Performance of Brazed Diamond Tool for Machining Dental ...

Diamond tools are fabricated by brazing and used to machine dental ceramics in this paper. The morphology, grinding ratio, wear and grinding force of the brazed tools are investigated in comparison with that of the electroplated ones. The results show that the brazed alloy forms a hill-like structure around the diamond grits, and the protrusion of the brazed diamond grits is higher than that ...

Modeling of curved diamond wheel errors for improvement of ...

A superhard diamond grinding can machine the hard and brittle freeform workpiece, but it is difficult to control the form-truing errors of curved wheel-profile in multiaxial grinding. Generally, it needs multiple compensation grindings through the on-machine measurement of the ground surface, leading to inefficiency. Hence, the model of 2D wheel-profile errors is proposed to directly ...

Grinding Precision and Productivity Reach New Heights

Grinding, like all machining processes, is generally thought of as a process of tradeoffs. To gain one attribute, you have to sace another. However, that is not always true. For example, one logical attempt to achieve good material removal rates as well as limited wheel wear is to fix diamond or CBN super-abrasives in a sintered metal bond.

For adaptive control of cutting machining operations, measured quantities characterizing optimized productivity are utilized. These quantities are connected with the wear of the tool and with the wearing rate. To measure the wear, the face wear (also called crater wear) of the tool, its flank wear and its minor-flank wear are used. Other parameters used are: the dimensions of the workpiece ...

Fast tool servo/ slow tool servo (FTS/STS) diamond turning is a very promising technique for the generation of freeform optics. However, the currently adopted constant scheme for azimuth sampling and side-feeding motion possesses no adaptation to surface shape variation, leading to the non-uniform surface quality and low machining efficiency. To overcome this defect, this paper reports on a ...
