Constructionn,CAD and CAM

This section is divided into two main areas: the education of engineering  and CAD.

In CAD research there are several actual projects at the moment. We are working in the area of offline programming to create and optimize robot supported processes and sequences. The aim is to reduce the overall process time by reordering the several sub-processes in  an appropriate way. Furthermore it can be determined if a process can be realized at all. For this work CATIA V5 and Delmia V5 are used.
 

 

 

The other area this section is working on is to create robot tracks automatically. For Example mountings. The IFB developed a software that is able to create mountings with arbitrary inner our outer geometry.

In this case the recognition of structures and shapes of parts is very important. The parts that have been scanned with a 3D Scanner can be transformed into their original mathematical shape via a surface reconstruction so that it can be edited in any current CAD program.

 

In the first semesters of the Bachelor program the engineering education plays an important role. There are lectures for the basics of engineering  the teach the student the construction of machine parts. In semester three the students have to attend construction seminar where they have to apply there learned skills in a semester exercise.

Projects:

The FlexiCut Project:

Within the FlexiCut project a pilot installation of a robot cell will be realized to prove that composite part can be edited more cost-efficient with more units and a constant quality. For that the newest technologies in clamping, part editing, robot control, process simulation an quality management will be combined. The aims of FlexiCut are listed in the list below.

  • Reduction of process time for one part cycle of about 50%
  • Reduction of energy consumption of 20% (according to the whole energy balance of the process)
  • Reduction of resource usage of 40%
  • Increase of robot accuracy of 40%


The work package of the IFB in this project is the development of a special Software(FlexiCAM) that can create robot programs for any special application with the help of a knowledge Base. Furthermore the user should be able the create his one machines and do some CAD work in within the program.


runtime of the project: until October 2013

 

The CANAL Project

The EU-project CANAL (CreAting NonconventionAl Laminates) is based on the project AUTOW (AUtomated Preform Fabrication by Dry TOW Placement).

Within the scope of CANAL, new Non-Conventional composite laminate configurations using DFP (Dry Fibre Placement) in combination with LCM (Liquid Composite Moulding) will be developed. Further, engineering tools for the design of efficient structures made of these new configurations shall be established.

The project integrates laminate design, manufacturing and structural design to ensure the industrial applicability of the technology in the aerospace industry and other industries, such as automotive, that can benefit from rapid and cost effective production of complex shaped and high-performance composite parts.

The IFB Work package consists of the following items:     

  • Implementation of industrial design guidelines using existing software, an existing data base and an online loop to Coriolis
  • Automatic fibre path generation and validation of FlexiCAM results
  • Case studies and software benchmark

 

Project starts October 2013
