2 Agenda 1 Introduction Laboratory for Computer Integrated Design and Manufacturing Learning Environment Conclusion Figura 2

3 Motivation Source: Learning Factory Morphology Application. Figura 3

4 Motivation CIRP Learning Factory Morphology Application Production (product process, manufacturing, assembly): environments Production Digital Factory: 2 20 environments Logistics 20 environments Energy Efficiency 20 environments Source: Abele, Opening Speech Design Process 15 environments Design: 1 environment Product Development: 1 environment Learning Factories not include in CIRP Morphology: focus in production/assembly Product Development Process is critical activity in the Production Lifecycle Management Implementation of an Industrial Product Engineering Scenario PLM, CAD, CAM, CAE Figura 4

5 Motivation Undergraduate students: Development of product development process skills Professionals: Continuous learning in new digital product development tools Learning environment to support the product development process Focus: process and digital tools (PLM, CAD, CAM, CAE) Lack of Learning Factories with focus in the Product Development Process and its digital tools Bring industrial environment and requirements to the university Figura 5

6 Agenda 1 Introduction Laboratory for Computer Integrated Design and Manufacturing Learning Environment Conclusion Figura 6

7 Laboratory for Computer Integrated Design and Manufacturing - SCPM The Learning Factory for Product Development Process was developed and implemented by the Laboratory for Computer Integrated Design and Manufacturing (SCPM) of the Methodist University of Piracicaba (UNIMEP) Figura 7

8 Laboratory for Computer Integrated Design and Manufacturing - SCPM Human resource: Full Professor, PhD. students, master students, undergraduate students and technical support staff (secretary and system analist) Partnerships with other universities and industries More than 20 years Figura 8

9 Agenda 1 Introduction Laboratory for Computer Integrated Design and Manufacturing Learning Environment Conclusion Figura 9

10 Learning Environment - Objectives Learning environment on product development process Simulate a real design process of a new product Development of product variants with common and different components Support of product change requests by production and after sales Learning environment for undergraduate and graduate study programs and professionals Combine theoretical and practical learning Figura 10

11 Learning Environment - Resources Product development scenario similar to the industries Human resource: Undergraduate and graduate classes of the engineering courses Professionals from the industry Hardware resources: Workstations, servers with a client-server infrastructure Systems resources: Teamcenter NX Microsoft Office Package Figura 11

12 Learning Environment Design Team Supervisor Designers Figura 12

13 Product Development Process The training at the learning factory testbed is divided into seven modules: Module 1 System introduction Module 2 Parts design Module 3 Parts approval Module 4 Version management Module 5 Assembly Module 6 New product Module 7 Enterprise change request Figura 13

14 Design teams The implemented scenario 30 students divided into 6 Design Teams Each of these teams is composed of 5 students 1 supervisor and 4 designers Figura 14

15 Design Team Supervisor Manage the product development cycle Built design team Modeling, simulations, drawings Product definition and requirements 2 Product versions with common and different components Workflow definition Designers Receive tasks through PDM workflows Design, simulation and drawing requested components, assemblies and final product Send designed components for reviewing Execute necessary modifications Task distribution through PDM and selected workflows Review and release of designed parts, assemblies and final product Figura 15

16 Product Description Crosshead axis 3 subsets 11 different components Subset_2 Subset_1 Complete_set Subset_3 Figura 16

17 Product Description Bottom-up construction process The construction of each component is using Siemens NX CAD Figura 17

18 Product Description Product 1 Subset 1 is designed considering that the shaft-hub joints are made by interference Product 2: Subset 1 is designed considering that the shaft-hub joints are made by cotter At least one imported part (delivered by supplier) Part_12 New component Part_05_new Modified component Part_04 Part_03 Part_01_new Imported component Part_02_new Modified component Figura 18

19 Product Development Process Management 4 workflows were created for different use situations Component design Component import (parts from suppliers) Assembly/Simulation the subset and final product Creation of the technical drawings for process planning Basic sequence Figura 19

20 Bill of Materials - BOM Comprises the components and the product structure Contributes to departmental integration The information is shared with the departments involved in the process Figura 20

21 Product Browser Figura 21

22 Change request Objectives: Significance of the required modification Impact of the modification Impacted products, assemblies, parts Item modification X new item Relation between components and subsets JT preview to analyze if the modified component influences another component In the Learning Factory, this activity was implemented considering a modification requested by the manufacturing supervisor Figura 22

23 Change Request Modifications or improvements are proposed and implemented through an Enterprise Change Request (ECR) Figura 23

24 Impact Analysis Verify the inter-relationships of the component and subset between the two constructed products Impact analysis function Helps the designer to identify whether a component that will be modified belongs to more than one product and how the requested changes could impact Figura 24

25 Agenda 1 Introduction Laboratory for Computer Integrated Design and Manufacturing Learning Environment Conclusion Figura 25

26 Conclusion There are several learning factories over the world; the main focus is in the production This testbed is a product development environment, where students are presented to the challenges of modeling a product The implemented Scenario proved to be able to represent real processes and problems of the product development cycle Not all universities have such a modern structure, so UNIMEP graduates stand out when introduced to the labor market Figura 26
