碩士 === 元智大學 === 工業工程研究所 === 83 === An object-oriented computer-aided process planning system
forfeature-based prismatic parts is presented in this thesis.
The feature-based part model is created from a feature-base
design subsystem of an integrated concurrent engineering
system, named ICES. The presented system reduces the number of
cutting blocks by eliminating the overlapped features cutting
space that is resulted from feature overlapping in design
phase. The system can be customerized by supplying various user-
defined databases and knowledge bases to generate rofessional
and pertinent process plan.According to a range specification
for sharing tools, supplied by the users,the system thus assign
several processes share the same tool to reduce tool changing.
In this research, a hierarchial process planning framework,
which emphasizes and generates information of intermediate
workpiece shapes and specifications, is proposed. Based on the
concept of swept volumes of tool movements, different machining
process, and various tools, the system defines CutRegion3D
class, ProcessManager class, and ToolManager class.
ProcessManager class, and ToolManager class. ProcessManager
class is designated to management each machining process.
ToolManager class is designated for tool selection, which is
proceded by analying shape and function of each feature.
CutRegion3D class provides information and shape of
intermediate workpiece during manufacturing process, which
plays an important role in the related engineerings processes.
The presented process planning system for prismatic parts is a
sub-system of ICES, the integrated concurrent engineering
system ,to facilitate concrrent engineering to reduce the lead-
time of developing new products and avoid improper design.
