Five-axis machining of STL surfaces by adaptive curvilinear toolpaths

摘要: We propose a new framework for toolpath generation five-axis machining of part surfaces represented by the StereoLithography (STL) format. The is based on flattening STL and adaptive curvilinear toolpaths. corresponding cost functions, designed to represent accuracy efficiency toolpath, are scalar such as curvature, kinematic error, rotation angles, strip or material removal rate vector field when tool moves along path partly even entirely aligned with directions considered be optimal. exploits grid methods biased space-filling curves, combined adaptation boundary domain decomposition. proposed methodology (ACT) has been tested variety surfaces, including case study dental parts. Machining crowns/implants four basic types human teeth, molar, premolar, canine incisor...
