Abstract
A system includes a sacrificial board such as a cement board and containment support lid, sometimes referred to as a saw cup, is provided for use with a vacuum hold down support to allow cutting on top of normal suction cups by providing a temporary scorable surface in an assembly that is easily installed and removed, inexpensive to own, use and handle and which enables a user to go directly back to using a CNC machine for final edging and processing of the material without having to go to another location for sawing and without having to deal with heavy and unwieldy plates. Dimensions are such that any penetration of the cutting blade is intentional and will result in controlled scarring of the cement board which does not disable continued use of the saw cup. A one-piece molded saw cup is also illustrated.
