ジャーナル フリーAmong the important check items of the profiles of the male and female screw surfaces of a ball screw, the outside and core diameters of the screw spindle, the inside and core diameters of the nut, and the pitch can be measured by the same procedure as for the ordinary triangular thread. The theory and the practical method of the measurement of the ball center locus diameter were reported in last two parts of the report.
Here, the measurement of the contour of the screw surface by the optical procedure, the precise correction method and the approximate correction method of the observed value are discussed.抄録全体を表示PDF形式でダウンロード (1296K) -

ジャーナル フリーIt can be assumed that mechanism of conventional simple spinning consists of drawing process and ironing process from the previous experimental results. This report deals with an analysis of drawing process in detail. Drawing process is characterized by the fact that bending deformation may be caused at first along the part where the blank begins to conact with the roller, and drawing deformation may be followed on the radius of round-off of the roller. The analysis of these deformations are performed respectively. The calculated results are checked by the experimental results and the agreements are good. As the results, it is evident that bending deformation is important in spinning.抄録全体を表示PDF形式でダウンロード (1264K) -

ジャーナル フリーThe tools with artificially restricted tool-chip contact length have a strong tendency to produce a complicated plastic flow ahead of the rake face as far as the restricted length is shorter than the natural tool-chip contact length. The paper stresses the importance of the plastic field for better understanding of the machining characteristics with the reduced contact tools.
By applying the theory of plasticity, the plastic field is found to be composed of one centered fan and two straight slip line fields.
The associated fields of stress and velocity with the slip line construction are found to satisfy all boundary conditions. Thus the slip line field proposed in the paper is one of the Mises solution.
The plastic deformation during chip forming process is obtained analytically as a deformed pattern of originally square grids printed on the side of work piece. The analytical pattern is verified to be in good agreement with the pattern actually produced in experiments.抄録全体を表示PDF形式でダウンロード (4310K) -

ジャーナル フリーIn order to investigate the worked layers of polished semiconductor crystals, the ultra microscratching hardness tester has been made in trial, the load of which is given in the range from 10 to 5, 000 mg. By the use of a very sharp diamond triangular pyramid, plastic flow can easily be realized on crystal surfaces, and the widths of scratches are measured by an electron microscope. The relation between the scratching load and the deformation is clarified on optically polished germanium.抄録全体を表示PDF形式でダウンロード (13547K) -

ジャーナル フリーThe required conditions for face milling with sintered carbide blades are extremely critical, this being especially so with the case where a hardened alloy steel is machined. This is the reason why the machining standards for face milling is difficult to be estaslished. In order to overcome this, the methodological investigation for the test procedure is essential.
Important factors to govern the tool life such as carbide grade, tool shape, depth of cut, feed, speed, engage angle, shock number, path ratio, etc.have been investigated experimentally.抄録全体を表示PDF形式でダウンロード (5606K) -

ジャーナル フリーA SIP model 4 type screw cutting lathe which had been used in a machine shop for a long time, was repaired and altered to the screw thread lead tester with automatic recording equipment. By this investigation the following results were obtained.
(1) An electric micro-comparator with automatic recording equipment was made by utilizing wire strain gauges, and it was ascertained that it had the satisfactory accuracy and linearity for the lead tester.
(2) Periodic error of measurement which was caused by the eccentric rotation of the lead screw was fully eliminated by using a suspension type lead nut instead of the original one.
(3) The screw thread lead tester was enabled to measure with an accuracy of± 1 μ in the measuring range of 100 mm, by giving the correction curve to the plate cam and repairing several parts of the machine.
(4) Lead error of an internal thread could be measured without the influence of eccentric chucking.抄録全体を表示PDF形式でダウンロード (4713K) -

ジャーナル フリーRecently speed of industrial sewing machine has been required more and more, and furthermore, many kinds of new synthetic fibers have been used in every fields of dress makers. Owing to this fact, many problems caused by the overheat of sewing machine needle have come up.
In order to clear this problem, the authors measured the temperature of sewing needle in operation, in relation to the sewing materials, thickness of fabric, size of needle and operational speed of sewing machine.
There are many kinds of method to measure the temperature of the needle, and the authors picked up the "Potentiometer Method" as the most suitable one for this experiment.抄録全体を表示PDF形式でダウンロード (439K)
