  1. Eastec DemonstrationWalkthru Martin Hardwick David Loffredo info@steptools.com STEP-NC Manufacturing Center Watervliet Arsenal, Building 20 Metal Processing Manufacturing Division Watervliet, New York 12189 (518) 687-2848 / (518) 687-4420 fax http://www.steptools.com

  2. Eastec demonstration walkthru • Stage 0 • Export Part model from UGS NX • Stage 1 • Roughing operation from UGS NX • Stage 2 • Probing operation from Mastercam • Stage 3 • Probing results from DMG • Stage 4 • CNC Tool diameter compensation • Stage 5 • Finish operation from Mastercam

  3. Stage 0 – Export part model • Export model as STEP AP-203 CAD file • Read model into compositor AP-203 testpiece.stp AP-203 UGS Compositor Compose data for CNC

  4. Model in UGS (Pratt and Whitney test part)

  5. Header of STEP File testpiece.stp

  6. STEP File in compositor We are going to machine this boss

  7. Stage 1 – Export Roughing operation • Tool paths in UGS NX • AP-238 CC1 file containing the tool paths • AP-238 CC1 added to AP-203 in Compositor • AP-238 CC2 sent to the Converter for machining AP-203 AP-238 CC1 AP-238 CC2 Converter on CNC UGS Compositor

  8. Toolpaths in UGS NX

  9. Header of AP-238 CC1 STEP File stage 1.stp

  10. AP-238 CC1 file added to Compositor

  11. Siemens codes generated by the converter stage1.mpf

  12. Stage 2 – Export probing operation • Probing operation in Mastercam • AP-238 CC1 file exported from Mastercam • AP-238 CC1 file in Compositor • Siemens codes AP-203 AP-238 CC1 AP-238 CC2 Converter on CNC Mastercam Compositor

  13. Probe data in Mastercam

  14. AP-238 CC1 Probe file stage 2.stp

  15. Probe data in compositor

  16. Siemens code generated by converter stage2.mpf

  17. Stage 3 – Read probe results into compositor • Probe results as produced on DMG machine • Probe results merged into the AP-238 CC2 file AP-238 CC2 AP-238 CC2 Converter on CNC Compositor probelog.txt

  18. Probe results produced on the DMG probelog.txt • DMG machine uses metric units • Pratt and Whitney test part uses inches • Converter converts between the units

  19. AP-238 CC1 probe results stage 3.stp • In “stage 2.stp” entity 177 has a NULL initial value

  20. Stage 4 • Set value of compensation register • We could decide this in a CAM and send new toolpaths • We could decide this in the converter using a STEP-NC expression • Instead we let the operator set the value using a window in the compositor • Value sent as a STEP-NC register assignment Operator AP-238 CC1 Converter on CNC Compositor

  21. AP-238 CC1 file sent to the converter stage 4.stp

  22. Stage 5 – Final finish using compensation • Mastercam with cutter compensation • AP-238 CC1 data with cutter compensation • Siemens codes generated by converter AP-238 CC1 AP-238 CC1 Converter on CNC Mastercam Compositor

  23. Mastercam data

  24. AP-238 CC1 file with cutter compensation stage 5.stp • Surface normal describes left or right

  25. CC1 tool path in compositor

  26. Siemens codes stage5.mpf

  27. Final assembly • We can assemble a STEP file to record all the operations executed on the machine • UGS NX data for the roughing • Mastercam data for the probing • DMG probe results • Cutter compensation assignment • Mastercam data for the final finish AP-238 CC2 Compositor

  28. Final assembly data in compositor

  29. AP-238 CC2 data for final assembly final assembly.stp
