and/or Electrical Runout Inspection
Inspect either mechanical runout or electrical runout, or both
at the same time. We have a wide selection of available probe
ranges and probe types to suit your needs, including LVDT, half-bridge,
inductive, capacitive, fiber optic, and laser probes.
IntelliProbe is a software technology designed to address
problems common with circular geometry inspection, such as profile
distortion due to part misalignment. This "Intelligent Probing"
corrects for part mis-centering errors of up to 1% of the part
radius with negligible error. It also allows for true normal-to-axis
evaluation of surface roundness.
Inspection Templates can be created using AccuScan
IFE, the Inspection File Editor. An Inspection Template
is an inspection program that your can program and save off-line,
and email to your suppliers. A copy of the Inspection File Editor
ships with every AccuScan system.
Inspections are saved as Geometry Data Files. These files are
very small and can be quickly emailed for viewing by anyone
who has the free AccuScan
Result Display Modes
There are four ways that inspection results can be viewed:
Plots - A polar graph of the surface data, which
can be manipulated by the user.
Results - Discrete data for each surface measurement
(e.g. roundness, runout).
- A sample of the surface data as it would be measured
using a manual dial indicator. The number of data points
and the format are configurable.
Charts - Data is plotted in a strip chart fashion.
Preview any of the available
Inspection Reports before printing.
Export any of the available Inspection Reports as a PDF file.
Export or copy/paste the Calculated Results or N-Point format
data grid to a spreadsheet program like Excel.
In Multi-Scan Mode, you can rotate the part through several
revolutions and get a separate result for each rotation.
There are three different modes of inspection:
- The number of points per revolution is programmable, and
the data collection rate is automatically set according
to the rotation speed.
- The number of points per revolutions is programmable,
and data collection is triggered by mean of a proximity
probe. For example, data collection can be triggered by
blade tips in a compressor.
- The number of points per revolution is determined by means
of a rotary encoder. The encoder can be attached to the
inspection machine (as in our stacking
systems), or an Encoder Wheel Assembly can be used (Available
as an option).
Tip Runout Inspection
blade tip runout is a breeze with AccuScan.
Each of the electronic probes can be calibrated independently.
The Probe Calibration Wizard is used to perform this calibration
as needed. There are a variety of calibration options to accomodate
virtually any type of probe.
Probe Calibration Wizard
AccuScan has the ability to measure interrupted surfaces. For
example, a diameter with radial slots cut through it. When an
interrupted surface is measured, it's critical that data in
and local to the interruptions be removed in order to prevent
biasing of the geometry calculations. AccuScan will find these
interruptions automatically (they do not have
to be evenly spaced), and remove data local to each interruption
via an Interrupted Surface Cutoff (ISC) value set by the user.
There is also an "AUTO" setting which can automatically select
an appropriate cutoff value for you.
Part Features as Datum Surfaces
A very powerful feature! You can define a datum coordinate
system using surfaces on the part you are measuring, and then
measure the part using those datum surfaces. There are two
ways to establish the datum coordinate system:
Diameters - the datum axis is a straight line passing through
the best fit centers of the two diameters. The datum plane
is normal to the datum axis.
and a Face - The datum plane is established by the best
fit plane through the face. The datum axis is normal to
the datum plane a passes through the best fit center of
you can measure the part, and then define the datum surfaces
afterwards. All of the inspection data will be properly transformed
into the part datum system automatically.
A user selectable gaussian low pass filter can be configured
for each probe. The selectable cutoff frequencies in undulations
per revolution (upr) are as follows:
0, 15, 50, 150, 500, and 1500 upr
Inspection data are displayed in a convenient table format.
The list of calculated results
may be modified at run-time using the "Options" menu.
The number of significant digits displayed is user selectable.
There are separate settings for the magnitude and angle display.
These settings are available via the "Options Menu".
Each probe can be configured for the type of the surface that
it will be measuring. Proper definition of the surface type
ensures that polarity of the surface data will be considered
correctly (e.g. OD vs. ID).
