The grinding wheel speed, grinding wheel grade, depth of cut, grinding wheel material and feed rate are the important parameters that affect the surface finish, which in turn affects the productivity and cost of the component. The grinding parameters used for both surface and cylindrical operations are tabulated in table 1.
As of last evening, my profits is now currently up $246,159 USD which is 1 step closer to my goal of $500,000 USD for this month. The grinding and the sleepless night became real and I am absolutely fatigue but I know the result is well worth it considering that I am a high achiever with laser sharp focus. Looking forward to the next trade tonight.
Fig. 1 shows the flowchart to calculate the grinding forces from the scratch test. It is worth mentioning that the single grain test was done at the feed speed, v w, of 5000 mm/min to prevent slots overlapping, different cutting depths, which represent different chip thicknesses in the micro-grinding process, and at the same cutting speed in which the grinding tests were carried out, i.e v c ...
A certain degree of surface micro-damage will be formed during grinding hardening process which mainly contains micro-crack, melting coating, decarburization, and surface scratch. In order to study the micro-damage of grinding hardening, the paper carries on a grinding hardening experiment and the characteristics of micro-damage are observed.
Grinding wheels come in many different sizes, shapes, and abrasives (Figure 5-7). Some of the various types are listed below. Straight Straight wheels, numbers 1, 5, and 7, are commonly applied to internal, cylindrical, horizontal spindle, surface, tool, and offhand grinding and snagging. The recesses in type

Two experimental setups were used for the micro-grinding and single-grain scratch tests. The micro-grinding tests utilized a KERN Pyramid Nano, high-precision, 5-axis, micro-machining center (Fig. 2a).Grinding and dressing parameters encompassed different cutting speeds (v c), feed-rate-to-depth-of-cut ratios (v w /a e), dressing feed rates (v ftd), and dressing speed ratios (q d).
An important factor throughout the Coarse Grinding and Fine Grinding Stages is that the scratches be uniform in size and parallel to each other in any one grinding stage. Proper grinding involves rotation of the sample by 90o between stages while the grinding angle must be held constant during the grinding at any one stage.

or 'micro-machining' [2], of optical components. Opticians1 have long used lathes to produce spherical 'tools' used in grinding and polishing operations. As early as 1648, Maignan (figure 1) described a polar coordinate tracer lathe for producing concave and convex metal optics; there is no evidence, however, that such a machine was built.

Grinding burn is caused by excessive heat produced during grinding process. It changes the surface hardness and reduces the fatigue resistance which brings great damage to work-piece [1, 2].Grinding burn is widespread in the field of cylindrical grinding, rail grinding, bearing rings grinding, and so on [3,4,5].Therefore, the detection and monitoring of grinding burn is of great …
