Abstract

This research proposes a model-based planning system for planning multi-axis 3D surface scanning machine. Firstly we describe a simulation system for performing collision avoidance, occlusion detection, and evaluating the measured portions of the surface. Then based on this simulation system, as our initial trial, we propose a simple path planning method to increase surface coverage and reduce measuring time by iterations. This research aims at measurement of complicated automotive parts, such as sheet metal parts and press dies. The implementation result shows the efficiency and automation of our approach.

Abstract

In this paper we propose methodologies and algorithms of NC cutter path generation for subdivision surfaces. We select Loop surface as the subdivision surfaces. A path plan including rough cut and finish-cut is developed based on the LoD (Level of Detail) property of subdivision surface. We generate a coarse mesh that covers the limit surface to implement the rough cut. For finish-cut we use ball-end mills and offset cutter contact data to generate cutter location data. In these two steps we use a Z-map model and a collision detection/correction method is presented for the interference-free of these two steps. We implement our methods and present machining results. All of these two kinds of cutter paths are computed rapidly and automatically.

Abstract

This paper describes a general method for reconstruction of a subdivision surface from polygon model or a set of scattered data points. The basic idea is to use the subdivision limit position to adapt the control mesh of the subdivision surface to the data points. This method is not a time consuming process involving global optimization. It does, however, fail to capture local characteristics of input model. Consequently, the proposed method is not suitable for generating a surface that precisely interpolates the input model, but it will be useful for quickly generating one that captures the overall shape constituted by the input model.
