Description
Summary:It is known that during the facing on a lathe, due to the cutting speed change along the workpiece radius, the generation of the built-up edge is possible. Because of this fact, a maximum of the surface asperities height could be highlighted. From the practical point of view, it is important to have information concerning the influence exerted by some input factors of the facing process on the values of the roughness parameters that corresponds to the surfaces obtained by such a machining process. An experimental research was designed and materialized to evaluate the influence exerted by the cutting speed, feed rate and turning tool corner radius on the values of the surface roughness parameters Ra and Rq. By mathematical processing of the experimental results, some empirical mathematical models were determined. One confirmed that a low value of the surface roughness could be obtained by using high turning speed and adequate values for the feed rate and turning tool corner radius.
