Minutes of Conference Call on 3/17 ---------------------------------- The main part of the discussion was on the CLM demonstration for Eastec. The preferred scenario is as follows: 1. AP-238 CC1 data containing probing operations is written by the CAM and read by the CNC. 2. The CNC converter runs the AP-238 program and records the results of the probing operations in the AP-238 CC1 file. 3. A CAM process reads the modified AP-238 file and uses the probe results to compute additional toolpaths that must be run on the control to make the part more accurate. For example, we could machine a turbine blade part, put some sticky tape on the result, measure the tape and remove it in a second round of machining. The main obstacle to implementing this scenario is that the algorithms to compute how to remove the additional volume have been developed by end users, not the CAD/CAM vendors, so we will need their help to implement a demonstration. A secondary obstacle is that new processes must be implemented to read the modified AP-238 into the CAD/CAM application that computes the modified toolpaths. However, it was noted that provided the reading system fully understands the context of the data, a shortcut can be used where a data mining program is applied to the data to find the probing results. Action items were assigned to see if the resources required can be assembled in time for the demonstration. If not then the second option is to give a CC1 demonstration of turbine blade machining. UGS volunteered to create a turbine blade model as an AP-238 CC1 file for machining from an AP-203 file. If there is time it may be possible to enhance the turbine blade demonstration with CC1 spline data exchange. A workpiece setup demonstration was deemed to be more appropriate for an automotive audience. We may implement this scenario at a follow-on demonstration to be given at AIAG in August. Action Items ------------ * Sid Venkatesh to contact Pratt and Whitney about using their application in the CLM scenario. * Fred Proctor to revise scenario document to include the closed loop machining scenario. * Fred Proctor to find an AP-203 turbine blade design (or similar) * Fred Proctor to update the NIST web page to include the Eastec and AIAG demonstrations * David Odendahl to AP-238 run probing tests * Martin Hardwick to contact Defense Manufacturing to arrange a fourth demonstration at the end of the year. The next telcon will be at 2PM on Thursday March 31st. As recorded by Martin Hardwick on February 17, 2005.
