- Abstract
- In a blown powder metal deposition process, a multi-axis hybrid manufacturing system, including a material deposition and a material removal system with more than 3-aixs mobility, is highly desirable in the building complex parts. However, the multi-axis planning process is quite complex. In order to address this issue, a parametric representation of STL-based layer geometry is presented in this paper for a multi-axis material deposition and removal process to build a fully functional part without support structures. This multi-axis process can build 3-D layers in which layer thickness is not uniform. By utilizing the advantage of five-axis motion to build non-uniform 3-D layers, the ability to deposit material without support structures is increased. However, in some cases, the deposition process cannot produce the desired geometry of a 3-D layer, and thus the machining process is needed. The algorithms presented in this paper reconstruct the parametric curve from the STL format for the machining process to achieve the desired accuracy by interpolating more points between given points.
