Three-dimensional Topography Simulation Research of Diamond-wire Sawing Based on Matlab

Abstract

The influence law of the surface topography and roughness by processing parameters of diamond wire-saw slicing simulation is researched in this paper. At First, the wire saw slicing model is built. The position relation between the wire saw and the machining surface is definite in the model. The motion trajectory of the diamond abrasive on the wire saw is generated. Processing the motion trajectory of the diamond abrasives and the 3D topography of the slicing surface is generated. According to the 3D topography and the roughness formula, the surface roughness can be calculated. Finally, by changing machining parameters, such as wire saw linear velocity and workpiece feed velocity, the corresponding surface roughness will be obtained. Therefore, the influence law of wire saw linear velocity and workpiece feed velocity on the surface roughness is studied. The influence law provides a theoretical basis to improve the quality of wire saw slicing.
