Abstract: NC verification has always been a difficulty of NC
machining. In recent years, the Web-based NC machining simulation has
become a popular research area, which currently faces the conflicting
requirements for high precision and real-time capability. A multi-branch
general lists structure is proposed to solve the above problem. The
general method of applying the VRML ElevationGrid node to build a grid
model of workpiece and its disadvantages are introduced. The
multi-branch general lists structure is defined, and the relevant
recursion arithmetic is represented. Compared to the common general
lists structure, the multi-branch general lists structure has the
advantages of dynamical depth and adaptive scale. The VRML super class
and remote control mechanism are constructed. The experiment of
Web-based simulation demonstrates that a model constructed by the
multi-branch general lists structure has a better effect of simulation
compared to static details modeling.
