96-detc/dfm-1410 Modeling and Nc Programming for Free-form Surfaces by Haptic Interfaces
نویسندگان
چکیده
The haptic interfaces were developed and applied to freeform surface CAD/CAM systems to improve the user interaction with geometric models. Two types of haptic interfaces were designed; a passive force feedback device and an active force feedback device. Two application systems were developed with these devices; the surface modeling system by the passive force feedback device, and the NC programming system by the active force feedback device. In the surface modeling system, the operator can generate the surface geometry by cutting the virtual clay model. In the NC programming system, the operator can directly teach the NC program by tracing the model with active force feedback device. The structure, control method, simulation software and representation of the geometric model in these systems are discussed. The performance and operating efficiency and accuracy of the systems are experimentally examined.

Offsetting surface boundaries and 3-axis gouge-free surface machining
A key issue in the creation of error-free tool path for numerically controlled (NC) surface machining is gouging (over-cut> prevention. In the case of solid-based machining, where the creation of tool paths across several surfaces in a single pass is imperative, the major sources for gouging are the tangent discontinuity (C’ discontinuity) and the surface gap (Co discontinuity) occurred in the ...
متن کاملA novel haptics-based interface and sculpting system for physics-based geometric design
Standard free-form splines such as B-splines and NURBS are widely employed in a wide range of CAD/CAM systems. Conventional geometric modeling and design techniques using these popular splines often requires tedious control-point manipulation and/or painstaking constraint specification (for functional requirements) via unnatural mouse-based computer interfaces. In this paper, we propose a novel...
متن کاملVirtual Reality Simulation Modeling for a Haptic Glove
The recent addition of force and touch feedback to Virtual Reality simulations has enhanced their realism. Research on haptics interfaces is now extended to physical modeling of contact surfaces, object hardness, surface deformation, etc.. This is especially needed when dextrous manipulation of virtual objects is concerned. This paper describes a VR system using a haptic glove (Rutgers Master I...
متن کاملDETC 00 / DFM Information Modeling of Conceptual Process Planning Integrated with Conceptual Design
Conceptual process planning is a key activity for designers to evaluate manufacturability and manufacturing cost and time in the early product development stage. Since major manufacturing cost is determined in early design, it is critical to be able to assess manufacturability and cost as early as possible in the design process. The integration between process planning and design is critical to...
متن کاملAugmenting Interactive Tabletops with Translucent Tangible Controls
Multi-touch surfaces enable multi-hand and multi-person direct manipulation interfaces. However, they lack haptic feedback. Tangible interfaces (TUIs) are a promising approach to this issue but most are special-purpose with fixed physical and visual appearance. This chapter provides an overview of recent work to add haptic feedback to interactive surfaces, including haptic and tactile displays,...
