Abstract
A method and machine with an automated digging cycle is provided. The method includes moving an implement system of the machine through a work cycle, including interacting with a material. The method further includes sensing values associated with a bucket velocity parameter, such as bucket tip velocity, during interacting with the material, and controlling the velocity parameter via commands which control a sequence of bucket orientations whereby an implement system of the machine interacts with the material, responsive to the sensed values. The machine includes an electronic controller configured via a control algorithm to execute the automated digging cycle. A velocity based control system for an excavating machine includes an electronic controller configured to receive velocity signals from at least one sensor, determine a bucket tip velocity, and output control commands to move a bucket of the excavating machine through a material via a sequence of bucket orientations that is based on the determined bucket tip velocity.
