For dressing operations, the machine must be prepared accordingly by the machine manufacturer. The machine manufacturer may provide his own cycles.
The term “dressing” refers to the sharpening or trueing up of a grinding tool inside the machine. During dressing, the dresser machines the grinding wheel. Thus, in dressing, the grinding tool is the workpiece.
The dresser removes material and thereby changes the dimensions of the grinding wheel. Dressing the diameter, for example, causes the radius of the grinding wheel to become smaller.
