A note on solid modeling: history, state of the art, future
Qiang Zou
Solid modeling is a technique underlying CAD software as we see it today, and its theories and algorithms are among the most fundamental milestones in the historical development of…
Variational Direct Modeling: A framework towards integration of parametric modeling and direct modeling in CAD
Qiang Zou, Hsi-Yung Feng, Shuming Gao
Feature-based parametric modeling is the de facto standard in CAD. Boundary representation-based direct modeling is another CAD paradigm developed recently. They have complementary…
Towards computing complete parameter ranges in parametric modeling
Zhihong Tang, Qiang Zou, Shuming Gao
In parametric design, the geometric model is edited by changing relevant parameters in the parametric model, which is commonly done sequentially on multiple parameters. Without gui…
Parametric/direct CAD integration
Qiang Zou
In the history of computer-aided design (CAD), feature-based parametric modeling and boundary representation-based direct modeling are two of the most important CAD paradigms, deve…
Length-optimal tool path planning for freeform surfaces with preferred feed directions
Qiang Zou, Charlie C. L. Wang, Hsi-Yung Feng
This paper presents a new method to generate tool paths for machining freeform surfaces represented either as parametric surfaces or as triangular meshes. This method allows for th…
Robust and efficient tool path generation for poor-quality triangular mesh surface machining
Qiang Zou
This paper presents a new method to generate iso-scallop tool paths for triangular mesh surfaces. With the popularity of 3D scanning techniques, scanning-derived mesh surfaces have…
Iso-level tool path planning for free-form surfaces
Qiang Zou, Juyong Zhang, Bailin Deng +1
The aim of tool path planning is to maximize the efficiency against some given precision criteria. In practice, scallop height should be kept constant to avoid unnecessary cutting,…
Iso-parametric tool path planning for point clouds
Qiang Zou, Jibin Zhao
The computational consuming and non-robust reconstruction from point clouds to either meshes or spline surfaces motivates the direct tool path planning for point clouds. In this pa…
