Practical Trainings
The CAD/CAM lab is used for the following practical trainings:
- Basics of CAD
- Advanced CAx
The participation in Basics of CAD is compulsory for all students. Here they learn the basic 3D work techniques required for using a CAD system. The training is performed in groups at 18 computers.
The Advanced CAx practical course uses practical examples to illustrate the complete process chain of product creation (CAD, finite element method, topology optimisation, reverse engineering and CAM).
Rapid Prototyping
A 3D HP printer (Design Jet Color 3D) has been part of the lab's equipment since October 2012. Rapid prototyping is an additive manufacturing technology that creates objects of ABS polymers through a sequential layering process. The generated "physical prototypes" are useful to assess the object's geometry and help select the right milling strategy for complex milling operations.
Machine Simulation
The CAD/CAM lab is provided with two 5-axis milling machines, which are used for practical trainings. Digital machine models of both machines are available and used for simulating the entire milling process before it runs on one of the real milling machines. Thus the feasibility, the functional and process reliability of the milling programs can be tested.
Manufacturing
The CAD/CAM lab is equipped with a 5-axis Datron milling machine (M8) for high-speed machining (HSM) of aluminium and plastic components which are manufactured in the CAD/CAM practical training. The HSM uses speeds up to 50.000 1/min and movement speeds and feeds up to 20 m/min. A minimum quantity lubrication is applied for the milling of aluminium components.
The DMG machining center (DMG 50 eVo linear) is used for larger components and other materials and supports, for example, 5-axis simultaneous machining. It is located in the workshop building.
Both machines have postprocessors, which compile the machine-independently programmed travel lenghts from the CAM program into a machine-specific control program.
Data Acquisition / Quality Assurance
Since spring of 2013, the lab will be provided with a 3D printer (Steinbichler).
The 3D printer is able to recognize already existing geometries and (after having processed these data with appropriate software) to generate a digital model out of them. Another postprocessing of the raw data allows to reverse the ruled geometries and freeform surfaces to such a degree that they can be used for parametric postprocessing or modification in the CAD system.
The model size is very variable. After having produced a component, its quality (i.e. dimensional accuracy) can be tested by means of the 3D scanner. The components range from milled parts to rapid prototyping models that might have layer thicknesses within micrometers.
