Abstract

A workpiece processing method includes: a dresser preparing step of preparing a dresser of a predetermined thickness; a fixing step of fixing the workpiece and the dresser on a support member adjacently to each other in a first direction; a holding step of holding the support member by a holding table, after the fixing step is performed; and a cutting step of positioning a tool edge of the cutting blade at a predetermined height and cutting the workpiece and the dresser in the first direction by a cutting blade, after the holding step is performed.

First claim

What is claimed is:

1. A workpiece processing method for grooving a first and a second workpiece by a cutting blade, the workpiece processing method comprising:
a dresser preparing step of preparing a first and a second dresser of a predetermined thickness;
a fixing step of fixing the first workpiece, the first dresser, the second workpiece, and the second dresser on a support member, arranged in that order in a first direction and directly adjacent to each other in the first direction such that there are no gaps between the workpieces and the adjacent dresser(s);
a holding step of holding the support member by a holding table, after the fixing step is performed; and
a cutting step of positioning a tool edge of the cutting blade at a predetermined height and causing the cutting blade to perform cutting of the workpieces and of the dressers by moving the workpieces and the dressers in the first direction, after the holding step is performed.

2. The workpiece processing method according to claim 1 , wherein, in the fixing step, further comprising fixing an additional dresser, wherein the additional dresser is fixed on an opposing side of the first workpiece in the first direction from where the first dresser is located.

3. The workpiece processing method according to claim 1 , wherein, in the fixing step, further comprising fixing an additional workpiece, wherein the additional workpiece is fixed on an opposing side of the second dresser in the first direction from where the second workpiece is located.

4. The workpiece processing method according to claim 1 , further comprising providing a third workpiece and a third dresser, wherein the third workpiece and the third dresser are arranged on and fixed to the support member.

5. The workpiece processing method according to claim 1 , wherein the dressers comprise white alundum, green carborundum, diamond, and cubic boron nitride bound by a bond material.

6. The workpiece processing method according to claim 1 , wherein the dressers and the workpieces have substantially equal thicknesses.
