ABSTRACT

This presentation will address the challenge of developing, integrating and deploying Check-Mate checkers/profiles into GM Math Data Validation processes.

3

General Motors Validation Facts

Check-Mate as globally agreed upon CAD validation tool

Successfully implemented Check-Mate at all GM Global Sites

Enforced 53 Check-Mate Checkers as part of GM workflow

Check-Mate used as CAD Data Assessment Tool

More than 200,000 NX parts assessed weekly using check-mate batch mode

Significant improvement in Math data quality

Validation Technology

GMNA – DCS File Checker(Mostly File Organization Checks)

GME – SQS/DQS(Mostly Structure / Data Checks)

Retiring different GM custom validation tools at different regional sites

Accepted Solution

Check-Mate as globally agreed upon CAD validation toolChallenge

Advantages

Validation framework that is supported, enhanced and maintained by Siemens

Better error reporting

(tree structure, failed objects, external log files)

Performs Validation on Assemblies/Folders

(Native and Teamcenter)

Check-Mate execution from command line

7

Business Processes

Challenge

Checks Vs. Workflow

Different checks required at different sites for releasing data

Accepted Solution

“Global Quality Seal” Profile consisting 53 globally agreed upon checkers (File Organization and Data Structure Checkers to begin with )

Advantages

CAD Data validated to globally agreed upon GM data creation standards

Smooth data sharing between global sites

Global regions now speak same validation

language

8

Integration with Teamcenter

Enforcement Saving Checking Results (Teamcenter/NX ?)

Teamcenter Groups and Checking Results?

Importing Native CAD Data and Validation Results?Challenge

Accepted Solution and Advantages

Check-Mate results are saved in NX part file and in Teamcenter

Different groups can execute different Profiles and still can be enforced using Tc XML rule file

With Tc 2007.1 validation can be performed from Tc product structure editor

NX 5 now will create validation objects when native data is imported to Tc

Baseline Rule File Item: AKP62495 All WIP Item Revisions validated to same checks

Hard Release Rule File Item: AKP86750 WIP Item Revisions can be validated to different checks based upon Owning Group of Item Revision and Dataset Type

Replicated to the following sites:GMTG_Production, GMPT_Production, GMSA, ISUZU_Production, GMM_Production, GM_Suzuki, Holden_Prod, JCI_Warren, IMC-141231374, Torrance, GMB-S.CAETANO, GMCL-REC_Production, FCA_HF_Production, SaabTDC1, GMPTE, GMDAT, EDAG_GME, Manuf_Production, GM-Strasbourg, GMIDEL_Production (Master in SCG001)

Check-Mate Performance

Challenge

Checking Time + Result Display Time

Check-Mate checking time is on higher side as compared to our legacy NX/Open validation tools

Accepted Solution (Functional and Core Architecture)

Set environment variables that limits display of failed objects in check-mate results window

UGCHECKMATE_MAX_DISPLAY_ENTITIES

UGCHECKMATE_MAX_LOG_ENTITIES

Skip “read-only/released” NX part from checking

Skip part files having check-mate flag PASS and Up-To-Date

Set environment variable that will not bring-up results window when checking is complete UGII_CHECKMATE_AUTO_SHOW_RESULTS
