Abstract
A vacuum hold down table includes a surface sheet having perforations arranged so as to reduce surface cracking when the surface sheet is subject to forces during use of the table; the perforations may also be arranged to that a greater hold down force is produced in that portion of the table where the workpiece will be located, this may be accompanied by varying the hole diameter and/or hole spacing.
