Abstract
A bandsaw (,) and bandsaw controller (,) adapted for control f at least one of the feed rate, cutting force and cutting speed of a bandsaw blade (,) as the blade cuts a workpiece (,). The controller includes an input device (,) 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 (,) 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 (,) exits from the workpiece (,). A method of operation of the bandsaw (,) to effect saw blade break-in and prevent detrimental saw blade break-through also is provided.
