Abstract

The wear of cutting elements of auto graders allowed in practice causes an increase in the cutting force by 3 to 4 times, the energy intensity of the cutting process by 1.4 to 3 times, the cost of soil development by 8 to 15 % with a decrease in productivity by 10 to 30 %. This increases the stress state of the entire machine and reduces its operational reliability. Excessive wear of cutting elements leads to economic inexpediency or practical impossibility of further operation of machines.
