Assignee: JOY GLOBAL SURFACE MINING INC
Field: Civil engineering (Other fields)
Classification: CPC E | IPC E

Claim 12:
13. A mining machine with a virtual track modeling system, the mining machine comprising:
a frame;
tracks supporting the frame and configured to be driven to move the frame over a ground surface;
a dipper supported by the frame;
a dipper drive coupled to the dipper and configured to move the dipper in a dipper motion selected from the group of a swing motion, a crowd motion, and a hoist motion;
a dipper position sensor configured to determine a position of the dipper relative to a three dimensional mining machine coordinate system; and
an electronic controller including an electronic processor and a memory, the electronic controller coupled to the dipper drive and the dipper position sensor, the electronic controller configured to:
move the dipper to a first position associated with the tracks;
determine a first data point associated with the first position;
move the dipper to a second position associated with the tracks;
determine a second data point associated with the second position; and
generate a virtual model of the tracks by extrapolating virtual boundaries of the tracks from the first data point and the second data point.
