ABSTRACT
NC simulation is NC machining process in virtual environment mapping. As an
important part of virtual manufacturing, it can be used to test the NC code is correct and to
judge whether there had been cut, rough cut leakage phenomenon, to shorten the product
development cycle has important practical significance.
Based on the analysis of the domestic and foreign existing3D simulation modeling
theory and method based on the discrete modeling technology, introduced to the NC milling
simulation modeling, put forward to include triangle based discrete modeling method for
processing environment form construction, based on geometrical modeling method of tool
path bounding box cutter and blank intersection algorithm and based on the display list and
vertex search algorithm simulation optimization algorithm C milling simulation method,
and the related key technologies are studied.
Based on mon geometric modeling methods advantages and disadvantages, and
for three axis NC milling machining features, is proposed based on discrete modeling of three
axis NC milling simulation modeling method. Put forward considering of effect and
efficiency of three axis NC milling
