Comparing the Machined Stock Part and the Design Part


  Stock Analysis is only available if you have an NC Manufacturing Verification product license.

This procedure describes how to compare the machined stock and the target (design) part by using the graphical comparison functionality.

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

This functionality 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.

Click Stock Analysis in either the Process Simulation toolbar (while the simulation is paused) or on the Stock Management toolbar, when no simulation is in process.
  1. In the Analysis dialog box, click Analyze .

     The Analysis dialog box appears.
    The default appearance of the Remaining Material tab gives three tolerance bands for analysis. Click the More button to access additional tolerance bands.

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

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

  3. Click Apply.

    The machined part is compared with 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.
    Results of the comparison are reflected on the workpiece, based on the extent of severity of the fault and the customized color settings.
