Abstract

A bandsaw (21) and bandsaw controller (39) adapted f or control of at least one of the feed rate, cutting force and cutting speed of a bandsaw blade (24) as the blade cuts a workpiece (26). The controller includes an input device (61) adapted to provide signals to the cutting rate control assembly including a cutting rate signal, a break-in mode signal and a break-through mode signal. The cutting rate control assembly is responsive to the break-in mode signal to begin cutting of workpiece (26) at a break-in cutting rate below the desired cutting rate and to increase the break-in cutting rate automatically, as a function of time until the desired cutting rate is achieved. The cutting rate control assembly is further responsive to the break-through mode signal to reduce the saw cutting rate just before the saw blade (24) exits from the workpiece (26). A method of operation of the bandsaw (21) to effect saw blade break-in and prevent detrimental saw blade break-through also is provided.
