Still, however, performance prediction is an important part of any TBM project. This is due to the general need for cost- and schedule-evaluations at the various planning stages of a tunnel project, as well as to develop the information necessary for a reliable comparison between alternative tunnel construction methods (TBM versus drill and blast).

Disk cutter is a working part of the tunnel boring machine (TBM), which is directly in contact with the rock, bearing a strong impact load and vibration, so the structure is very easy to have damage and failure. The accurate prediction of the cutter group load is the key to structure design of cutters.

The next calculation operation, which leads from net boring speed to rate of advance, must take account of obstructions, faults and interruptions to tunneling. In many cases, this is accomplished by multiplying net boring speed by a utilization factor [%], and in more precise calculation, by means of the assumption of downtimes in minutes or hours.
