Effect of Cutting Parameters on Materials Swelling of Machined Surfaces in Single-point Diamond Turning(Ultra-precision machining)

概要

論文の詳細を見る
The influence of materials swelling on surface roughness in single-point diamond turning was investigated. The normalized extent of swelling is characterized by the swelling significant index, defined based on power spectral density. Materials swelling was found to be significant in single-point diamond turning although it has been unnoticed in conventional machining. Experimental results from the power spectrum analysis indicate that the profile of tool marks is distorted by the effect of the swelling of the materials being cut. Copper alloys have more of a swelling effect than aluminum alloys owing to their higher ductility. The findings in the present study provide an important means for improving the surface finish of the diamond-turned surfaces.
