摘要： PROBLEM TO BE SOLVED: To drastically shorten the manufacturing time by shaping one face or both faces of a plate member so as to obtain a prescribed vane shape after molding and then molding. SOLUTION: A plate member composed of a prescribed material is blanked into a vane shape to form the plate member 1, which is shaped into a preset prescribed material shape so as to be into a prescribed vane shape after the molding and a shaped material 2 is formed. The shaped material 2 is molded into a prescribed vane shape to form a vane 3. A method for deciding a prescribed material shape of the shaped material 2 is that a difference in the shape before and after the molding is given to a contact face between a cope and a drag of the shaped material 2 to be molded as a forced displacement in the direction (vertical direction) for moving the die so as to find a prescribed material shape based on an elastic analysis or an elasto-plastic analysis taking account of the characteristics of a prescribed material using a boundary condition found by approximatively simulating the inverse process of the molding.

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a hydraulic-turbine runner, achieving reduction of manufacturing time and manufacturing cost.
SOLUTION: With a cutter 12 of an NC machine tool 10, a partitioned blockish material 2 of a model of a Francis hydraulic turbine runner 1 is vertically halved; a halved lower blockish material 2a and an upper blockish material 2b cut by the NC machine tool 10; the surfaces of the blockish materials are polished by a grinder. Next, a base 5 for working and a lower vane 6a are welded so that the shapes of each lower vane 6a and each upper vane 6b on the base 5 for working on a crown 3 are formed in a continuous shape. Then, along the shapes of the lower vanes 6a and the upper vanes 6b, unnecessary base 5 for working is shaved off. Polishing by a grinder is effected for the surface from which the base 5 for working has been shaved off. On the crown 3, a vane 6 made up of the upper vane 6b, part of the base 5 for working, and the lower vane 6a is manufactured.

摘要： PURPOSE:To improve the efficiency of workpiece by providing a non-contact type distance measuring unit on a spindle head as well as an arithmetic unit on an NC control unit, and controlling the inclination angle of the spindle head. CONSTITUTION:The operation target amount stored in a memoy part 3 is taken out by one step and operation is made to the cutting position of a workpiece through a control part 4. next, the distance to the surface of ther workpiece is measured by non-contact type distance measuring units 10a, 10b, and the distance value is transferred to the aruthmetic part 5 of the NC control unit 1. With the comparison between the distance values transferred from the computation part 5, the distance between the non-contact type distance measuring units 10a, 10b as well asd the difference therebetween the inclination angle of a spindle head 8 is computed. Based on the result, the spindle head 8 is inclined through the control part 4. Then the cutter vector to the workpiece, that is, the attitude of cutting tool attached to the spindle head 8 is controlled properly and the operation is carried out on the whole workpiece.

摘要： PURPOSE:To automatically avoid the interference of an object to be worked and a cutter by operating the interval quantity of the cutter and the object to be worked from data of a shape of the object to be worked, a shape of the cutter and a cutting position of the object to be worked. CONSTITUTION:A cutter offset point Pi being a center point of a cutter 11 for cutting a blade face 9 and a cutter vector are derived in advance from a host computer, and these point and vector and blade face design data are inputted to an NC device through a storage medium. In the NC device, a comparing operation with a mesh-like data group for expressing a blade face shape is executed at every one point of the inputted cutter offset point Pi and cutter vector Vi, and whether an interference exists or not is discriminated. In the case when the interference exists, the cutter vector Vi is rotated by a designated angle DELTAtheta in the direction separated from the interference face, and by repeating it until the interference comes not to exist, a new cutter vector Vi is derived.

摘要： PURPOSE:To grind a work uniformly as well as to aim at improvement in the extent of grinding accuracy, by installing a photosensor in a support plate supporting a grinding wheel in addition so as to detect a spark of the grinding wheel, while detecting a generated state of the grinding spark with the photosensor, and constituting it to control a posture of the grinding wheel on the basis of this detection. CONSTITUTION:If a work W is curved, a grinding wheel 13 comes into a state of being deflected to this work W, whereby an (a) part of the wheel 13 comes into one-sided contact with the work W, and a grinding spark generated state occurs in this (a) part alone. When this spark is received by a first photosensor 15a, it is operated at a comparator of a control circuit 16 and then an output signal of this control circuit 16 is transmitted to actuators 2 and 3, whereby the (a) part and a (b) part of the grinding wheel 13 comes into uniformly contact with the work W by both these actuators 2 and 3, thus the work is ground. In consequence, two photosensors 15a and 15b are made so as to receive almost the same spark.
