It is advisable famed that pure mathematics parameters of the drill point, i.e., indemnity angles, deceive structure and web size, have a major determinant on the drill's performance. This writing assignment deals with the determining factor on the drill life of some geometrical errors which were often whole neglected in drilling tests. Two different drill groups of different manufactures were tested.
Experiment Study of the Soft Rock Materials Based on Rotary Penetration Test
Based on the new-style synchronous converter penetration instrument, the rotating-incising-drilling try out for the demanding stone material are tested in this paper. The conclusion is that rotary incoming test can more effectively improve the drilling capacity than cone penetration run victimisation in effortful bed specified as soft rock、hard loess and so on, and reduce bit pressure without rising the ability of instruments based on the factor that using rotary drilling or else of point-blank drilling. promote analyses have shown that the qualitative relationships 'tween circular onrush test information and basic physics parameters can be preliminarily obtained.
