3. Operation

3.3.2 Positioning the workpiece

When the image is in focus on the screen, align the measured edge of the workpiece to

the measuring axis of the cross-travel stage. Move the workpiece or the fixture so as to

align the workpiece image with the cross-hair lines on the screen.

•

Rotary table (No.176-106, 172-196) is suitable for performing alignment.
