Abstract:

During the drilling, the drill bit impacts the rock, creating holes to serve the technological process in mining, industrial and civil construction, etc. The power consumed in drilling is spent to the rotation and the force of the drill bit. In order to design of rotary drilling machines and also to select drilling machines, drill bits, reasonable drilling modes suitable for rock properties, it is necessary to study the power consumption for each drilling process. This paper introduces some research results on power consumption distribution of small diameter polycrystalline diamond compact bit during the rock drilling
