ABSTRACT:
A control system for automatically controlling a work implement of an excavating machine through a machine work cycle in disclosed. The work implement including a boom, stick and bucket, each being controllably actuated by at least one respective hydraulic cylinder. A plurality of command signal magnitudes associated with at least one hydraulic cylinder are stored. The command signal magnitudes are represented by a plurality of control curves, where each control curve is responsive to a material condition setting that is representative of a predetermined condition of the excavating material. A microprocessor selects one of the plurality of control curves and responsively produces a command signal having a magnitude dictated by the selected control curve. A electrohydraulic system receives the command signal and controllably actuates predetermined ones of the hydraulic cylinders to perform the work cycle.
