Reliability Analysis of the Efficiency of a Rotary Drilling Machine under Optimal Operating Conditions

Rotary hammer drills play a crucial role in various drilling operations; where performance and durability are essential. This study examines the impact of axial forces; directly linked to optimal rotational speeds, on operational efficiency. Chip thickness, a critical parameter, is determined using formulas developed by Rakov, Pereltoltchine, and Alimov, which incorporate factors such as rock hardness and axial force.
