Circular hole recognition for STL‐based toolpath generation

Rapid Prototyping Journal, 2005
PurposeThis paper presents a unique method to recognize circular holes from 3D models in the STL format. The topological information generated by this method enables identification of holes and tool path generation for holes which should be drilled rather than milled.Design/methodology/approachA method based on a set of developed algorithms is used to ...

Comparison of Clustering Techniques for Feature-Based Toolpath Generation in Dieless Manufacturing

Volume 2B: Advanced Manufacturing, 2021
The aim of the current research is to compare the data clustering techniques for the geometrical feature extraction. The CAD models of the geometries are sliced to generate the data sets for clustering.

Simulation-based adaptative toolpath generation in milling processes

International Journal of Machining and Machinability of Materials, 2014
Milling toolpath is often designed according to a CAD model which is not always an accurate representation of the real part. In an industrial framework, a significant geometrical variability is sometimes observed in parts that belong to the same batch. Therefore, the conventional approach makinguse of a unique nominal toolpath for manufacturing series ...

Automatic Generation of Interference-Free and Posture-Smooth Toolpath for Robotic Belt Grinding of Complex Workpieces

IEEE/ASME transactions on mechatronics, 2023
Robotic belt grinding has shown great potential to achieve automatic machining of high-precision parts. However, its productivity in machining complex parts has been greatly limited by the problem that interference-free and posture-smooth toolpath ...

Direct 3D Layer Metal Deposition and Toolpath Generation

Volume 1: 34th Design Automation Conference, Parts A and B, 2008
Multi-axis slicing for solid freeform fabrication (SFF) manufacturing process can yield non-uniform thickness layers, or 3-D layers. Using the traditional parallel layer construction approach to build such a layer leads to a staircase which requires machining or other post processing to form the desired shape.

Toolpath Generation for High Density Spatial Fiber Printing Guided by Principal Stresses

Composites Part B: Engineering
While multi-axis 3D printing can align continuous fibers along principal stresses in continuous fiber-reinforced thermoplastic (CFRTP) composites to enhance mechanical strength, existing methods have difficulty generating toolpaths with high fiber ...

Reinforcement Learning for Generating Toolpaths in Additive Manufacturing

2018
Generating toolpaths plays a key role in additive manufacturing processes. In the case of 3-Dimensional (3D) printing, these toolpaths are the paths the printhead will follow to fabricate a part in a layer-by-layer fashion. Most toolpath generators use nearest neighbor (NN), branch-and-bound, or linear programming algorithms to produce valid toolpaths.

HSM toolpath generation with capsule-based region subdivision

The International Journal of Advanced Manufacturing Technology, 2018
High-speed machining (HSM) has become a research hotspot in the manufacturing field these years. In HSM, it requires the toolpath to be very smooth. Any sharp corners will cause decelerations of the feed axes. However, corners are inevitable in the toolpath generation process. This work focuses on smooth toolpath generation for HSM pocketing.
