Abstract
A fence device includes a coordinate system for providing accurate positioning of a workpiece along two perpendicular axes. Precise repeatable positioning of the workpiece relative to a given reference point is achieved. Two or more separate calipers are used for the positioning. The device includes parallel channels along two opposing edges of a table top. Channel guides along edges of a fence engage the channels for movement of the fence toward and away from a cutter bit or other material removing tool. A first caliper determines the distance that a workpiece may be moved when engaging the cutter bit. The location of a workpiece along the fence is determined using a second caliper perpendicular to the first caliper. A slide plate is secured at right angles to the fence and uses the second caliper to accurately position the distance of the fence with relation to the tool.
