Abstract:
1. A method of preparing a workpiece for use in a miter joint, comprising: mounting a saw to a stand, the saw defining a cutting path; mounting a rail module to the stand, the rail module including a fence having opposite ends and extending parallel to a measurement axis that intersects the cutting path to define an origin, the rail module also including a stop movably connected or movably connectable to the fence; mounting a motor box including a motor and a controller formed as a unit to the rail module, such that operation of the motor drives travel of the stop along the measurement axis to different separations from the origin, wherein the motor box is interchangeably mountable adjacent each opposite end of the fence to drive the stop; entering into the controller a width and a target dimension of a product to be generated from a workpiece, the product having a miter at one or both ends; commanding the controller to position the stop with compensation for the miter such that the controller controls operation of the motor based on the width and the target dimension to drive the stop to an adjusted position spaced from the origin according to an adjusted dimension that incorporates at least one miter offset into the target dimension; and cutting the workpiece with the saw, while an end of the workpiece is disposed against the stop held at the adjusted position, to generate the product.
