<Process Example>
By executing kerf check, the kerf position misalignment can be automatically corrected.

Step Cut Processing
After grooving with Z1, if Z2 makes a full cut on the same line, it is difficult to confirm the Z2 kerf (refer to Figure 2). By grooving separate lines, as shown in Figures 3 and 4, it is possible to execute kerf check for Z1and Z2.
The Z2 kerf is difficult to recognize due to the existence of the Z1 kerf. |

Short Kerf Check Function (Patent Pending)
When executing a step cut, normally the Z2 does not cut the workpiece surface.
However, since the workpiece surface is cut for kerf checking, blade damage
occurs due to the TEG and film coating on the workpiece surface and there is an
increase in backside chipping due to processing after kerf checking. To curtail
blade damage and backside chipping use the ” Short Kerf Check Function” to
control the cut stroke during kerf checking (available as an option).
