小孔钻在工程塑料片材方面及其精度估算(中文3400字,英文2600字)
摘要
在最近的制造流程中，小直径钻孔由于其良好的特性经常被使用。钻孔工艺能够轻易的适用于大部分尺寸，加工精度，加工点孔，等等。许多有小直径孔的机械零件，是使用优质金属材料和机器特性制造出来的。然而，在最近的加工技术中，钻一个直径小于1 毫米的孔也是不容易的。在这份报告中，直径为1毫米的孔在两个工程塑料板材的钻孔和钻孔的精度进行了讨论。

Small-hole drilling in engineering plastics sheet and its accuracy estimation

Abstract
In recent manufacturing processes, the small diameter hole drilling process is frequently used owing to its good characteristics. The drilling process can easily be adapted to wide variations in lot size, processing accuracy, processing spot patterns where holes are made, and so on. Many machine elements, which have small diameter holes, are manufactured using engineering plastics of superior material and machining properties. However, it is not easy to drill holes with a diameter smaller than 1 mm, in recent machining technology as well. In this report, 1-mm diameter holes are drilled on two engineering plastics sheets and their  drilling  accuracy is discussed.
