Automatic Generation of Toolpath for Sculptured Surface Machining

SAE Technical Paper Series, 1996
<div class="htmlview paragraph">Based on a 3D model generated in a CAD system, a rapid prototyping system can manufacture a prototype in few hours. The most common techniques for rapid prototyping use materials like resins and polymers. The difference between the material of the manufactured prototype and the real piece makes the realization of ...

Adaptive Toolpath Generation for Wire Geometric Elements in Cyber-physical System for Cobotic Finishing

2024 IEEE 20th International Conference on Automation Science and Engineering (CASE)
Conventional machine tools, such as CNC machines, were mainly used for finishing applications, however they lack flexibility. Over the past decades, industries have increasingly turned to robotic solutions as a cost-effective alternative capable of ...

A novel boundary-first mapping method for jewelry CNC machining toolpath generation

Other Conferences
With the popularity of 3D scanning and measuring techniques, the advanced jewelry manufacturing enterprises tend to machine directly on the raw blanks that contain varying degrees of shape errors, which necessitates an effective mapping method to ...

Boundary-conformed toolpath generation for trimmed free-form surfaces

Computer-Aided Design, 2003
In this paper, we adopt a 2D reparameterization procedure to regenerate boundary-conformed toolpaths. Three methods for the 2D reparameterization of trimmed boundaries in parametric space are examined and compared. They are the Coons method, the Laplace method, and a newly developed boundary-blending method.

An improved toolpath generation algorithm for fused filament fabrication

2017 IEEE International Conference on Robotics and Automation (ICRA), 2017
Widely-used methods for toolpath planning in fused filament fabrication slice the input 3D model into 2D layers and construct a toolpath. In prior work (ICRA 2016) we gave a simple greedy algorithm that changed this paradigm and constructed the toolpath in 3D by printing local features in their entirety. This algorithm significantly improved upon layer-

Curve fitting with arc splines for NC toolpath generation

Computer-Aided Design, 1994
This paper investigates a biarc toolpath based on arc-spline theory, which reduces the storage and oscillation problems in conventional NC programming. The method uses continuous circular-arc segments to approximate the smooth curve. With a given tolerance, it can remove the excessive data point, and thus reduce the size of the NC program. It should be

Toolpath generation for diamond shaping of aspheric lens array

Journal of Materials Processing Technology, 2007
Abstract Micro lens array is popular in opto-electrical applications, including back-light module of flat display devices and white-light LED illumination. The paper is to develop a toolpath generation software for precision shaping of micro aspheric lens array (ALA) with an ultra precision 4-axes free-form single point diamond turning (SPDT) machine

A geometric approach to boundary-conformed toolpath generation

Computer-Aided Design, 2007
Isoparametric or streamline-like toolpath generation is an important method for CNC surface machining. For a trimmed surface, the generation of such a toolpath is not straightforward because by simply following the isoparametric curves of the parametric surface to generate the toolpath, the resulting toolpath may no longer conform to the trimmed ...

Toolpath Generation for Additive Manufacturing Using CNC Milling Machine

2018
Additive Manufacturing (AM) systems have gained popularity, due to their capability of producing parts in layer-by-layer manner with any degree of complexity. Although in the last three decades, various commercial AM systems have been developed, however, high cost of the indigenous materials used in commercial machines is the major hindrance for wide ...
