Research on Influence of Row Spacing to Surface Roughness in Curve Surface Machining

The parallel milling is adopted to curved surface NC machining. The row spacing has an effect on surface roughness of workpiece. The influence law of row spacing to surface roughness of workpiece is concluded by experiment: with the decreasesing of row spacing, surface roughness value also subsequently reducde, surface precision gets higher also. when the row spacing reducs to a certain degree, the surface roughness will no longer decrease.
