Eastec Demonstration Walkthru Martin Hardwick David Loffredo STEP-NC Manufacturing Center Watervliet Arsenal, Building 20 Metal Processing Manufacturing Division Watervliet, New York (518) / (518) fax

Slide 2 M. Hardwick 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

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

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

Slide 5 M. Hardwick Header of STEP File testpiece.stp

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

Slide 7 M. Hardwick 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 UGS Compositor AP-238 CC1 Converter on CNC AP-238 CC2 AP-203

Slide 8 M. Hardwick Toolpaths in UGS NX

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

Slide 10 M. Hardwick AP-238 CC1 file added to Compositor

Slide 11 M. Hardwick Siemens codes generated by the converter stage1.mpf

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

Slide 13 M. Hardwick Probe data in Mastercam

Slide 14 M. Hardwick AP-238 CC1 Probe file stage 2.stp

Slide 15 M. Hardwick Probe data in compositor

Slide 16 M. Hardwick Siemens code generated by converter stage2.mpf

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

Slide 18 M. Hardwick 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

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

Slide 20 M. Hardwick 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 Compositor Converter on CNC AP-238 CC1 Operator

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

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

Slide 23 M. Hardwick Mastercam data

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

Slide 25 M. Hardwick CC1 tool path in compositor

Slide 26 M. Hardwick Siemens codes stage5.mpf

Slide 27 M. Hardwick 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 Compositor AP-238 CC2

Slide 28 M. Hardwick Final assembly data in compositor
