Saw system, including methods and apparatus, for cutting pieces of stock to be installed end-to-end to form miter joints. In some embodiments, the saw system may include a computer that determines an appropriate saw pivot angle for cutting a proximal end of a second piece of stock, based on a corner angle entered for cutting a distal end of a first piece of stock. In some embodiments, the saw system may compensate for an offset pivot axis of a saw device based on entered lengths of cut first and second pieces generated respectively with the saw device pivoted to the left and to the right.

A device for machining the edges of casting strands includes one machining tool each that can be brought into contact with a longitudinal edge of the casting strand, and at least one guide element for perpendicularly applying the machining tools to the longitudinal edges. Means are provided for moving the machining tools in parallel to the longitudinal edges of the casting strands, in order to modify the relative speed between the longitudinal edges and the machining tools.

A method of processing a workpiece having a beveled edge on its outer circumferential portion to cut off a part of the outer circumferential portion includes placing the workpiece on a holding surface of a chuck table that is rotatable about a table rotation axis, forcing a cutting edge portion of an annular cutting blade to cut into the beveled edge while the cutting blade is rotating about a blade rotation axis, and rotating the chuck table about the table rotation axis, thereby cutting into the beveled edge with the cutting blade to cut off a part of the workpiece. While the cutting blade is cutting into the beveled edge, the table rotation axis and the blade rotation axis do not intersect with each other.
