ジャーナル フリーThe hydraulic control system to make the work speed reduced with the occurrence of chatter vibration is set up according to the principle of adaptive control for work regenerative chatter vibration, which was described in the previous paper, and the effects of adaptive control upon the suppression of the chatter vibration are experimentally examined by the grinding test.
It is made clear that the vibration can be surely controlled to occur if the responsibility of control system is chosen so sharp as to quickly respond to the amplitude modulated frequency of chatter vibration without any phase lag, or on the contrary, is chosen so dull as to slowly respond to the emvelope of modulated amplitude when the chatter grows up gradually.抄録全体を表示PDF形式でダウンロード (1114K) -

ジャーナル フリーThe purposes of this study are to analyze experiential way of determining polishing factors of conventional crank type lens polishing machine and to lay a base of controlling the wear of glass. The analysis has been made under the following four assumptions; (1) Wear is in proportion to polishing path length. (2) Wear is in proportion to pressure. (3) Polishing tool and workpiece contact uniformly over their whole surfaces. (4) Polishing tool rotates regularly, i. e. in each moment, rotational velocity of polishing tool is in proportion to square root of moment of force which acts on the tool. The analysis is made for both plane and spherical surfaces. The experimental results agree with the calculation.抄録全体を表示PDF形式でダウンロード (1342K) -

ジャーナル フリーIn both steady and operating states, the fundamental equations representing the correlation among the dimensions of elements and the working conditions of hydraulic copying control device are introduced when the various shapes of control ports are used in throttle valve. Based on these equations, the static and dynamic characteristics are examined theoretically and experimentally.
As a result, it is shown that the dimensions and working conditions of hydraulic copying control device have a great influence on the static and dynamic characteristics, and shown that the favourable characteristics can rarely be realized simultaneously both in steady and operating states. Hence, the optimum design of the control device must be determined with due regard to the operating conditions of the control device.抄録全体を表示PDF形式でダウンロード (1424K) -

ジャーナル フリーValues of specific grinding force obtained theoretically from grinding force were considerably larger than the values from experiments of single point cutting. One of reasons for this may be that most of the traditional papers are based on the two-dimensional distribution of cutting points in grinding wheel, that is, they neglect the existence of cutting points which do not cut the work directly, hiding themselves behind preceding cutting points.
In this paper, the specific grinding force in ploughing CP is introduced instead of the specific grinding force, and its values are obtained from values of the normal force measured in experiments, using the number of simultaneously cutting points and the grain cutting area which are analyzed theoretically on the three-dimensional distribution of cutting points.
In addition, CP values are given also from experiments of single point cutting. These values are slightly larger than values obtained from grinding forces. This appears to be caused by an essential difference of single cutting in which cutting is made intermittently and grinding in which successively.抄録全体を表示PDF形式でダウンロード (1454K) -

ジャーナル フリーThis paper describes that pitch signals used in the pitch measurement of machine elements, e. g., screw, rack and so on having periodic shapes can be detected by means of holographic interference. The conditions for applying the technique to the positioning of a flank of thread or a tooth surface of rack are to illuminate one measured surface with condenced beam of He-Ne laser at a high angle of incidence, and to utilize the regular reflected beam of its surface as the signal beam to make a hologram. The hologram, called 'frozen' hologram, is useful as a kind of matched filter relating to the displacement and shape informations. In the reconstruction process the screw or the rack is moved at constant speed along the axis in order to compare the hologram with 'live' holograms made in other measured surfaces. Then, the pitch signals can be detected regularly and continuously behind the hologram. The results obtained in the experiments are as follows. (1) The signal waveforms calculated theoretically are characteristic of the pitch signals detected. (2) The signals can be detected for long time with the repeatability of ±0.2μm per 40 times to the mean value.抄録全体を表示PDF形式でダウンロード (1231K)
