Abstract
In this paper, the influence of the waviness of tip arc profile on the surface quality of micro transition arc workpiece is studied. Firstly, the contour curve of the surface of the micro tool was measured by using the radius amplitude measuring instrument, and the characteristic parameters of the waviness in the contour curve were found. A simulation study of the effect of feed rate on the quality of the machined surface of a sine wave model with different characteristics was performed by Matlab. It can be known from the simulation results that when a sine wave of 0.05sin(10t) exists in the contour of the tool tip arc, when the feed rate is small, the impact on the surface accuracy of the workpiece is greater, and a sin wave of 0.02sin(30t) locally affects the regional surface roughness is greater. With the increase of feed rate, a sin wave of 0.02sin(30t) has no effect on the surface roughness of the partial area, while a sin wave of 0.05sin(10t) still has a greater effect on the surface roughness of the partial area.
