Abstract
This work presents a framework for machining burr minimization
in a CAD/CAM integrated environment. A four-level approach is proposed
based on experimental findings. First, design rules are established to realize
design for burr minimization. A set of process planning rationales is developed
for feature decomposition at the macro-planning stage. Look-up tables and
simple rules help determine burr-free cutting parameters at the
micro-planning stage. Special tool path planning algorithms are introduced for
avoiding exit burr formation in planar milling. This work demonstrates that burr
prevention can be effectively accomplished in an automatic manner through
CAD/CAM integration. Machining edge quality is thus significantly enhanced.
