1 – Taper. Whether it is an I.D. or O.D. operation, taper is one of the most common problems in grinding and finding the cause can be tough. In some cases, it is as simple as adjusting the oscillation stroke to be longer or shorter to compensate. In others, dressing a reverse taper into the wheel may be the best way to handle things.

The back-end process: Step 3 – Wafer backgrinding
With a 2000 grit grinding process, the stress required to break the die was 50 percent higher than the stress needed to break a die with a (larger) 1200 grit grinding process. Figure 2 shows the method of applying the test force to the die, and Figure 3 shows the difference in the scratches on the wafers using different grits to grind the silicon.

Tips for Improved Surface Grinding | Norton Abrasives
For traverse surface grinding that alternates between upcuts and downcuts, a large step over: 50% or more, for example, may induce heat generation. A 50% step over means that 50% of the first will be ground again in the second pass, and so on. For example, if the wheel is 2" wide, the second pass will regrind 1" of the previous pass and 1 ...
