本文介绍了在柏林理工学院机床实验室进行的实验情况。在进行适当的切割试验之前，要对车床和所使用的仪器进行研究，以确定它们在各种条件下的性能。在主要试验中，旨在确定以下因素对切削力的影响：切割速度、切屑截面、刀具形状和被切割材料的特性。作为这些观察的结果，设计了一种新形式的刀具，作者声称，这种刀具允许比目前使用的标准刀具具有更高的切割速度和更大的切屑截面。给出了在德国各铁路车间进行的部分试验结果，其中比较了在完全相同的条件下新旧刀具刃口的相对寿命。据称，从外国各商店获得的结果来看，通过这种新工具，平均而言，产量可以提高约30%。
This paper gives an account of experiments conducted in the machine-tool laboratory of the Polytechnic Institute of Berlin. The cutting tests proper were preceded by a study of the lathe and the instruments used, to ascertain their behavior under various conditions. In the main tests it was aimed to determine the influence upon the cutting forces of the following factors: Cutting speed, chip section, shape of tool, and characteristics of the materials cut. As a result of these observations a new form of tool has been designed which, the author claims, permits a higher cutting speed and a larger chip section than is practicable with the standard tools now used. The results of some of the tests made in various German railway shops are given, in which the relative life of the cutting edges of the new and the old tools under exactly the same conditions was compared. It is claimed, from results obtained in various foreign shops, that on the average production can be increased about 30 per cent by means of the new tool.
