Electroplated single-layer grinding wheels, in spite of offering unique useful features like geometrical flexibility, large chip accommodation volume in the inter-grit space, etc., produce high transverse surface roughness on the ground surface of the workpiece. Non-participation of all the superabrasive particles (grits) attributes to this ...

Based on Eq. (1), the trajectory of a single grain during UAG is a 3D sinusoidal curve (as shown in Fig. 2).The effect of changes in abrasive grain trajectories on the grinding process is further illustrated in Fig. 3; compared to CG, interactions and overlapping of trajectories originating from different abrasive grains are significantly …

Characterization of the grinding-induced SSD in silicon wafers is complex. Although a nanometer-deep cut induces a nanostructure 17 or amorphous layer 18,19 on a silicon wafer during grinding, a deeper cut induces SSCs. Of these three types of damage, SSCs are the most detrimental.

Grinding is a powdering or pulverizing process using the rock mechanical forces of impaction and attrition. The two main objectives for a grinding process are: To liberate …

This study presents a comprehensive and comparative investigation on creep-feed grinding (CFG) of single crystal nickel-base turbine blade fir-tree roots with and without surface burn by using alumina abrasive wheels, in terms of tool wear, grinding force, temperature, and surface integrity. For both cases (i.e., with and without grinding …

The research was based on the analysis of data obtained from measurements of single-layer grinding wheels using the replica technique.

Errors that were computed related to the ...

The causes of low profiling efficiency are as follows: when the multiple layering and layer-by-layer cutting method is used to tangentially profile a grinding wheel, with the continuous removal of the material on the grinding wheel's surface, an increasing amount of laser energy directly passes through the grinding wheel's surface, which ...

1. Introduction. Severe plastic deformation processes (i.e., surface mechanical grinding treatment (SMGT), surface mechanical attrition treatment (SMAT), severe torsional deformation (STD), and high-pressure torsion (HPT)) are the common methods to modify the properties of surface layer of metals via grain refinement [1], [2].If …

In this study, we intend to explore grinding performances of single- and dual-layer DP composite deposit with an average DP size of 150 μm, referred to as D-150.

This study explored the performance of electroplated grinding tools electroplated with single and dual-layer diamond particles (DPs). These tools were fabricated through a three-step electroplating process, involving Ni-undercoating, Ni-diamond co-electroplating, and Ni–B strengthen-electroplating, on AISI 440C steel rods. …

Once the grinding force acting on the working surface of the grinding tool reaches a certain threshold, micro- and macro-fractures may occur in the grinding grain. During the wear process of CIB and UVAIB single-layer cBN abrasive tools, the normal grinding force F n, the tangential grinding force F t and the force ratio F n /F t are ...

For the single-layer brazed CBN wheel, the grinding temperature rises from 433 °C to 713 °C (by 65%). The reason for the above-mentioned variation phenomenon is that higher workpiece infeed speed or larger depth of cut always results in larger tangential force (Fig. 5). As a consequence, more heat flux enters the grinding zone, which …
