Geomet
provides several Digitizing and Scanning
modes for use in reverse engineering. These
modes expand your CMM beyond the traditional
inspection platform into a support tool to
redefine and explore production parts that
may have no known nominal data.
Additional uses include defining outline
shapes to determine CNC path generation. All
data can be exported in IGES format as
complete entities, or as XYZ data point
locations in DXF and ASCII formats.
Geomet 501 provides support for analog
contact scanning utilizing probe systems
such as the Renishaw SP25. This method
provides high concentration of data points
for better feature analysis and reverse
engineering.
Manual Digitizing:
MANUAL DIGITIZING is basically performed two
ways. Taking single points with a touch
probe is most common for lower point
densities. to capture large data clouds,
GeoTracer or drag-digitizing in Geomet where
a solid probe is "dragged" across the
surface, provides a stream of data points at
predetermined intervals. This is, by far,
the fastest way to digitize, except for the
Line Laser on a DCC CMM. The data clouds
then can be exported via IGES, DXF or ASCII.
DCC Digitizing and
Scanning:
Digitizing with Geomet on a
DCC style CMM with a touch probe provides several tools
designed to work with many part shapes.
These tools are 2D and 3D to match the
requirement of the end result. The various
tools provide contour walking, which can be
used to capture date on a uneven surface
such as a turbine blade, or even a radial
surface following mode that will capture
data on the end of a cylinder as shown at
the right.
Digitizing with a manual
CMM is provided with tools such as GeoTracer
which provides hard probe drag scanning for
high density data point clouds.
Scanning capabilities are
provided using Geomet 501 and the Renishaw
UCC2 controller. Utilizing the SP25 scanning
probe, you can capture uniform data point
clouds over a variety of surfaces.
Additionally, the scanning capabilities are
applied to prismatic features for a better
understanding of the shape using the
analytical tools built within Geomet.

Line Laser Scanning. This tool is designed
to capture large data clouds which is then
exported and compared to nominal data within
a CAD system.
