The Effect of Drill Flank-Wear on the Cutting Resistance
Abstract
본 논문에서는 drill의 측면마모가 torque와 thrust에 미치는 영향에 관해서 연구하였다. 측면마모의 주절삭날에 따른 분포를 2차원 절삭에 적용되는 Taylor's too-life equation을 이용해서 ??로 가정하고 torque와 thrust에 관한 식을 유도하였다. 그 결과 wear land가 4.2×10??인치 정도에 도달했을 때 flank wear에 의한 torque와 thrust가 전체 torque와 thrust에 각각 약 10%, 2%에 해당되었다. 그러므로 절삭동력을 구할 ?? flank wear에 의한 영향을 고려하여야 한다.
In the present paper, it is studied on the effect of flank wear on the cutting resistance in drilling.

The equations for torque and thrust are derived from the assumption that the profile of flank wear along the main cutting edge is ??. This expression is obtained by using the Taylo'r tool-life wquation applied to the porhogonal cutting.

The result of this paper is that 10% of total torque is the torque due to falnk wear as wear land is reached at 4.2×10?? in. and the effect of thrust is 2% of tatal thrust at the same time.

Therefore, the effect of flank wear must be considered in obtaining the cutting tesistance.
