• Soil cutting
• Excavation force
• Excavator.

A better tool design in the excavation process has been always a challenging task for the engineers. A poorly designed tool always results in poor excavation of the ground, higher wear of the tool, wastage of the time, and power, and thus reducing the overall productivity of the excavation operation. But proper understanding of the soil mechanics in context of the soil cutting process may help in a better tool design. Moreover; in designing the control system for an excavator requires the dynamic model of an excavator, and it requires in turn the resistive forces offered by the ground on the bucket. The excavation forces necessary to cut the soil by the excavator bucket have been analyzed in this paper to improve the design of the bucket teeth, the leap plate of the bucket,and the side cutting plates. The method used for calculating the excavation force is based on 2D analytical soiltool interaction models.
