used in
a jousting competition with other robots from the University of Maryland.
The top and bottom plates, of the lance turret, were selected for production.
To provide an opening, in order for the 0.1875 plexiglass vertical surfaces
to be inserted, the plates have 0.1875 inch grooves, which comprise the
vertical structure of the turret. The top plate (Figure 2) has an interruption
on either side of the centerline. This will allow a 0.1875 through hole
to be drilled in the plexiglass, normal to the grooves. These small holes
will provide a mounting surface for other components. It will also help
to decrease the polar moment of inertia. The bottom plate (Figure 3) has
more holes to provide mounting options for servo motors and other components.
The plate also has a 0.5 inch counter bore to accept a flanged ball bearing
and a 0.25 inch through hole for the turret drive shaft. These parts were
generated using CADKEY. Subsequent ÒGÓ codes were produced
using Cutting Edge software. The codes were then transferred to the NC
milling machine to cut the parts.
Conclusion
In conclusion, it is the integration of the CAD/CAM system
that allows the manufacturing industry to produce a better product, in
less time, with a lower overall production cost. This technology enables
companies to rapidly introduce new products in an ever changing global
market. CAD/CAM integration allows businesses to meet customer needs more
efficiently and timely.
