Last month, Georgia Tech students used SculptPrint to produce a complete centrifugal compressor. A housing for the impeller featured in the last blog post was sculptprinted on an Okuma Multus B-300 5-axis millturn machine. SculptPrint features supporting boring operations were used extensively to produce the inner diameter geometry of the housing.
The voxel model of the compressor housing in the SculptPrint software is shown below.
The millturn machine allows a mixture of turning and milling pass to produce the asymmetric geometry of the housing.
A boring pass on the inner diameter is shown below.
A milling pass to produce the asymmetric outlet port geometry is shown next.
A turning pass as modeled in SculptPrint is shown below.
A collision free milling pass on the inner diameter modeled in SculptPrint is shown next.
Finally, the test rig for the assembled compressor is shown. The compressors was tested up to around 2800 rpm with good results.
Georgia Tech students used SculptPrint to generate CNC paths for a turbocharger impeller. The impeller was produced on an Okuma Multus B-300 5-axis millturn machine. The tool paths were automatically assigned collision free orientations using SculptPrint’s access map technology. The students are also working on a housing for the impeller to complete the turbocharger.
The part modeled in SculptPrint using voxel modeling and access map technology shown below.
The image above show the “Candle Holder” geometry produced at Georgia Tech on their Mazak VCU 500 5-axis mill. The aluminum part has difficult to access spirals. SculptPrint’s advanced GPU technologies such as voxel modeling and access maps made producing this shape possible.
The image of the voxel model in SculptPrint is shown below.
In April of 2016, SculptPrint was featured at nVidia’s GPU Technology Conference. Demos of the software were given in our booth as well as in nVidia’s Design and Manufacturing section of their booth. The slides from the talk given at the conference are now available on nVidia’s website and can be found here.
