El corte asistido por vibración (CAV) es una técnica de mecanizado que brinda mejor acabado superficial, reduce fuerzas en el corte y aumenta la vida de la herramienta. Para predecir de forma geométrica la topografía de un cilindrado con CAV se h

Publikováno v: Advanced Materials Research. 498:195-200

In this paper, we have developed a physical model to predict the forces of the ball burnishing. The models have been constructed on the basis of the plasticity theory. During the model development we have Fig.d out the dimensionless numberBthat chara

Publikováno v: Materials Science Forum. 526:235-240

The objective of this work is to develop thermal simulation software of the honing process applied to metallic cylinders. The proposed thermal model is based on the action of heat impulses generated by the abrasive bars that are in contact with the c

First of all, this work refers to the study of the ball-burnishing process assisted by a vibration. It starts by considering that this vibration helps to make the development of this finishing process easier, because it helps to deform the workpiece

In this paper, a numerical model was used based on the tool-piece geometric intersection, which enables the determination of a roughness profile as a function of feed, tool radii and tool eccentricity in side milling processes. Average roughness Ra a
