A New Method for Copper Spherical Surface Lathing with High Speed Steel Cutting Tool

Abstract:

On the basis of uneven copper surface roughness during lathering in common CNC lather, analyze the cutting ways of copper spherical surface and the cutting layer different from cylindrical surface lathing. The cutting direction of cylindrical surface lathing is constant, and its cutting layer is too. However, the direction of spherical surface lathing varies along the tangent of its cutting point continually, and the working cutting edge angle and the working minor cutting edge angle of the cutting tool vary too, so the theoretical surface roughness is affected. The cutting layer of spherical surface lathing varies continually, so does the cutting depth of its every cutting point. Through analysis and experiments, prove that cutting force variety is caused by the gradient variety of cutting depth, which leads to increase of the surface rough and its unevenness. Based on the research result, design some new cutting path to improve the surface roughness of copper spherical surface lathing, and obtain good effect.
