概要: In the honing operation, the influence of the honing head design on the out of roundness of a workpiece is investigated theoretically. Harmonic analysis is applied to fit the curve to the shape of the cross section of the workpiece. Using the three-stick honing head, the amplitude of waves of degree 3, 6, 9, ··· is attenuated more rapidly than that of waves of degree 2, 4, 5, 7, ··· as the honing proceeds. The four-stick honing head can not attenuate the amplitude of waves of degree 3, 5, 7, 9, ··· but attenuates that of waves of degree 2, 4, 6, ···. In the case of the honing head with greater sticking, the amplitude of some waves is amplified. The influence of the space of stick and shoes around the periphery of single-stick honing head on the out of roundness is investigated. 続きを見る

概要: The honing temperature of a cylindrical workpiece of steel is investigated both experimentally and theoretically. The experiment is carried out by using a vertical honing machine consisting of a constant pressure stone system. The temperature distribution in the workpiece is measured by means of a thermocouple formed by spot welding at the bottom of a small hole. The influence of its temperature on the finishing accuracy is also studied. The results obtained are as follows. The change of the cutting condition of sticks can be found from the variation of temperature in the surface layer of a workpiece. On the distribution of temperature in the workpiece, its gradient in the radial direction is small, but that in the axial direction is not so small. Using the suitable model of honing operation, the theoretical equations representing the influence of honing conditions on the temperature of workpiece were obtained. These equations explain the experimental result well. For example, the temperature becomes larger in proportion to the honing speed and the stone pressure, and the heat flux into the workpiece decreases as operation proceeds. 続きを見る

概要: The fundamental characteristics of a new type of infrared radiation pyrometer using an optical fiber are investigated theoretically and experimentally. The structure of this pyrometer is that the optical fiber accepts the infrared flux radiated from the object and transmits it to an infrared detector InSb cell. This I. R. P. is suitable for measuring the temperature of a very small object whose temperature changes rapidly. The flexibility of the optical fiber also makes it possible to measure the inner temperature of the object by drilling a microscopically fine hole in it and inserting the fiber. Three types of optical fiber were employed : quartz fiber, fluoride fiber and chalcogenide fiber. The main results obtained are as follows. The setting location of the fiber is independent of the total energy Accepted by the fiber, even if the object of a flat surface is not placed vertically to the axis of the fiber. This result is also applied to the object of a curved surface. The target area of the graded-index fiber is smaller than that of the step-index fiber when they are placed at a same distance from the object. The I.R.P. with the chalcogenide fiber can be useful for temperatures above 50°C. 続きを見る

概要: Both an evaluating function d to present the overall severity of superfinishing conditions and an equation ks to calculate the specific finishing energy are derived theoretically, assuming that one stick corresponds to a single point tool with a long cutting edge. Some experiments are carried out to confirm the propriety of these results. The ks-d relation calculated from the experimental results is useful in the evaluation of the machinability of work materials and the cutting ability of the stick. Moreover, this relation makes it possible to compare the superfinishing in the production rate and the surface refinement with the honing. 続きを見る

概要: Using the honing machine, the influence of the honing head design on the out of roundness of workpiece is investigated experimentally. Experimental results for three and four-stick honing heads agree well with the theoretical results obtained in the 1st peport. In the case of the honing head with greater sticking, the simulation of honing operation is carried out using the micro computer and the results obtained are compared with the theoretical results. 続きを見る

概要: Temperature of interface between a cutting tool and a workpiece is measured using two-color pyrometer with a fused fiber coupler. A conical tool is used as the cutting tool which is made of translucent alumina sintered under HIP, and 0.55% carbon steel is used as a workpiece. The infrared rays radiated from the interface and transmitted through the conical tool are accepted by a fused fiber coupler and led to two infrared detectors of different spectral sensitivity. Temperature is obtained by calculating the ratio of the output voltage from these two detectors. The results obtained are as follows. The temperature increases very rapidly and reaches 1000°C at about 40 μs after the beginning of cutting. The rate of increase of temperature is very great : about 108 °C/s at the cutting speed of 1 500 m/min. The temperature increases with the increase of cutting speed, but at a speed faster than 1000 m/min its influence is small. The temperature shows a tendency to saturate about 1300-1400°C as the cutting speed increases. 続きを見る
