ジャーナル フリーFew research works have been reported so far on the tightening of bolted joints by means of successive impacts, whereas the impact-wrenching is one of the most practical methods for the tightening of bolted joints. The process of the tightening of bolted joints by means of the swinging hammer is analysed and the theoretical results are compared with the experimental data. The substantial agreements between the theory and the experiment are confirmed. The results are summarized as follows. (1) The clamping force by an impact of the swinging hammer is concerned in the square root of the available energy of the hammer. (2) The increase of clamping force by an impact depends not only on the available energy of the hammer but also the existing clamping force just before the impact and the stiffnesses of the bolt and the clamped parts. (3) The clamping force by successive n impacts is proportional to √n·F1, where F1 is the initial clamping force.抄録全体を表示PDF形式でダウンロード (869K) -

ジャーナル フリーIn this paper it is reported that the behavior under tensile load and the influences of lubricants on fastening of polycarbonate (PC) screw are investigated experimentally as the first step to establish the strength design system of plastic screw. Firstly the tensile strength of PC screw is examined varying the strain rate. As a result, it is clarified that the tensile strength of PC screw using its stress area agrees well with that of cylindrical testpiece similarly to the case of steel screw. Secondly, a new concept of the equivalent residual strain is proposed to define the proof stress as it is difficult to decide the permanent strain after unloading in such viscoelastic materials as plastics and the stress corresponding to 0.2% equivalent residual strain is defined as the proof stress of PC screw. Finally, as a result of tightening test using some lubricants, it is proved that tightening can be achieved relatively smoothly by using silicon grease as lubricant.抄録全体を表示PDF形式でダウンロード (1058K) -

ジャーナル フリーOn the constant infeed honing, its cutting mechanism and influence of operating conditions on finishing performance are investigated. Moreover, applicability of the evaluating value di, presented in the previous paper to express the severity of operating conditions, is examined. The results are as follows. In this honing operation, three typical cutting characteristics are observed as the operating condition becomes severe : that is, glazing type, transition type and breaking type of cutting edges. In the transition type, cutting characteristic changes from glazing to breaking at a stage in process of operation. As compared with the constant pressure honing, the workpiece is hardly machined like a barrel in shape, even in the case of a large over-run. di is found to be much ful for the effects of infeed rate and cutting speed, but a little for crosshatch angle. The surface roughness of finished workpiece can be improved by applying spark-out, but there is naturally a limit of improvement. As the peaks of roughness are cut by spark-out, the surface profile is similar to that of the plateau honing. And, spectrum analysis of the roughness makes it clear that the roughness is composed of many waves of which wave length is various but amplitude is approximately equal.抄録全体を表示PDF形式でダウンロード (1032K) -

ジャーナル フリーMeasurements of transient cutting force are very often required for analyzing of the transient phenomenon in cutting or detecting tool chipping. However, with most existing tool dynamometers which detect cutting force through the strain, accurate measurements of transient cutting force cannot be expected becauce of insufficient frequency characteristics or time lag. This paper treats with the proposal of a new method to measure the transient cutting force. In this method, cutting force is calculated by means of a digital Fourier analyzer from the output of a tool daynamometer and the transfer funcution, which has been identified in advance under the same setup as that of the foregoing cutting test. The assessment tests have revealed that thus calculated cutting force is extremely close to the real value regardless of the dynamic rigidity of the tool dynamometer. This method is also applicable for accurate detection of acceleration of a simple system.抄録全体を表示PDF形式でダウンロード (990K) -

ジャーナル フリーIn the research, wheel wear rate B and actual metal removal rate Ztp were measured over a wide range of theoretical metal removal rate Zth. By using the results, the grinding ratio GB and the Ztp in high-depth of cut grinding have been investigated mainly. The conclusions obtained are as follows : (1) At the Zth within a critical theoretical metal removal rate (Zth) cr, the grain fracture is related to the B. At the Zth the Band the GB do not show large variation for varying Zth. And, the Ztp is regarded as being approximately equal to the Zth. (2) At the Zth over the (Zth) cr, the bond fracture is related to the B. From the (Zth) cr, the B and the GB begins to increase and decrease steeply with the increase of Zth. And, the Ztp begins to become outstandingly smaller than the Zth (3) The (Zth) cr, becomes larger for wheels of coarser grain and harder grade. Grain type in wheel influences the value of the (Zth) cr. (4) The Zth, from which Ztp does not increase with the increase of Zth, exists. (5) The sum of machining cost and wheel cost shows the minimum at a Zth near the (Zth)cr.抄録全体を表示PDF形式でダウンロード (1204K) -

ジャーナル フリーIn order to effectively control chip disposal in finish turning, a specially designed tool, Helicoidal Faced Cutting Tool (H. F. T.) of which side rake angle is continuously varied from positive to negative towards the tool point, has been developed. The twisted face makes tightly curled chips in a definite direction which are easily broken in adesirable length. Firstly, the mechanism of chip formation with the twisted face has been studied in two-dimensional cutting of copper alloy tube. In finish turning of low carbon steel with H. F. T., it has been clarified that the effect of twisted face is highly emphasized at a larger rake angle gradient than 20 deg/mm, and the tool effectively works even in the combination of feed rate lower than 0.05 mm/rev and depth of cut smaller than 0.5 mm.抄録全体を表示PDF形式でダウンロード (1214K) -

ジャーナル フリーThe purpose of this paper is to clarify the characteristics of cutting noise and noise sources in metal cutting with a single point cutting tool. When a cylindrical workpiece is machined with a lathe, the sound pressure level and frequency analyses were measured. Effects of overhang length of the cutting tool, cutting condition, tool wear, work material and shape of the workpiece on thecutting noise analyses were experimentally made clear. Two prominent peaks of the sound pressure level were observed from the frequency analyses of cutting noise at the frequencies of around 4 000 Hz and 10 000 Hz. The former peak is caused by the vibration of the cutting tool system and the sound pressure level at the frequency increased with the increase of tool wear. The latter peak is affected by the workpiece system and the frequency of the peak varied with the decrease of wall thickness in pipe cutting with a lathe.抄録全体を表示PDF形式でダウンロード (1227K) -
