Software predicts power tool heat

Tag : Power Tools

AEG's range includes more than 100 different types of tools,including hammers, percussion and diamond drills, angle as well asstraight grinders and jig and circular saws.
AEG products are meticulously tested before market introduction toensure high-quality and reliability.
To test new design concepts created with PTC's Pro/EngineerWildfire 2, the design team uses EFD.Lab for thermal and airflowconditions.
"We chose EFD.Lab because it was easy to use".
"For example, with EFD.Lab we do not need to define the fluid area- the software does this automatically" Worner said.
Most traditional fluid flow simulation programs require users tocreate "phantom" solid parts to represent the (empty) fluidregions.
This an extremely time consuming process since users need toidentify each region manually and then create geometry to fill it.
EFD.Lab saves users time and effort by automaticallydifferentiating between solid and fluid regions for internal andexternal flows to create the fluid domain.
"Testing prototypes with EFD.Lab enables the AEG design team tofine-tune new design concepts by using information that they haveamassed over the years as the basic building block for their newdesign work".
"By using EFD.Lab we are able to further fine-tune our designs toreach an optimised design much faster".
"On a recent project, we realised that we had already reached ourgoal for improved airflow with the very first prototype", accordingto Peter Henske, CAD Manager.
Power tools designed at the South German facilities are engineeredfor two different brands: AEG Power Tools and Milwaukee ElectricTools.
The tools are based on a common platform, which makes it possibleto modify the machine components for the different needs of users.
"The modular design gives the chance to realise two differentexterior designs".
"Different exterior design and internal components result incompletely different airflow in the machine".
"Testing each configuration would take a lot of time".
"But with simulation we can identify the effects caused by all thedifferent design options and ensure proper performance for allmachines based on the platform", Henske said.
