High-precision metal cutting is increasingly relevant in advanced applications. Such precision normally requires a cutting feed in the micron or even sub-micron dimension scale, which raises questions about applicability of concepts developed in indu

International audience; Surface integrity directly affects the mechanical behavior of the workpiece, which is especially relevant on fatigue behavior. To characterize the quality of the machined surface, aspects such as material damage, roughness or

The ploughing force related with action of edge radius is an important factor which influences flow stress, chip formation or surface integrity. Some fraction of the cutting forces are called parasitic (additional) forces and they do not contribute o

Broaching is a widely used finishing operation for the manufacturing of transmission gears which are commonly made of steel AISI 1045. Therefore, there is a high interest for industry to understand the metal cutting process and modeling could shed li

Influence of chip segmentation of Ti64 on the topography of the machined surface

Publikováno v: AIP Conference Proceedings.

Chip segmentation is a common phenomenon that occurs during the high and low speed machining of Ti64. At low cutting speed the lack of ductility is the responsible for the segmentation of the chip, while for high cutting speeds the adiabatic shearing
