By analyzing the characteristic features of the variations of temperature in the workpiece surface layer during grinding and the thermal inertia of the thermocouple, this paper reviews the reliability of the method recommended by Koya Takazawa of the dynamic temperature measurement by means of the single-wire thermocouple, and presents a method by which the dynamic response ability the instrument for temperature measurement should possess may be approximately evaluated according to the grinding conditions. On the basis of these discussions are given the experimental results of the grinding forces and the temperature distributions in the ground surface layer during surface grinding of the titanium alloy (Ti-6AI-4V) and the carbon steel(45°).Aoeording to the experimental results quantitative comparison and analysis are made in several respects of the grindability of titanium alloys and carbon steels. This shows that the peak temperature on the workpiece surface of titanium alloys is not much higher than that of carbon steels under the grinding conditions of this experiment,while the grinding ratio of Ti-6Al-4V is only about 1/45 that of 45# steel. The grinding chips of titanium considerably adhere to the abrasive cutting edges. From the experimental results, we find that, the main reason titanium alloys are hard to grind is not the high temperatures existing in grinding area,but the drastic chemical affinity of titanium alloys for, abrasive materials. Therefore, an intensive research, which seems to be the key to the fundamental improvement of the grindability of titanium alloys, should be carried on for the mechanism of the chemical affinity and for the inhibition of as much affinity as possible by selecting the best type of abrasive materials, and the suitable grinding fluid, and the optimal grinding speed.Attached to the end of this paper is a general computing programe for regression analysis of the experimental data, applicable to metal cutting experiments.

本文通过分析磨削时工件表层温度的变化规律以及热电偶的动态响应能力,对高泽所推荐的单丝热电偶动态测温方案的可靠性进行了论证,并在此基础上提供了有关平磨钛合金与45~#钢时的磨削力与工件表层内部温度分布的实测数据。文章在根据实测结果对钛合金与45~#钢的磨削性的几个方面定量地进行了综合分析以后指出,在实验所采用的磨削条件下,钛合金试件表面峰值温度与45~#钢相比偏高并不明显。但是两者磨削比却相差近45倍。此情况说明通常推测的磨削区高温并非TC—4难磨的根源,钛合金难磨的本质原因是它与磨料之间的激烈的化学亲和作用。因此深入研究这种化学亲和的机理,通过优选新型磨料、磨削液以及最佳磨削速度尽可能地去抑制这种化学亲和作用,应该是从根本上改善钛合金磨削性的关键。

In this paper, formulas of bending moment, stress and deflection for a circular ring are derived. The characteristics of a circular ring used as the elastic element of a dynamometer are discussed, and it is show that a thick ring with a larger ratio of t/R shoud be adopted rather than a thin ring. Three dynamometers for surface grinding of the elongated octagonal-ring type of different sizes and different designs are developed. Calibrations and grinding tests show that the characteristics of an elongated octagonal...

In this paper, formulas of bending moment, stress and deflection for a circular ring are derived. The characteristics of a circular ring used as the elastic element of a dynamometer are discussed, and it is show that a thick ring with a larger ratio of t/R shoud be adopted rather than a thin ring. Three dynamometers for surface grinding of the elongated octagonal-ring type of different sizes and different designs are developed. Calibrations and grinding tests show that the characteristics of an elongated octagonal ring are similar to those of a circular ring and that the double elongated octagonal-ring type dynamometer with an integral thick wall is a satisfactory design.

本文对圆环的弯矩、应力及位移的计算公式进行了推导,并分析了圆环作为测力仪弹性元件的特性,从而证明以圆环作为测力仪弹性元件时,应采用t/R比值较大的厚环,而不宜采用薄环。研制了三种尺寸及不同结构的八角扁环式平面磨削测力仪,经标定及磨削试验证实,圆环的规律性也适用于八角扁环,并且整体厚壁双八角扁环式测力仪是一种性能较好的平面摩削测力仪。
