Mechanical 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™ Technology
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
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.
Geometry Data Files
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 Viewer.

Multiple Result Display Modes
There are four ways that inspection results can be viewed:

  Profile Plots - A polar graph of the surface data, which can be manipulated by the user.
  Calculated Results - Discrete data for each surface measurement (e.g. roundness, runout).
  N-Point Format - 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.
  Strip Charts - Data is plotted in a strip chart fashion.

Print Preview
Preview any of the available Inspection Reports before printing.
PDF Export
Export any of the available Inspection Reports as a PDF file.
Spreadsheet Export
Export or copy/paste the Calculated Results or N-Point format data grid to a spreadsheet program like Excel.
Multi-Scan Mode
In Multi-Scan Mode, you can rotate the part through several revolutions and get a separate result for each rotation.

Multiple Inspection Modes
There are three different modes of inspection:

  • Timed - The number of points per revolution is programmable, and the data collection rate is automatically set according to the rotation speed.
  • Triggered - 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.
  • Encoded - 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).

Blade Tip Runout Inspection
Inspecting blade tip runout is a breeze with AccuScan.

Probe Calibration Wizard
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.

Measure Interrupted Surfaces
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.

Use 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:

Two 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.

A Diameter 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 the diameter.

Alternatively, 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.

Probe Filtering
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: 

fc = 0, 15, 50, 150, 500, and 1500 upr

Discrete Statistical Results
Inspection data are displayed in a convenient table format. The list of calculated results may be modified at run-time using the "Options" menu.

User-Selectable Significant Digits
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".
Multiple Probe Definitions
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).
