- 33 sites generate JT data in TcEng

- Over 150,000 translation attempts / month

- Over 99% JT availability measured

against current product models


PLM Vision

“Make it Visual”• BOM & design data are managed in one integrated

solution

• Design process artifacts are change controlled & integrated to the BOM, forming a Bill of Information

• Visual reporting facilitates improved decision making

• Collaboration across extended enterprise is supported with appropriate information access

• Design geometry is easily shared across the extended enterprise (including suppliers)

“Make Value Flow”• Downstream flow of product & process data

enables success of Manufacturing and Product Support

• Sales & marketing strategy linked to product BOI

• JT represents the geometry master & is the common currency for downstream processes

Virtual Reviews, Audits & Builds

What is a Virtual Event?

Virtual Reviews

3D visualisation software used to:

Conduct & improve configuration concept studies

Identify geometry/process/supplier related issues

Facilitate CPPD discussions during product, system, and component design activities

Virtual Audits

3D visualisation software in conjunction with external SME’s, used to:

Conduct structured design reviews focused toward area of expertise, e.g.

Manufacturing

Service

Safety

Virtual Builds

3D visualisation software used to:

Validate/ simulate real-world build conditions prior to Iron build

Assemble-ability

VFM: Post Validation after JT Import


• Most Business Units run “BVR Validate” weekly, some run it daily

• Checks 25 conditions while validating JT data (date modified, feature ID,

JT/Pro/E BOM, etc..)

– % Total JT

• Total # of BOM lines with a JT file divided by Total # of BOM lines

– % Complete for Engineering Use Case

• Total BOM lines meeting Engineering criteria divided by Total # of BOM lines

– % Usable & Up-to-Date Use Case

• Total usable parts in usable assemblies divided by total parts in the top level

JT Model Validation

% JT Total

• Simply evaluates whether a JT file exist for each unique BOM item

(Yes or No)



JT Model Validation

% JT Complete

• Evaluates whether each JT file meets established criteria for JT file

quality



JT Model Validation

% JT Usable

• Evaluates the impact on the down-stream usability of the JT model

• Dependant on the failed item position & number of children within the

product structure

Summary:

• Caterpillar’s current JT validation processes are

primarily focused on translation success and

completeness of the JT BOM

• Successfully translated JT files have been

geometrically accurate enough for our primary design

review, assembly planning & product support use cases

• New use cases for NC Programming, Machine Shop

Process Planning & Supplier Collaboration will require

validation of B-Rep and PMI accuracy
