چکیده

In this paper, an implementation of visual and haptic feedback of deforming and cutting operations is discussed. In the implementation of the deforming operation, the surface shape is represented by a geometric model while the physical reaction is simulated using a spring model. The deformation of the spring model is reflected onto the geometric model by using the interpolation technique. In the implementation of the cutting operation, we realize visual and haptic feedback of the cutting operation remarking on the geometric and physical aspects, respectively. Combining the deforming and the cutting environment, we successfully implemented a work space in which we can form and design shapes through operations similar to clay modeling.

Effects of Helix Angle Variations on Stability of Low Immersion Milling

The stability behavior of low immersion helical end milling processes is investigated in this paper. Low radial immersion milling operations involve interrupted cutting which induces chatter vibration under certain cutting conditions. Time Finite Element Analysis (TFEA) is suggested for an approximate solution for delayed differential equations encountered during interrupted milling. An improve...

Expressive cutting, deforming, and painting of three-dimensional digital shapes through asymmetric bimanual haptic manipulation

Practitioners of the geosciences, design, and engineering disciplines communicate complex ideas about shape by manipulating three-dimensional digital objects to match their conceptual model. However, the two-dimensional control interfaces, common in software applications, create a disconnect to three-dimensional manipulations. This research examines cutting, deforming, and painting manipulation...

Free-form sketching

With the advent of sketch-based methods for shape construction, there’s a new degree of power available in the rapid creation of approximate shapes. Sketch [Zeleznik, 1996] showed how a gesture-based modeler could be used to simplify conventional CSG-like shape creation. Teddy [Igarashi, 1999] extended this to more free-form models, getting much of its power from its "inflation" operation (whic...

اکستروژن سه بعدی به روش میدان خطوط لغزش

Many metal forming problems have been solved using the slip line field method but all of them have either been two-dimensional (plane strain or plain stress) or axisymmetric problems. In this paper a procedure has been proposed by which the slip line field solution to three dimensional problems of metal forming becomes possible. For this purpose the extrusion of shaped sections has been taken a...
