Iso-level tool path planning for free-form surfaces
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, while the tool path should be smooth enough to maintain a high feed rate. However, iso-scallop and smoothness often conflict with each other. Existing methods smooth iso-scallop paths one-by-one, which make the final...
متن کاملTool Path Planning for Machining Free-form Surfaces
This paper is about new iso-parametric tool path planning for machining trimmed freeform surfaces. The trimmed surface has been re-parameterized by two different parameterization techniques, namely, the partial differential equation method and the newly developed boundary interpolation method. The efficiency of the scheme has been measured in terms of path length and computational time needed f...
متن کاملFitting of Iso-Surfaces Using Superquadrics and Free-Form Deformations
Recovery of 3-D data with simple parametric models has been the subject of many studies over the last ten years. Many have used the notion of superquadrics introduced for graphics in Bar81]. Diierent improvements were introduced to make the model a better representation of the data BG87, FLW89, SB90, TM91]. This paper describes a two-steps method to t a parametric deformable surface to 3-D poin...
متن کاملTool Path Generation for Milling of Free Form Surfaces With Feedrate Scheduling
The use of freeform (sculptured) surfaces in the product design process is accelerating at an exponential rate driven by functional as well as esthetics demands. CAD/CAM software is a must in their design and manufacture. While the geometric aspects of the design are relatively wellcovered, issues still remain when it comes to the actual manufacture of freeform surfaces. The major issues are re...
متن کاملTool orientation planning for five-axis CNC machining of open free-form surfaces
For the geometry characteristics of open free-form surfaces, it is hard to consider global interference during the planning of feasible domains. Therefore, the optimal kinematic orientation of tool axis will no longer be confined to the boundary of feasible domains. In this paper, according to the principle demanding that the tool should be fitted to a surface as close as possible and relevant ...
