Comparing Machined Stock Part and Design Part

You can compare the machined stock part and the target (design) part by using the video analysis in NC Manufacturing Verification.


  • Areas on the machined stock from which extra material has been removed are reported as gouge.
  • Areas where material has not been removed completely are reported as remaining material.

The video analysis in NC Manufacturing Verification provides a visual comparison achieved by color-coding the stock according to how close the machined surface is to the surface of the target (design) part:

  • A series of tolerance bands and a color for each band is defined.
  • All points on the machined surface that lie within a particular band are given the corresponding band color.
  • By defining the tolerance band appropriately, all remaining material points or gouge points on the machined surface can be identified and displayed in as many colors.
  • The magnitude of remaining material or gouge can also be queried at a specified point. This magnitude is the shortest distance between the picked point on the stock and the nearest point on the target (design) part. The coordinates of the picked point on the stock are also displayed along with the magnitude of remaining material or gouge.

Customizing options are available. See Photo/Video and Simulation.

  1. Select a Machining Operation in the Manufacturing Program, then select Tool Path Replay . See Replaying the Tool Path and Simulating Material Removal in Video Mode for general information.

  2. In the Tool Path Replay dialog box, click Full Video to simulate the material removal by the Machining Operation.

    The material removal video appears in a new window.

  3. Start the comparison:

    1. Click Analyze .

      The Analysis dialog box appears.

      By default, the Remaining Material tab displays three tolerance bands for analysis. More gives access to additional tolerance bands.

    2. Select the Automatic refresh after view change check box to refresh the window after a view change.
    3. Select the check box associated with the fault type to be analyzed (Remaining Material or Gouge or both).
    4. Go to the corresponding tab and specify the tolerance bands for the comparison.

      The remaining material and gouges are displayed as colored zones according to the specified tolerances.





    5. Click Apply.

    The machined part is compared with the design part, based on the specified settings.

    • Any point on the machined surface of the workpiece is considered to be part of a fault if the distance (deviation) to the design part surface is greater than the specified tolerance.
    • The results of the comparison are reflected on the workpiece, based on the extent of severity of the fault and the customized color settings.


  4. Still in video mode, pick a point on the machined stock.

    The Pick Point Information dialog box appears.



    Notes:

    • This information is available at every pick, provided that the point picked is a "machined area pick".
    • Arc radius and Arc center are populated only if the picked point is on a circular entity.
    • Deviation is displayed after you have compared the machined stock part and the target (design) part : the stock is rendered in a color-coded manner, depicting deviations from the design part. A subsequent pick displays the deviation value.

    Important: When the design part is a surface entity with no thickness, the deviation on one of the sides is accurate and the deviation on the other side of the surface may be incorrect and may show infinity.
