钻孔是制造企业最常用的加工工艺之一，从科学研究的角度来看非常复杂。几何体和曲面是在具有许多影响参数的单个操作中生成的。当减少或消除切削液的使用时，几何和尺寸控制更为关键，因为工艺中的温度会影响孔的形状和尺寸精度。然而，这种影响还没有完全被理解。为了实现这一目标，本文提出了一个尺寸分析的孔与硬质合金钻头在AISI P20钢的乳化液，最小量的润滑剂和干加工的流体应用。分析的尺寸参数是孔的直径和圆度。可以特别强调形状结果，其在不同深度（孔的开始、中间和结束）以及沿着孔的数量的演变进行评估。与文献相比，调查结果的一些差异是由于在孔壁上形成了粘附，这是由于在这种特殊的严重性条件下通过边缘造成的。
Drilling is one of the machining processes most used by manufacturing companies and is very complex from the perspective of scientific study. The geometry and the surface are generated in a single operation with many influential parameters. Geometric and dimensional control are more critical when the use of cutting fluids is reduced or eliminated because the temperatures in the process can influence the shape and the dimensional accuracy of the holes. However, this influence is not completely understood. With this goal, this article presents a dimensional analysis of holes made with carbide drills in AISI P20 steel under the fluid application of emulsion, minimal quantities of lubricant and dry machining. The dimensional parameters analyzed were the diameter and the circularity of the holes. Special highlight can be given to shape results, which were evaluated at different depths (beginning, middle and end of the hole), and along the evolution of the number of holes. Some differences of the investigated results compared to the literature are due to the formation of adhesion on the wall of the hole, resulting from passage of the edge on this particular severity condition.
