Analysis of the influence of speed of cutting land on stability of a spiral drill bit and ways of its increasing
This article presents the analysis of the influence of cutting speed and the thickness of a cut layer on stability of a cutting land. Based on the analysis there is considered the design of the cutting part of a spiral drill bit with more uniform distribution of stability of cutting points, compared to a usual drill bit. The authors established the equation describing the projection of a cutting land onto a plane perpendicular to the axis of the drill bit.
