An Improved Method for Haptic Tracing of a Sculptured Surface
نویسندگان
چکیده
1.0 ABSTRACT We present an improved method for directly tracing a sculptured surface. This method extends previous work by adding secondorder surface information to a closest point tracking algorithm which greatly increases the stability and also improves the accuracy of the algorithm. As part of the derivation of the new method, we examine in detail the system of equations that tracks the closest point on the surface and highlight surface features that can cause problems. We then address these potential problems.

Direct Haptic Rendering Of Sculptured
A new tracing algorithm is described that supports haptic rendering of NURBS surfaces without the use of any intermediate representation. By using this tracing algorithm in conjunction with algorithms for surface proximity testing and surface transitions, a complete haptic rendering system for sculptured models has been developed. The system links an advanced CAD modeling system with a Sarcos f...
متن کاملHaptic Rendering of Surface-to-surface Sculpted Model Interaction Dsc-3-4
Previous work in haptics surface tracing for virtual prototyping and surface design applications has used a point model for virtual finger-surface interaction. We extend this tracing method for surface-to-surface interactions. A straightforward extension of the point-surface formulation to surface-surface can yield extraneous, undesirable solutions, although we rework the formulation to yield m...

An instantaneous rigid force model for prediction of cutting forces in ball-end milling of sculptured surfaces is presented in this paper. A commercially available geometric engine is used to represent the cutting edge, cutter and updated part geometries. The cutter used in this work is an insert type ball-end mill. Intersecting an inclined plane with the cutter ball nose generates the cutting...
