Title: Felling Head Cut Rate Control
The following references and brief descriptions are included with regard to their disclosed saw control methods:
US7017460, Method and arrangement for adjusting feed rate of a crosscut saw; A method controlling a crosscut saw feed force and/or a rotating rate of a cutter chain revolving around a guide bar of the crosscut saw. This method includes measuring the present feed rate of the crosscut saw, adjusting the feed force of an actuator controlling the crosscut saw and/or the rotating rate of the cutter chain revolving around the guide bar, determining an effect of the performed adjustment on the present feed rate of the crosscut saw, and concluding a next adjustment to be performed from the size of the change in the feed rate for continuously achieving a highest possible feed rate and continuing the adjustments until the wood is cut.
US6041683, System for adjusting the rotation speed of a cross‐cutting saw of a tree handling machine, especially grapple harvester; This invention is based on the idea of measuring the rotational speed of the cross‐cutting saw and according to the measurement adjusting the feeding power of the guide bar or other structure that supports the sawing blade, whereby the rotational speed is kept substantially constant.
US4644832, Method for monitoring saw blade stability and controlling work feed rate on circular saw and bandsaw machines; A method of controlling vibration in saw blades comprising: detecting lateral movement of saw blade; using signal conditioning means to provide an electrical signal proportional to said saw blade movement; calculating referenced mean displacement, peak to peak, and displacement RMS signals; comparing the conditioned signals to assigned levels; and controlling the speed of the saw blade responsive to said comparison by predetermined program logic.
US5845689, Feed rate control system for stump cutters; A method for operating an engine of a stump cutter involves sensing a condition of a component of a stump cutter having an engine wherein the condition is a function of a speed of rotation of the engine and controlling movement of the stump cutter toward a stump based on the function of the speed of rotation of the engine. For purposes of the present invention, the controlling involves reducing a speed of advancement of the stump cutter toward the stump when the speed of rotation of the engine is below a predetermined speed of rotation, increasing a speed of advancement of the stump cutte...
