  • Sphere Scanning(?)

    Is it possible to scan ( with a sp-25 ) a sphere. I can not find anything that I can choose that will let me scan one. I want to check all my probes in one program with a quick qual check program. I can do normal spheres with the auto/sphere but they won't scan the sphere. Any suggestions.

    Never tried it, but I believe a patch scan should work.

      Been there, done that. . . .

      I've done this with the Freeform scan function. You need only to supply the path data in the form of a text file. I've done spirals most of the time, but the path is only limited by your imagination. You can create the path files using a BASIC script, or even from an Excel spreadhseet.

        BASIC SCRIPT? EXCEL? WHAT? HOW? Would you happen to have a snap shot of what you are describing? Do you program on-line or off-line to create these scans?

          Spreadsheet Export Example

          Here is one example. This is a spreadsheet that can be used to generate scan points and vectors for a sphere of any size.

          Change the A2 cell to show your sphere size, then when you exit that field it will fill in the remaining cells with hit/vector data.

          Export this sheet to a CSV file (SaveAs). Depending on how you do this, you may need to edit the file to remove excess fields and characters. In the end, it should look like this -

          -8.118533,-4.981471,0.000000,-0.852339,-0.522989,0.000000
          -8.063418,-5.070199,0.000000,-0.846553,-0.532304,0.000000
          -8.007330,-5.158323,0.000000,-0.840665,-0.541556,0.000000
          -7.950279,-5.245826,0.000000,-0.834675,-0.550743,0.000000
          -7.892275,-5.332694,0.000000,-0.828585,-0.559863,0.000000
          -7.833322,-5.418920,0.000000,-0.822396,-0.568915,0.000000

          for as many points as you want to include. This file format DOES NOT USE the XYZIJK file header that is used in other areas of PC-DMIS. All records are identical format.

          Now, in your part program, Insert - Scan - FreeForm, go to the Path Definition tab in the dialog, and then hit the ReadFile button. Use the browser to find the data file you just created, Once selected, you should see the data points in the scan dialog path window. Hit Create, and it stores it into the part program.

              No Spreadsheet. I would be interested in getting a copy.

                I have scanned a sphere. It is a bit messy though. I created two circle scans at 90° from eachother and then constructed a sphere from the data collected.

                If there is a better way I would also love to know!
