Abstract:
Based on analyzing various factors influencing milled surface
topography, firstly, a generalized model for milled surface
topography is proposed. Secondly, using the principles of
transformation matrix and vector operation, the trajectory
equation of cutting edge relative to workpiece is derived. Then,
a three-dimensional topography simulation algorithm is
constructed through dividing the workpiece into regular grids.
Finally, taking the peripheral milling process as an example,
the generalized model is simplified, and the corresponding
simulation examples are given. The results indicate that it is
very efficient for the generalized model to be used to analyze
and simulated the peripherally milled surface topography.
