Operational dynamics of the cutting head of the AM-50 heading machine

Abstract

Operation of the cutter head of an AM-50 heading machine is influenced by a large number of factors, many of them of a random character. Forces acting on each of the cutting tools participating in coal or rock cutting are determined and summed up. The total cutting force is then calculated and on that basis the turning moment is derived. Cutting tool operation also is analyzed as a stochastic process. Cutting forces of each cutting tool change from 0 to maximum. However these forces are distributed in cutting time and the total cutting force is not the sum of the average cutting forces, nor is it the sum of maximum cutting forces. Using calculus of probability, the probable force distribution was determined. This distribution is compared to force distribution calculated on the basis of power consumption of the cutter motors. The differences between the two force distributions are, among others, caused by insufficient investigation into operation of conic cutters. 10 refs.
