High Performance Twist Drill Design and Drilling Operations for Machining Mould Steel

在本项目中，将开发一种基于低钻削力和高钻削寿命标准的高性能钻尖设计，它将与计算机应用软件一起开发，用于钻削力预测，基于“统一通用的切削法”，基于多约束钻削优化分析，以最小成本和每孔时间为目标的最优钻进给量和速度选择。将特别注意钻尖几何形状的制造。预计该应用软件将使钻机的设计、制造、性能和钻探条件相结合。

In this project a high performance drill point design, based on low drilling forces and high drill-life criteria when machining mould steel will be developed together with a computer application software for drilling force predictions, based on the ¡®unified-generalised mechanics of cutting approach¡¯, and optimal drilling feed and speed selection for minimum cost and time per hole, based on a multi-constraint drilling optimization analysis. Particular attention will be given to the manufacture of the drill point geometry. It is anticipated that the application software will enable the drill design, manufacture, performance and drilling conditions to be integrated.
